Reducing deflection discourages sound transmission. 2 Duct Design It is important to note that the rated capacities of the rooftop can be met only if the rooftop is properly installed in the field. Instead. Several basic guidelines for unit placement should be followed to minimize sound transmission through the building structure: 1 Never cantilever the compressor end of the unit. they should be staggered to reduce deflection over that span. The satisfactory distribution of air throughout the system requires that there be an unrestricted and uniform airflow from the rooftop discharge duct. 1 Clearance Requirements To assure proper diffusion of exhaust air before contact with the outside air intake of adjacent unit. To reduce span deflection if more than one unit is placed on a single span. conference rooms. exhaust air removal and condenser airflow? If screening around the unit is being used. A well designed duct system is essential in meeting these capacities. A structural cross member must support this end of the unit. ideal locations might be over corridors. If possible. the loss of capacity and static pressure may be reduced through the use of guide vanes and proper direction of the bend in the elbow. The high velocity side of the rooftop outlet should be directed at the outside radius of the elbow rather than the inside. consider the following: Do the clearances available allow for major service work such as changing compressors or coils? Do the clearances available allow for proper outside air intake. is there a possibility of air recirculation from the exhaust to the outside air intake or from condenser exhaust to condenser intake? Actual clearances which appear inadequate should be reviewed with a local Trane sales engineer. roof joists must be replaced by a structural shape in the critical areas described above. If the clearances shown are not possible on a particular job. or over. 4 If several units are to be placed on one span. executive office areas and classrooms. When two or more units are to be placed side by side. a column or main support beam. The recommended clearances identified with unit dimensions should be maintained to assure adequate serviceability. toilets or other areas where higher sound levels directly below the unit(s) are acceptable.Application Considerations Acoustical Considerations Proper placement of rooftops is critical to reducing transmitted sound levels to the building. rooftops should not be located directly above areas such as: offices. However. since this depends on the response of the roof and building members to the sound and vibration of the unit components. This discharge section should be straight for at least several duct diameters to allow the conversion of fan energy from velocity pressure to static pressure. The units should also be staggered for two reasons: It is impossible to totally quantify the effect of building structure on sound 12 RT-PRC007-EN . utility rooms. the guidelines listed above are experienceproven guidelines which will help reduce sound transmissions. And the most economical means of avoiding an acoustical problem is to place the rooftop(s) away from acoustically critical areas. when job conditions dictate elbows be installed near the rooftop outlet. The ideal time to make provisions to reduce sound transmissions is during the design phase. 2 Locate the unit center of gravity which is close to. maximum capacity and peak operating efficiency. However. the distance between the units should be increased to 150 percent of the recommended single unit clearance. 50/60 Hz transmission. 3 If the roof structure is very light.

Inlet guide vane assemblies installed on the supply fan inlets regulate fan capacity and limit horsepower at lower system air requirements. If the enthalpy of the outside air is appropriate to use “free cooling. during unit start up and transition to/from Occupied/Unoccupied modes to prevent overpressurization of the supply air ductwork. Note that the economizer is only allowed to function freely if ambient conditions are below the enthalpy control setting or below the return air enthalpy if unit has comparative enthalpy installed. When the outside air temperature is low and the building cooling load is low. the amount of “spin” induced by the vanes increases at the same time that intake airflow and fan horsepower diminish.” the economizer will be used first to attempt to satisfy the supply setpoint. However.The amount is zero where they are equal and increases linearly toward the value set at the reset amount input. the further away from setpoint. The inlet guide vanes will close when the supply fan is shut down. There are two user-defined parameters that are adjustable through the VAV Setpoint Potentiometer: reset temperature setpoint and reset amount. The supply air temperature setpoint is user-defined at the unit mounted VAV Setpoint Potentiometer or at the remote panel. The drive will accelerate or decelerate as required to maintain the supply static pressure setpoint. the supply air setpoint can be raised.. On units with economizer. primary cooling only is used to satisfy cooling requirements. the supply fan is shut down and the inlet guide vanes are closed. and the inlet guide vanes are modulated to maintain the supply air static pressure within an adjustable user-defined range. or on outdoor air temperature. return air temperature. At outdoor air conditions above the enthalpy control setting. If the overpressurization condition occurs on the fourth time. This reset can lower usage of primary cooling and result in a reduction in primary cooling energy usage. A pressure transducer measures duct static pressure.. As the vanes approach the full-closed position. The maximum value is 20 F. The range is determined by the supply air pressure setpoint and supply air pressure deadband. thereby preventing subcooling of critical zones. if for any reason the supply air pressure exceeds the fixed supply air static pressure limit of 3. The amount of reset applied is dependent upon how far the outdoor air temperature is below the supply air reset setpoint. Bypass control is offered to provide full nominal airflow in the event of drive failure.5” W. i. the faster the fresh air damper will open. Variable frequency drives provide supply fan motor speed modulation. If the unit does not include an economizer. A pressure transducer measures duct static pressure. which are set through a unit mounted potentiometer. A field adjustable potentiometer on the Economizer Actuator. and the VFD is modulated to maintain the supply air static pressure within an adjustable user-defined range. Supply Air Setpoint Reset Supply air reset can be used to adjust the supply air temperature setpoint on the basis of a zone temperature.Controls VAV Units Only Variable Frequency Drives (VFD) Control Sequence of Operation Variable frequency drives are driven by a modulating 2-10 vdc signal from the VAV module. The rate of economizer modulation is based on deviation of the discharge temperature from setpoint. the vanes pre-spin intake air in the same direction as supply fan rotation. When subjected to high ambient return conditions the VFD shall reduce its output frequency to maintain operation. a Reset Based on Outdoor Air Temperature Outdoor air cooling reset is sometimes used in applications where the outdoor temperature has a large effect on building load. If the outdoor 49 . a call for cooling will modulate the fresh air dampers open. The unit is then allowed to restart three times. 1 Supply Air Pressure Control Inlet Guide Vane Control Inlet guide vanes are driven by a modulating 2-10 vdc signal from the VAV Module. primary cooling only is used and the fresh air dampers remain at minimum position. or a remote potentiometer can provide the input to establish the minimum damper position.C. which are set through a unit mounted potentiometer. Supply Air Static Pressure Limit The opening of the inlet guide vanes and VAV boxes are coordinated. The range is determined by the supply air pressure setpoint and supply air pressure deadband. Supply air reset adjustment is available on the unit mounted VAV Setpoint Potentiometer for supply air cooling control. RT-PRC007-EN 2 Supply Air Temperature Controls Cooling/Economizer During occupied cooling mode of operation.e.Tracer™. the unit is shut down and a manual reset diagnostic is set and displayed at any of the remote panels with LED status lights or communicated to the Integrated Comfort system.” the fresh air dampers drive to the minimum open position. If outside air is not suitable for “economizing. the economizer (if available) and primary cooling are used to control the supply air temperature. with respect to time. When in any position other than full open. On units with economizer.5 F. the heat will be staged down. primary cooling only is used to satisfy cooling requirements. When MWU is activated the economizer damper is driven fully closed.The RTRM will energize the supply fan contactor 45 seconds after the initiation of the heat cycle. The rate of economizer modulation is based on deviation of the zone temperature from setpoint. A field adjustable potentiometer on the Economizer Actuator. When the zone temperature meets or exceeds the MWU setpoint then MWU will be terminated and the unit will switch over to VAV cooling. the economizer (if provided) and primary cooling are used to control zone temperature. primary cooling only is used and the outdoor air dampers remain at minimum position. At outdoor air temperatures above the enthalpy control setting.The IGN relay brings on the combustion fan motor. Tracer or a remote potentiometer can provide the input to establish the minimum damper position. Electric Heating When heat is required. then primary cooling will be staged up as necessary. the further away from setpoint.5 F below the MWU setpoint. The userdefined parameters are the same as for outdoor air reset.The RTRM will cycle first stage heat on and off as required to maintain zone temperature.. Heating Gas Heating When heating is required the RTRM initiates the heating cycle through the ignition control module(s) (IGN). Daytime Warm-up During occupied mode. the RTRM terminates the heat cycle. If outside air is not suitable for “economizing.The unit is then 50 CV Units Only Sequence of Operation 1 Occupied Zone Temperature Control Cooling/Economizer During occupied cooling mode. Note that the economizer is allowed to function freely only if ambient conditions are below the enthalpy control setting or below the return air enthalpy if unit has comparative enthalpy. When the zone temperature meets or exceeds the MWU setpoint minus 1.” the fresh air dampers drive to the minimum open position. The ignition control module(s) begin the ignition process by preheating the hot surface ignitor(s). If the unit does not include an economizer. If the enthalpy of outside air is appropriate to use “free cooling”. 3 Zone Temperature Control Unoccupied Zone Heating and Cooling During Unoccupied mode. the economizer will be used first to attempt to satisfy the cooling zone temperature setpoint. Inlet guide vanes and VAV boxes are driven full open. the VAV boxes are fully opened and the CV heating algorithm is in control until the Morning Warm-up setpoint is reached. b Morning Warm-up (MWU) Reset Based On Zone Or Return Temperature Morning warm-up control (MWU) is activated whenever the unit switches from unoccupied to occupied and the zone temperature is at least 1. returned to VAV cooling mode.The first stage electric heater bank(s) will be energized if the appropriate limits are closed. The amount of reset applied is dependent upon how far the zone or return air temperature is below the supply air reset setpoint. the RTRM initiates first stage heating by energizing the first stage electric heat contactor. the unit is operated as a CV unit.e. Zone or return reset is applied to the zone(s) in a building that tend to overcool or overheat. First stage of cooling will be allowed to start after the economizer reaches full open. the RTRM will call for the second stage of heat by driving the combustion blower motor to high speed. When the space temperature rises above the heating setpoint. a call for cooling will modulate the fresh air dampers open. Logic for zone or return reset control is the same except that the origins of the temperature inputs are the zone sensor or return sensor respectively. If first stage cannot satisfy the requirement.The maximum value is 3 F. The system changes to CV heating (full unit airflow). the RTRM will energize the second stage electric heat contactor(s) if the appropriate limits are RT-PRC007-EN . The supply air temperature setpoint is adjusted based on the temperature of the critical zone(s) or the return air temperature. The amount is zero where they are equal and increases linearly toward the value set at the reset amount potentiometer on the VAV Setpoint potentiometer. and all stages of heat (gas or electric) are energized. if the zone temperature falls to a temperature three degrees below the Morning Warm-up setpoint. the inlet guide vanes are driven full open. If more capacity is needed to satisfy the heating setpoint. When ignition does occur the hot surface ignitor is deenergized and then functions as a flame sensor.Controls air temperature is more than 20 F below the reset temperature setpoint the amount of reset is equal to the reset amount setpoint. This can have the effect of improving comfort and/or lowering energy usage. The unit controls zone temperature to the Unoccupied zone cooling and heating (heating units only) setpoints. the faster the fresh air damper will open. If the return or zone temperature is more than 3 F below the reset temperature setpoint the amount of reset is equal to the reset amount setpoint. i.The Morning Warm-up setpoint is set at the unit mounted VAV Setpoint potentiometer or at a remote panel. If ignition does not take place the IGN(s) will attempt to ignite 2 more times before locking out. After the hot surface ignitor is preheated the gas valve is opened to ignite first stage. Daytime Warm-up is initiated. When MWU is activated the VAV box output will be energized for at least 6 minutes to drive all boxes open. The zone cooling and heating setpoints can be as close as 2 F apart. When the space temperature rises above the heating setpoint. One input is provided to request the pressurize mode. Control Sequences of Operation Common to Both VAV and CV Units Ventilation override (VOM) Applying 24 volts to one of the three Ventilation Override inputs manually activates ventilation override.

When any ventilation override mode is active. if the supply air temperature drops to 10 F below the occupied zone heating temperature setpoint.The RTRM will cycle second stage on and off as required while keeping stage one energized.The ICS can also initiate any ventilation override mode.” the mode will change to cooling or heating as necessary to satisfy the zone cooling and heating setpoints. the pressurize request will have priority followed by purge. If more than one mode is requested at the same time.The heat stage is dropped if the supply air temperature rises to 10 F above the occupied zone heating temperature setpoint. all heating and cooling is turned off.The CTI provides zone temperature control only and is mutually exclusive of theTrane Communications Interface (TCI).

Supply AirTempering This feature is available only with Tracer™ or with systems using programmable zone sensors (CV only with economizer). For gas and electric heat units in the Heat mode but not actively heating. For the case where the unit is required to turn off. The supply fan is energized approximately 1 second before the electric heat contactors. one stage of heat will be brought on to maintain a minimum supply air temperature. Unoccupied Zone Temperature Control Cooling and Heating Both cooling or heating modes can be selected to maintain Unoccupied zone temperature setpoints. heating or primary cooling operation can be selectively locked out at the remote panels or TRACER. the second input to request the purge mode.The CTI will allow only two steps of heating or cooling. the emergency stop input is used. the outdoor air dampers close and heating/cooling can be enabled or disabled. There are 3 ways to switch Occupied/ Unoccupied: 1 NSB Panel 2 Electronic time clock or field-supplied contact closure Trane’s night setback sensors are programmable with a time clock function that provides communication to the rooftop unit through a 2-wire communications link. the night setback sensor communicates the need for the rooftop heating/cooling (if enabled) function and the evaporator fan. Comparative Enthalpy Control of Economizer The Economizer Actuator receives inputs from optional return air humidity and temperature sensors and determines whether or not it is feasible to economize. airflow must be maintained through the rooftop unit. The rooftop unit will cycle through the evening as heating/cooling (if enabled) is required in the space. TRACER will switch the unit to the occupied mode.The supply fan is forced on until the FROSTAT device no longer senses a frosting condition or for 60 seconds after the last compressor is shut off. 52 Timed override Activation—Non-lCS When this function is initiated by the push of an override button on the programmable zone sensor. 3 When using the night setback options with a VAV heating/cooling rooftop. Unit operation (occupied mode) during timed override is terminated by a signal fromTRACER. RT-PRC007-EN . Automatic Cancellation of the Timed override Mode occurs after three hours of operation. the unit will switch to the occupied mode. The desired transition times are programmed at the night setback sensor and communicated to the unit. If the outdoor air enthalpy is greater than the return air enthalpy then it is not feasible to economize and the economizer damper will not open past its minimum position.The binary input is brought out to Low VoltageTerminal Board One (LTB1). When the time clock switches from night setback to occupied mode. Occupied/Unoccupied Switching Night setback (unoccupied mode) is operated through the time clock provided in the sensors with night setback. All compressors are turned off after they have met their minimum 3 minute on times. whichever is longer. Emergency Stop Input A binary input is provided on the RTRM for installation of field provided switch or contacts for immediate shutdown of all unit functions. Either of these methods will assure adequate airflow through the unit and satisfactory temperature control of the building. When the time clock switches to night setback operation. Fan Failure Switch The fan failure switch will disable all unit functions and “flash” the Service LED on the zone sensor. As the building load changes.Controls Coil Freeze Protection FROSTAT™ The FROSTAT system eliminates the need for hot gas bypass and adds a suction line surface temperature sensor to determine if the coil is in a condition of impending frost. If impending frost is detected primary cooling capacity is shed as necessary to prevent icing. all heating/cooling functions begin normal operation. TRACER Timed override Activation—ICS Night Setback Sensors When this function is initiated by pushing the override button on the ICS sensor. This can be accomplished by electrically tying the VAV boxes to the VAV heat relay contacts on the Low voltage terminal board or by using changeover thermostats. MOP.
