RT -PRC031 -EN 11 V A V Units Only Note: When noted in th is sequence “Human Interface P anel, ” the reference is to both the unit mounted and remo te mounted Human Interface P anel. All setpoint adjustments can be accomplished at the unit or Remote Human Interface Pa ne l.
12 RT -PRC031-EN Controls Variable Ai r Volume (VAV) Only temperature from se tpoint, i.e., the fur ther away from se tpoint, the faster the fresh air damper will open. Note : The economiz er is only allowed to functio n freely if one of the following conditions is met.
RT -PRC031 -EN 13 Controls Variable Ai r Volume (VAV) Only overheat. The supply air temperature setpoint is adjust ed based on the temperature of the critical zone(s). This can ha ve the effect of improving comfor t and/or lowering energ y usage. The user -defined parameters are the same as for outdoor air rese t.

The zone temperature cooling setpoint is user - defined at the Human Interface Panel or from the BAS/Network.
RT -PRC031 -EN 15 Controls Constant Volume (CV) Only Electr ic Heating The individual stages of electric heat will be sequenced on the z one demand. The number of available stages will depend on the unit s ize and heat capacity selected.
16 RT -PRC031-EN Common to V A V and CV Units S p a ce P re s s ure C o n t ro l - Statitr ac™ A pressure transdu cer is used to measure an d repor t direct space (building) static pressure.

When the tim e cloc k switc hes from night setbac k to o ccupied mode, all heating/cooling fun ctions begin normal operation.
RT -PRC031 -EN 21 Controls VAV and CV If there is a call for economiz er cooling, the outdoo r air damper may be opened furthe r to satisfy the cooling request.
22 RT -PRC031-EN Exhaust/Retur n F an Options When is it necessary to provide building exhaust? Whenever an outdoor air econ omizer i s used, a building generall y requires an exhaust system. The purpose of the exhaust system is to exhaust the proper amount of air to prevent over or under -pressurization of the building .
RT -PRC031 -EN 23 Applications Considerations The T rane 1 0 0 percent modulating exhaust system with Statitrac provides ef ficient control of buildin g pressure in most applications simply because 1 .

RT -PRC031 -EN 25 Applications Considerations When using an IntelliP ak II Air Handler for horizontal supply an d/or return, an additional pressure drop must be added to the supply external static to account for the 90 degree turn the air is makin g. This additiona l pressure drop depends on airflow and air handler siz e, but a range of 0.
26 RT -PRC031-EN Applications Considerations will help reduce soun d transmission. The ASHRAE publication "A Practical Guide to Noise and V ibration Control for HV AC Systems" also pro v ides valuable i nformation. There are several other sources of unit sound, i.
RT -PRC031 -EN 27 Applications Considerations Duct Design It is impor tant to note that the rated capacities of the ai r handler can be met only if the air handler is properly installed in the field. A well-designed duct system is essential in m eeting these capacities.
28 RT -PRC031-EN This section outlines a step-by -step procedure that may be used to select a T rane air handler . The sample selection is based on the following conditions: Summer Design: • Summer outdoo r design conditions - 95 DB/7 6 WB ambient temperature • Summer ro om design conditions -78 DB/65 WB • T otal cooling load - 980 MBH (81 .
RT -PRC031 -EN 29 Selection Procedure at 95°F is approximatly 1336 MBH total coolin g and 969 MBH sensible cooling capacity . Step 6 - Det er mine Leaving Air T emper atur e Unit sensible heat capacity cor rected for supply air fan motor heat = 969 MBH S ensible - 1 09.
30 RT -PRC031-EN Selection Procedure Exhaust F an Motor Sizing The exhaust/r eturn fan is selected based on total return system nega tive static pressur e and exhau st fan CFM. Return system neg ative static includes return duct static, and any other job site applicable static pressure drop.
