Unit Protection Module
(UPM)

Heat Pump Module

Every unit has an integral heat pump module that contains hermetic scroll-type compressor(s), a coaxial refrigerant-to-water heat exchanger(s), refrigerant flow reversing valve(s), expansion valve(s), liquid line filter drier, high pressure manual reset cutout, crankcase heater(s) and various sensors, service ports and safety devices which allows the unit to run at less than full capacity and results in fewer compressor cycles. The heat pump is intended to be connected to an external water source such as a water cooling tower or boiler, a geothermal source or even a ground loop. The module is piped to the airside coil located in the intake airstream and optionally to a reheat coil that will control humidity.

The location of components in the module will vary.

Control circuitry and the Unit Protection Module (UPM) for the heat pump module are located in the heat pump module. The UPM is a

printed circuit board and has LED fault indicator lights to indicate various alarm conditions and also power status. A unit- specific schematic for electrical circuits is located in the control center and another unit-specific schematic for heat pump

circuitry is located in the heat pump module.

Optional Electric Heaters

There are two optional electric heaters available. One is a preheater and is used to prevent frost buildup on the energy wheel. It is located directly in front of the intake air filter assembly. The second optional heater is used as a supplementary emergency heat source for the building and is integrated into the supply airstream.
