Heat Pump Module
Every unit has an integral heat pump module that contains hermetic
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
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.
