Compressor Modules

(SCM & MCM - 1U49 standard on all units)
The compressor modules, (Single Circuit & Multiple Circuit), upon receiving a request for
mechanical cooling, energizes the appropriate compressors and condenser fans. It monitors the
compressor operation through feedback information it receives from various protection devices.

Human Interface Module

(HI - 1U65 standard on all units)
The Human Interface module enables the operator to adjust the operating parameters for the unit
using it's 16 key keypad. The 2 line, 40 character LCD screen provides status information for the
various unit functions as well as menus for the operator to set or modify the operating parameters.

Heat Module

(1U50 used on heating units)
The Heat module, upon receiving a request for Heating, energizes the appropriate heating stages
or strokes the Modulating Heating valve as required.
