General Information
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

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.
