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.
Modulating Dehumidification Module
MDM
(Optional 1U107 - used with Dehumidification
Control)
The MDM supports specific control inputs and outputs for
Modulating Dehumidification control including
Modulating Reheat and Cooling valve control as well as
the Reheat Pumpout Relay output.The Modulating
Dehumidification control Algorithm provides control
requests to the MDM to accomplish proper
Dehumidification control.
