System Enabling
(Cont’d.)
Auto
: Conventional System in “Auto-Changeover” mode.
HVAC system will cycle heating and cooling automatically
to stay within preset heating and cooling Setpoints.
Heating
: Conventional System in “Heating-Only” mode.
HVAC system will cycle heating in reference to Heating
Setpoint only. Unit will not activate cooling sequence.
Cooling
: Conventional System in “Cooling-Only” mode.
Setpoint only. Unit will not activate heating sequence.
HVAC system will cycle cooling in reference to Cooling
Off:
HVAC system is inactive.
CCVC
: “Continuous Compressor, Variable Capacity” application in auto-changeover mode.
HVAC system will cycle heating and cooling automatically to stay within preset heating and
cooling setpoints. Compressor will modulate from 100% to 20%, but will not shut off. Typically
used for applications where cycling of compressor is not allowable due to use of on-site generators
– an MRI Mobile Trailer, for instance.
CCFC
: “Continuous Compressor, Full Capacity” Application in auto-changeover mode. HVAC
system will cycle heating and cooling automatically to stay within preset heating and cooling
setpoints. Compressor will not modulate, but will stay at 100% capacity and will not shut off.
Typically, this mode is selected for testing purposes only.
*NOTE
: Upon initial start-up of any system-enable utilizing compressor, the unit may undergo a series of
self-diagnostics, wherein a series of audible “clicks” are heard. This may delay compressor function for
up to 5-minutes.

Cool Setpt / Heat Setpt
are for occupied periods
Cool Setback / Heat Setback
are for unoccupied periods, and will only be used if scheduling
is enabled (see the
Advanced Programming
section)
Min Setpt Diff
is the closest the Heating and Cooling setpoints can come to one another. (3°F
is recommended minimum)
Deadband
is the space in degrees from setpoint in which the Cooling and/or Heating sequence
will modulate to 100% capacity (2°F is recommended minimum).

NOTE
: Although the cooling/heating setpoints can be accessed by simply pressing the arrow keys
during normal operation, any changes made in this fashion will be for a specific length-of-time as an
“override” feature only. This temperature change will not be permanent. See the
Advanced
Programming
section for further information.
