QUICK START PROGRAMMING
• 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. HVAC system will cycle cooling in
reference to cooling setpoint only. Unit will not
activate heating sequence.
• 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
such as an MRI mobile trailer where cycling
of compressor is not allowable due to use of
onsite generators.
• 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 foer 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.
