If HVAC Type is Heat Pump:
Heat Control
Specifies the HVAC control of this thermostat. This parameter describes the thermostat
capability to control a heat pump system. The thermostat can also be disabled from
controlling a heating system and instead operate as a cool-only thermostat. (See Heat
Pump:Cool Control).
Status and Control:
Disable - Specifies that there is no heating system present. (A/C only thermostat.)
Enable - Enables the heat pump as a standard single stage heating system.
Aux(iliary) Heat (default) – Enables control of an auxiliary heat source to supplement the
heat pump heating mode.
Aux Heat Offset
Specifies the auxiliary heat set point temperature referenced to the first stage heat set point
temperature. This parameter is only enabled when Aux Heat is selected, otherwise it is
gray-ed out. (e.g. If the first stage temperature set point is set to 70
were set to -3
Status and Control:
-2 thru -6 – Second stage heat temperature offset from first stage heat set point
temperature.
Cool Control
Specifies the HVAC control of this thermostat. This parameter describes the thermostat
capability to control a heat pump system. The thermostat can also be disabled from
controlling a cooling system and instead operate as a heat-only thermostat. (See Heat
Pump:Heat Control).
Status and Control:
Disable - Specifies that there is no cooling system present. (Heat only thermostat.)
Enable
Compressor Delay
Specifies the minimum time (in minutes) between successive heating, cooling or heat to
cool and cool to heat cycles. This parameter ensures a safe heat pump compressor delay
or off time guaranteed between cycles.
Status and Control:
0 – This enables the cooling system to cycle immediately upon completion of the previous
cycle. This is included as a diagnostic feature and should not be left in this state or
compressor short cycling and subsequent damage may occur to the compressor.
3 thru 10 – Time in minutes required between the completion of a cooling cycle and the next
subsequent cooling cycle. Default delay is 3 minutes.
Reset on Submit
Performs a software reset on the thermostat. All current settings will be maintained after
the execution of this reset. This reset is performed to return the thermostat to a know state
after abnormal behavior. A Proliphix support representative should be consulted
before changing this setting.
Control:
No Action (default) – A software reset will NOT be performed after pressing Submit.
Software Reset – Invokes a software reset after pressing Submit.
