Heat/Cool Setpoints (Desired Temperature); Equipment On Indicators; Humidify And Dehumidify Indicators; Auto Changeover - Carrier Performance TP-PRH-A Installation Instructions Manual

Heat/Cool Setpoints (Desired Temperature)

A minimum difference of 1_ and maximum of 6_ is enforced between heating and
cooling desired temperatures. This is done by allowing 1 setting to "push" the other,
to maintain this difference. This difference is adjustable via Configuration Option
11.

Equipment On Indicators

When cooling equipment is on, a COOL ON icon is displayed. While cooling
equipment operation is delayed by the time guard or cycle timer, COOL ON will
flash. The same is true for HEAT ON icon.
During second stage compressor operation a "2" will be displayed with the HEAT
ON or COOL ON icon. This is displayed when the Thermidistat Control is
configured as H2, A2, or h2.
When the W is energized in a heat pump or Hybrid Heat system, the "auxiliary heat
on" icon will be displayed.

Humidify and Dehumidify Indicators

When the Display Module door is closed, the humidify icon will be displayed when
humidification is active and the dehumidify icon will be displayed when
dehumidification is active.

Auto Changeover

When auto changeover mode is selected, a change from heat to cool (or vice versa)
will not occur until an opposite mode demand has existed for 20 minutes. If setpoint
is changed, 20- - minute requirement is deleted.
Emergency Heat Mode
When Thermidistat Control is configured as a heat pump and emergency heat is
selected, all Y signals are locked out, and W becomes energized upon a call for
heat.
