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.
