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.
