signal shall be considered valid if the compressor output is energized and the defrost signal has been active for less than 15 consecutive minutes. Any defrost signal present for longer than 15 minutes shall be considered invalid.

Heat pump/fan coil and hybrid heat systems shall use this input to:

SDetect that defrost is in progress and energize the auxiliary heat to provide homeowner comfort during the defrost cycle

SAllow a defrost cycle to run to completion regardless of the system demand

Three-Minute Minimum on Time

In normal operation, when a stage turns on, it will not turn off for a minimum of 3 minutes. If the setpoint is changed, this timer is canceled, allowing the equipment to turn off immediately when the demand is removed.

Heat/Cool Setpoints (Desired Temperature)

A minimum difference of 1_F and maximum of 6_F 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.
