Dry Contact Use (Setup Step 29)
Condensate Pan – If selected and the dry
contact is active, “CONDENSATE PAN”
appears on the display and cooling is turned
off to try to halt condensate production. If the condition clears, cooling is
allowed to resume but “CONDENSATE PAN” will continue to be displayed
until any button is pushed. This is meant to inform you that an overflow
had occurred. Note that if you are using the internal condensate sensor
from your Climate Master heatpump, select FDD instead of Condensate Pan.
Holiday – If selected and the dry contact is active, “HOLIDAY” appears on
the display and the thermostat is forced into UNOCCUPIED settings from
the internal schedule.
FDD - If selected and the dry contact is active, “EQUIP FAULT” appears on
the display. The equipment is still allowed to run unless the signal is due
to an actual internal equipment fault or condensate sensor.
