1dL
IdL = Idle, no demand for cooling, heating, or fan
Ht1 = Demand for 1st stage gas heat (HT = S8B1 / S8X1)
Ht2 = Demand for 2nd gas heat
CL1 = Demand for 1st stage cooling (CP1 = S8B1 / S8X1)
CL2 = Demand for 2nd stage cooling (CP2 = S8X1)
HP1 = Demand for 1st stage gas heat pump (CP1 = S8B1 / S8X1)
HP2 = Demand for 2nd stage heat pump (CP2 = S8X1)
COf = Demand for continuous fan
dFt = Demand for outdoor unit defrost, furnace running in gas heat mode
tP1-9 = Tap selected for airflow
Note:
1. The menu status displayed is solely dependent on the input of
24VAC that is applied to the low voltage terminal strip.
2. The status will alternate between the system mode and the airflow
request every 2 seconds.
3. If an error occures, an E*.* will alternately flash with the system
mode and airflow request. See first example.
