Call for heat, checking air switch and POC
LED STATE When there is a call for heat, voltage must be detected on
both terminals 12 (PROOF OF CLOSURE INPUT) and
terminal 13 (AIR SWITCH NC INPUT) within 60 seconds.
Failure of either input to prove in time will result in a lockout.
For models with valve proving, both functions are wired in
series to terminal 13.
The air switch check is performed to verify that the air
switch is changing from closed to open (i.e., not jumpered
or stuck) between cycles.
Wire terminal 11 to terminals 12 and/or 13 to bypass
these checks. This works because terminal 11
(ACTUATOR ECONOMY OUTPUT) provides voltage
during this state.
