Had the inside and outside units replaced but using the same thermostat. Since the change out, the blower delay is on the AC cut off instead of the Heat cut off. How do I change it to where the delay cut off is on the heat for the cool down on heater coils.
Do you mean that the blower stays on for a couple of minutes after the compressor switches off? That's the way it's supposed to work. On my unit, there's a separate electronic module wired into the blower control. There's a separate mechanism that keeps the blower working in heating mode: That keeps the blower on until the heat exchanger cools down. (Not a timer.) Your AC technicians probably didn't touch the heater circuit. Perhaps they replaced a broken timer on your AC.
there supposed to do that - but mine what i did was thermo control the power button on the fan power - this saves a huge amount of money - when the compresser part stops - i just shut the whole thing down - saves 35 or more percent doing this - i lived in florida 4 years - its a diffrence of 60 -80 dollars a month running a/c only for 30 -45 min. - then shut down the whole unit - fan too - ha - el cheapo save money o on electrical a/c bill - instead of 210 or more a month - its down to 140 or 150 - presto on el cheapo air o - but you have to be present to do - unless you hook up a timer
This okorder / It all depends on what type of thermostat you have though
