Hi,
I just purchased a NOMA 5+1+1 thermostat. After replacing the old thermostat, the furnace stilll works. The problem is my furnace has a 4 speed fan blower motor. It is wired to permanenlty run the fan on low speed. With my previous thermostat, when the heat came on, after the furnace warmed up (matbe 10 minute) the fan would switch to medium speed until the set point was reached.
With the new thermostat, the motor does not seem to do this (it just stays on low speed). Consequently, it takes over an hour to bring the house up to temperature, were before it would take only 15 or 20 minutes.
I have matched the wiring from the old thermostsat to the new (ie G to G, Y to W, etc.) Is something wrong or is the fan supposed to stay on low speed?
