I had a new zoning control board installed last week along with 2 new thermostats so I could see when emer. heat was on and to be able to turn emer. heat on while the unit was running. I keep the heat on 65 at night, it was down to 64 so I turned it up to 66 expecting the emer. heat to come on. It did not turn on so I turned emer. heat on manually (first time I have tried it) and it the system shut off. I turned the Thermostat up to 67 and waited the 5 min. the system requires and it did come on with emergency heat.
Should I have not turned on emer. heat while the system was running or should emer. heat have come on to supplement the system?
The original zoning board was installed 4 years ago, but with thermostats that did not show when emer. heat was on nor gave me the choice of turning the emer. heat on manually. The zoning was done by the same dealer that installed my new 4 ton Trane last Feb. He covered the control board, thermostats and labor under warranty thank goodness.
Thanks,
