Hello,
I'm new to this board. I did search for an answer, but could not find any existing topic which covers my situation. I'm looking for someone who may be able to shed some light on my problem.
I have a 9-year-old HAI OmniPro-II system, coupled with a 4-zone set of HAI Omnistat RC-122 Thermostats. Late last night, my family awoke to very cold air throughout the home. All 4 thermostats were in a nonstop "cool" mode. All 4 thermostats read "27" where the current room temperature would normally appear. The only thing I could do to stop the cooling was to turn each unit into "OFF" mode. The Dealer Access software shows that the status of each thermostat reads back a current temperature value = 0 (which I'm guessing means that no value is being returned to the automation system).
I have gone back through installation diagnostics on a few of the thermostat units. I don't see any problems with the setup. I have disconnected the thermostats from the main Omnistat-II controller (making each thermostat totally independent). Nothing I have done will eliminate the errant "27" reading.
How could all of the thermostats have gone crazy at one time? ... Why is it that I cannot get them to operate properly even when I disconnect them from the HAI home automation system?
We have a cold front headed our way tomorrow ... Any guidance would be most appreciated.
