Hi everyone,
I have a Mcquay Thermostat and this is my question. Recently my replace battery light on my thermostat came on, so I did the logical thing and replaced my batteries. The problem though is two minutes later it came back on. I thought that I would have to buy a new thermostat but then I realized that the "C" wire was hooked into it making this a dual powered thermostat. This means it runs off my battery or my electricity.
I was wondering was this always running off my electricity in the first place and the battery was a backup. If this is the case then I do not need to replace it. If it is not the case will this have a big effect on my electric bill if I continue to run it off my electricity instead of the battery?
Thanks for the help.
Yes, I have contacted Mcquay, but no one is in until Monday.
Thanks,
