Can I use a programmable thermostat as a simple on/off timer at very low ambient temps?
I would like to control a proheat. I have found a few dedicated 12V timers on line, but a I have a spare 7 day timer http://www.kijiji.ca/v-electronics/city-of-toronto/noma-programmable-thermostat/1013787075
I was wondering if I could use it to time my proheat.....
Obviously I can use it to turn on/off the timer at reasonable temperatures, but as the low setting is 55 F., I'm thinking it will turn on anyway as soon as I get it outside in the cold as a default. Most thermostats made for residential have a low setting of 55 which I presume means they kick in no matter what at 55 to avoid freeze damage in the home.
I would like to do this ASAP and I seem to recall someone here saying I could use a thermostat to control a proheat, and I had only just considered the 55 cut in possibility.
BTW if I had a multimeter handy I could double check the low cut in, but I don't, so it is really just a presumption.
