Hey all,
I had 7 thermostats and could get all but two wired. You think I have a chance to find a digital thermostat that can be wired this way? They did these two with some kind of funky wiring. Ill be contacting some manufacturers but just wanted to see if anyone has ever seen this. I was able to rewire all the other to the normal Line/Load scenario.
 
Not clear on the funky wiring. Are these two relays feed from a combination 240 to 24 volt transformer and built in relay ? Have used these transformer relay combinations control to power a 24 volt programmable wall thermostat to control baseboard heaters. Good thing about the 24 volt thermostats they are more accurate then the typical single or two pole 240 volt line thermostats.

I am assuming you maybe wanting to replace existing mechanical thermostat with a digital thermostat and you ended up having two were only switching a single line? This would be greater possibility of encountering if it is a single pole thermostat.

Might be physically possible to have a two lead digital thermostat but I am not aware of any that actually are like that.

Not aware of any digital line voltage electric heat thermostats. How about some manufacturer and numbers for the ones you are talking about?

Please clarify who you are asking and what you are asking about. Surely you have seen digital line voltage electric heat thermostats before.

I don't know if they exist or not, was just saying it maybe could be possible but have never seen one. Would be sort of like how two wire electronic timers, occupancy sensors, etc. function if they would do it.
