Hi all, We recently bought a new house and have been updating all of the baseboard thermostats when I ran into a strange situation Some quick background. I have replaced several old 240v double pole Singer thermostats with new models without issue. All those boxes has 2 sets of wires coming in so it was very straightforward. I now moved my attention to a room with an ancient looking GE thermostat. It is a single pole. It controls 2 baseboards which are 240v and I assum chained together somehow. The surprise was when I pulled the thermostat out and only found 1 set of wires going into the thermostat. I have gotten to the current step in the attached picture. When I try and remove the screw between the wires with the assumption this is how I disconnect them from the thermostats, both heaters kick on. Tightening the screw turns the heaters back off. I would love to switch this setup to double pole. Is that possible? Or is it likely the 2nd 120v hot wire is running directly to the 1st baseboard? The setup just seem strange to me so I was curious if anyone had seen this type of setup before and could describe it to me. Any thoughts or suggestions? Thanks for all your help guys/gals.

I've been reading posts to try and find a problem like ours but couldn't. We just moved in last month and are having problems with the heat and AC. We have a Payne heat Pump, Model PH13NR024.. mfg date was dec 2012 so I assume its 3 years since installed. the thermostat is a honeywell th5220D and the air handler is a Carrier FB4ANF024. the house was a relatives, and they had everything installed around 3 years ago. Shortly after, they became ill and spent their last 2 years in a nursing home. So, the house has sat empty for 2 years at least with only the heat being used in the winter to keep the pipes from bursting. I was told the temp was set on 50. His son said the ac would freeze you out but now it will not even cut on. Here's what it does. When I cut the AC on and set it to a number lower than the current temp.(it was 78 so I set it to 70) The heat pump outside cut on but the blower inside never turned on. I also tried it at a temp closer to the 78. I could heat the thermostat clicking but no blower. If I turn everything off and set just the fan to on, the fan on the blower will not turn on. If I turn on the heat, the outside heat pump will turn on for a couple minutes then switch to aux heat and blower will come on and outside pump will turn off at same time. Its like the fan will only work in aux heat mode and thats the only way we can have heat, which I've read is VERY expensive. I'm new to the heat pump thing but have been reading and learning as much as possible to try and figure this out. To me, it seems like maybe the thermostat or maybe a control board somewhere, maybe in the air handler is mal-functioning, or maybe it was installed wrong in the first place. I've checked all the wires on the thermostat and they're wired as they should be per the manual. We also had someone look at it and they said it was the capacitor at the air handler, so we replaced that. Still no AC or normal heat So, to recap: heat/cool off..fan on-no blower fan cool on...no blower fan but everything is on outside in heatpump and you can hear it pumping freon thru lines heat on...heatpump turns on outside, switches to aux heat then blower comes on and heatpump turns off my background is in electronics so if it involved board swapping or something of that nature, I'd love to be able to save some money here. Any idea where to start?
