Electric Baseboard Heaters and Thermostat
I have 6 electric 220V heaters powered by two separate 20A circuits. All heaters are wired to a single thermostat. The thermostat is labeled 24V, and only has a small red and white wire running to it (far smaller than 10# or 12# wire.) I would like to replace this thermostat with a progammable. Originally, I bought a programmable thermostat for line voltage, but that appears not to be the correct option. Then I bought a standard Honeywell thermostat (RTH6300B,) and hooked that up. Now only one half of my living room heat (1 breaker worth) works. I'm assuming that somewhere in my wall, I have a 220V/24V relay (or two,) but I have no idea where. So my question is: why is this not working? Do I have the wrong thermostat (again?) Does this little battery powered thermostat not provide enough power to flip these 24V relays (if they exist?) Also, the old thermostat had a little green light that would light up when the room was dark, so I know the little red and white wires must be carrying some power from somewhere... This appears to be a pretty good one! Thanks for any help!
