Any Electricians in The House?: Installing Thermostats
Hi guys. I’m looking for some help and advice from those goodjers who are electrically inclined.
I’m trying to install programmable thermostats in my house for my baseboard heaters, and ran into some problems with the wiring. I seem to have two different wiring setups in the house for the baseboard heaters. All the heaters downstairs (3 in total) are on the one circuit breaker , while the kitchen and living room upstairs share one breaker, and the two upstairs bedrooms are on another.
When I took the original thermostats off the wall downstairs and looked inside, I saw four wires coming from the wall: 2 red and 2 black. The original thermostats had 4 wires as well: 2 red and 2 black. The wiring was setup so that 1 red from the wall went to 1 red on the thermostat, 1 red from the wall went to 1 black on thermostat, 1 black from the wall went to 1 black on the thermostat, and 1 black from the wall went to 1 red on the thermostat. The trouble I am having downstairs is that the programmable thermostats only have 2 black wires coming out them. The instruction manual for the programmable thermostats has a diagram that seems to indicate that I should splice two wires from the wall together, then put the other two into the thermostat. While I am not 100% naive in electricity, I am a little leery of doing this based on my limited experience. Any thoughts on how I might wire up the programmable thermostat?
