Wiring 220 baseboard heaters newbie

Asked Dec 19, 2005, 08:25 PM — 2 Answers
Hi . I am having probles setting up 2 baseboard heaters in my living room. I have the two of heaters connected and both wires going back to a thermostat box. Any help with how to connect the two heaters to a thermostat. I have a thermostat with a L1 and a t1 marked on them. I took it as L1 to main 220 power. T1 connected to both + wires coming from the baseboards white wires, and the two black wires coming from the baseboard I have connected by a wirenut. The problem is I have heat, but the thermostat is doing nothing. Even when in the off position heater is blasting . Any help with wiring configuration?

May need more details
In 220V wiring, BOTH white and black wires are hot. Each carries current. So, for a switch (thermostat) to work, it must interrupt BOTH lines. You've spliced half the circuit continuous, bypassing the switch.

You may need a thermostat specially made for 220 wiring, I'm not sure on that one.

The only lines that should be wire-nut connected are the neutral, bare copper lines.

I'd shut the power off on that circuit until I had it squared away...

Good luck man,

James


On second thought... Are you sure these are 220V heaters? If they only have two wires and no green or copper, they might not be?

Sounds like your using a single pole tstat, and you need to use a double pole. But the stat you have should trun the heat on and off. Do you have one line (hot) white to L1 and the other two whites from the heaters to T12?

Even thou this should work, I caution you that you must use a double pole thermostat with 240 volt heaters
