Electric baseboard thermostat problem.
 

Hello,

I've recently replaced the thermostat to a bathroom electric baseboard unit. When taking the old thermostat out, I 'thought' I had installed the wires the same way but blew the main breaker.. opps!

This is what I have:
from the wall I have one black and one white wire that belong to the baseboard unit. Then I have two connected black wires and two connected white wires.
I'm trying to install a basic Honeywell dial thermostat. On the back of the thermostat I have two black wires labeled L1 and T1 and two red wires labeled L2 and T2.

Can anyone help install this properly?
Thank you.

Is this a 240 volt heater (double pole breaker that tripped)?

Yes it is a 240v heater. And I actually popped the main breaker for my condo.

Yea, I just realized you had said Main.
If you could post a pic, that would really help cause I'm kinda lost on the part where you say "Then I have two connected black wires and two connected white wires."

This is what I have.

So the two wires on the right went to the heater and the heater is 240 Volt?
If this is the case then the white wire on the right should have 120 Volts and should have had black tape wrapped around it to indicate that it's hot not neutral. How about a pic of the connection points to the heater and the thermostat?
I just want to be sure what your looking at before telling you how to hook it up.

single Black from box to L1 of stat. single white in box to T1 on stat. cap off the two reds separately. If its wired the way i think it is at the baseboard unit, then this will work. Later Paul

Actually, I was thinking black wire to L1 of the stat, white wire to L2 of the stat and T1 & T2 to the baseboard heater. However, I want to make sure what he has before we do anything.

I would say by looking at his box that they run 220 to the box black and white, and the run that 220 to the baseboard which would be the other black and white that are tied together and then they wired a cable black and white back to the box to break one line through the stat. alot of guys do it this way. There would not be any neutral wires there. paul

Hey guys thanks for all the help.

Just for more clarification. There are three heater units all with their own thermostat wired to one breaker.

In the picture the white and black on the right are dead and go to the heater.
The wires on the left: two go to the next heater on the floor and are dead. And the other two most likely come from the first heater and are hot.
(breaker is off)

Here is the back of the thermostat.
