Wiring a 240V baseboard heater T-stat


Hi,

I have a honeywell thermostat for a 240V baseboard heater. The t-stat only has 2 wires so I am confused on how to connect the 2 line wires from the 15 amp panel circuit. All of the instructions I've found for thermostats indicate there are 4 terminals to wire to, which is straitforward. how would I do with only 2 connecting wires?

thank you

Sounds like the "T"stat is 120vac 2 lugs, one LINE and one LOAD switching on HOT . A 240vac has 4 lugs two LINE and two LOAD switching on both HOTS

Wiring a 240V baseboard heater T-stat


Wiring it this way could be dangerous. But I understand it is done all the time and it is safe, as the T-Stat is not the shut off, the breaker is. If this is the case follow these instructions.

Take one one wire of the two hots (supply) for 230 volts. Connect it to one of the T- Stat terminals. If one of the terminals says "line" put it there. Take one of the hot 230 volt wires from the heater and connect it to the remaining terminal. It may say "load"
The last two wires connect together.
The heater cannot operate until the contact closes to make a loop. I hope this type of connection is considered safe, and the manufacturer allows it. Doing it this way will always have one hot wire present at the heater. So never work on any heaters without shutting off the breaker. I do not wire up baseboard heaters in the deep south.
