- 1). Turn the power to the electrical circuit off by turning off the correct breaker in the circuit breaker panel. Use a multimeter to confirm that the power is off.
- 2). Wrap electrical tape around the two white wires in the electrical box. Doing this signifies them as hot and not neutral because the two pole thermostat will be wired for 220 volts.
- 3). Connect the black wire coming from the circuit breaker panel to one of the top terminals on the thermostat. Connect the white wire coming from the circuit breaker panel to the other top terminal on the thermostat.
- 4). Connect the black wire coming from the electric heater to one of the bottom terminals on the thermostat. Connect the white wire coming from the electric heater to the other bottom terminal on the thermostat.
- 5). Connect the two ground wires plus a short piece of wire together in a wire nut. Take the other end of the short wire and connect it to the ground terminal on the thermostat.
- 6). Push the wires into the electrical box gently and secure the thermostat to the box with screws.
- 7). Put the cover plate over the thermostat. Proceed to wire the heater into the circuit.
- 8). Locate the two heater wires. Connect the black wire to one of the heater wires and the white wire to the other heater wire. Use wire nuts for these connections. Connect the ground wire to the grounding screw on the heater.
- 9). Turn the power on to the circuit and set your thermostat at the desired setting.
