hi my problem is i purchased a new dimplex 1500 watt baseboard heater and a honey well thermostat to install. On the switch it only has two wires comming out. In the wall there is a red and black from the fuse box and two wires that go two the heater. So i got four wires in the wall that have to connect to two wires on the thermostat. i tried in series but still get 50volts coming out where the heater is when the switch is off and get 170volts at the heater when i hook it up in parrellel. is this even possible.
