Hi, I am trying to replace a king thermostat that controls two wall heaters with a Honeywell programmable thermostat rlv430, and the instructions make no sense to me. I have 2 sets of wire, both have one white and one black wire, and a ground wire that was connected to the old therm. The new therm. Doesn't have a place for the ground, and the box is plastic. The only way to get it to work is to connect the two whites together, and hook the two black (one on each of the two wires on the new therm.) to the thermo stat.
The ground has no where to go. My problem is I can't get the heat to turn off! It just keeps running and the thermostat will be turned down all the way. Please help, I am electrically challenged to begin with!
