I want to replace my thermostats for my 110V electric heat. individual per room. Old one's are the round knob looking ones. So i open up the guy and take a peek at the wires and that's where i have the problem. there are 2 blk, (twisted together) 2 white (twisted together), a single black and a single white. Total of 6 wires (4 if you count the twisted ones as one), the programmable thermostat....only has 2 blk.
Only one lowes carries / says its for 110 electric / house is relatively new...3 yrs old.
