Hi, I'm replacing my old in-line thermostat with a Honeywell CT 410. The old 4-wire thermostat is connected as follows: I have a single black wire going to a red line and a single white wire going to the other red input. Also, two black wires are connected to one black in-put and 2 white wires going to the other black thermostat in-put. How should I wire it with the new 4 wire thermostat (L1-red, T1-red, L2-black and T2-black wires)?
Many thanks
