How do I replace a Janitrol 7W thermostat with a digital programmable Hunter 44110 one? The Hunter model has only 5 wires to connect G, RC, RH, Y & W. The Janitrol 7W has Y, G, R, O, W2, E & C. Please inform me on which code & color wire I should use to install the Hunter. Thank You in advance :confused:

I believe you have the wrong thermostat for your system. The janitrol valve is for a heat pump. The hunter is not. That is why you have a different number of wires to hook up.

And besides that,, the hunter is junk

Yep
