Rated 1 out of 5 by Nice looking thermostat, but after installing it, Ihad to replace it with a different one two days later. Twice, this thermostat got stuck. It turned the furnace on like it was supposed to, but on two nights it failed to turn the furnace off when it reached 68 degrees. The first night, the furnace stayed on continuously until I shut off the power when the room temp reached 75 degrees. The second night, I returned home from work to find the room temp at 80 degrees while the furnace was still running. This new thermostat was still set at 67-68 degrees. Before I had this problem, I had discarded the product box, but saved the lable. I will be seeking to return this for a refund, as it proved to be unreliable. April 28, 2014

Hello, Grainger!

Could you please provide the installation manual for the thermostat or a good explanation or wiring?

What do Terminal Designations RH, RC, Y, W, G mean?

I had a normal single-relay thermostat installed before, with COM for line voltage, NO - heating on, NC - heating off.

How does it refer to RH, RC, Y, W, G?

Please kindly advise me

Many thanks,
