4.5" Display Conventional Non-Programmable Thermostat 1 Heat/1 Cool

The installation process of the thermostat was very easy and self explanatory. The unit also mounted to the wall very easily too. All to say though, the product works extremely efficiently, so much better then the older, obsolete unit I was trying to buy again. I am so grateful that the old unit was no longer available. The wall unit is very attractive to look at and very easy to use too. This has great performance as far as I am concerned. I hope this will put others at ease when trying to decide on a good product.

Used with a geothermal furnace. Unit was set as directed in installation instructions. A geothermal unit requires a signal to the Y and G terminals. Instead the unit sent signals to the W and G terminals with a call for heat. With a call for cooling it sent the correct signals to Y, O/B., and G. I contacted Supply House who gave great service and sent a replacement; however, It also did the same. The problem was solved by placing a jumper between terminals Y and W. It a good unit and with the modifications works great, but it should be taken off the market until it is properly wired.
