Simple, Inexpensive & Reliable

Would Recommend

I use these in rental units because they are not expensive, they're simple to operate, they need no batteries or C wire, and once installed, I have no repeat calls for service. Very nice piece of equipment that simplifies my life!

RV Replacement Unit. Old School and worked well.

Would Recommend

I used it in a RV Situation. Separate AC and Heater Units. Worked Great where the RV Replacement units (2) that were tried and failed. The old thermostat was from the early 90's and was not made anymore. But this unit hooked up perfectly.
