I would buy this product again!
We were asked to change out 14 line voltage thermostats on a large push boat and picked this item as a replacement. They worked great! The only issue I had is that there was no switching as of Off-Auto-On, Heat/Cool. Otherwise a Great Price and fast delivery!

Worked Perfectly
There is a very dated air coil system in my condo, and this high voltage thermostat was a perfect replacement for the old ones dating back to 1978.

Just what I was looking for.
I needed a line voltage thermostat to control an exhaust fan and this thermostat does the job. My order arrived the day after ordering. No complaints from me, will order again from SupplyHouse.

Perfect for older heating systems
We had been looking all over for thermostats to work with our boiler/chiller system in a 1967 building. Finally, found these and they are perfect!!

Q: How to switch from heating to cooling every season?
Asked by Rob 8 years ago

Verified Reply- Supplyhouse StaffSince this thermostat is non programmable with a mechanical user interface you would have to adjust the temperature manually using the knob.

Q: I have an existing similar one that needs replacement. I have a black hot wire and a white ground wire coming into the thermostat. How does this one hook up and what number of wires does it have?
