    Bring the Heat

    Moved into an apartment a couple years ago with a intermittent heater thermostat. Dealt with it for too long. Received this new assembly and it works great. Easy to install.

    Time Will Tell

    I bought the Honeywell version of this only 3 years ago. It was smaller and clearner looking but only lasted 3 years. This one is larger , not as stylish and is designed for use on a variety of systems. We have a simple mili volt 2 wire system. I bought it because it was less expensive than another Honeywell. I only hope this one last longer. The old mercury ITT thermostat laster 20+ years.

    Thanks so much

    Save my house and keep it warm temperature. I know had been new Non-programmable Thermostat about 8 or 10 years ago. Its look pretty bad too old and no good for problem change bad temperature damage. Then replace new Non-Programmable Thermostat and now look great much better. I will save two boxes any happen unknow when. Something wrong thermostat and do that replace new that all. Easy idea.

    Look elsewhere for a different thermostat. It works, but it feels cheap compared to others on the market. Slow response time too.

    I have been using several different thermos recently as I am a property manager. Don't like the way it feels or handles. Functional yes, but I'm throwing it away.

    Taking control of the temperature

    Just installed this new digital thermostat replacing a mercury manual unit that came with Williams wall heater. It was east to install. and works great. It's simple to use and I can now see what the area temps are to not over heat the area unnecessarily.

    cozy user the covers

    I manage an apartment building in Los Angeles. And this is the only heater thermostat I will buy for my tenants. Its accurate, dependable, easy to install and reasonably priced.

    Simple thermostat

    This is a very basic thermostat that I needed for a millivolt system. Basically it provides a single switch on/off relay to provide a digital replacement for a 2 wire mercury mechanical thermostat. Working just fine,
