Comments

M Harrell: I have a Quadra fire pellet stove installed in my home 20+ years ago. My thermostat was at the point where it was unreliable. I saw this one on Amazon and thought I would give it a try. It works great and it keeps my room at the temperature set on the thermostat. The instructions looked more like hieroglyphics! I was able to install this one and I have “zero” electrical skills. My only issue is that my fan runs continuously because when the temperature drops below the set temperature on the thermostat then my pellet stove starts up again and the fan hasn’t shut off from the cooling period of the last heat cycle. I am sure this would be an issue with any thermostat since it is controlled by temperature – a range would be fantastic! I would definitely buy this again, and I recommend it.

Curtis KendrickCurtis Kendrick: My new thermostat works great, and it was easy to install no more guessing what the temperature is. Thanks for making it available.

C.: Nice digital upgrade for the old mercury switch thermostats. Easy to install, accurate, decent cost.

Mark Azali: The box was a bit beat up. I'm not sure if this was a return unit or just suffered a rough transit. My setup is very basic. It's just two wires that start / stop a wall furnace. The temperature reading seems to be accurate.

RC: Our existing thermostat wasn’t working properly. Replaced it with this one. I was even able to change it to Celsius. So far works great.

shiremaidshiremaid: My electrician installed this model with my home rewiring over 8 years ago. It has never failed, I've only replaced the batteries twice. When one of the batteries leaked, I had to buy a new one. I went looking for the exact same model. I found it here on Amazon.ca. (Thank God Emerson kept this model in production after the merge with White Rodgers.)
I love that it shows the temperature in Farenheit. I can see it so easily, thanks to the backlight function (which you have to turn on - thank you to the Amazon customers who gave simple instructions on how to do that!), the display uses large figures, very nice, so easy to install I did it myself, and accurate! I love the accuracy! When the first one had been installed, I had been using a dial thermostat for over 40 years. I was surprised any thermostat could be so accurate. Is it any wonder I went in search of the exact same model?

Stephen Arlaud: I love this heat only thermostat. It is easy to install and instructions are great. Even when the display is not illuminated the display is large and easy to read even for me with bad eyes. The display is so much better then the Honeywell rh110b that it replaces, which has a monochrome like display where the numbers are almost the same shade as the background and does not have a light. This is a perfect choice if you have just two wires, white and red used for forced hot water hydronic heat with an oil boiler. You also have to clip one of the jumpers on the circuit board that makes your boiler react correctly using hot water heat. The construction is also better then the Honeywell and easier to use. This replaces the old round Honeywell that had a twist dial and mercury switch which I used to have some years back.

Update 11/14/19:
I have put in to return this thermostat and get a new one. The flame Icon doesn't turn on when the thermostat calls for heat, it stays on all the time so I don't know if it's defective. I believe it comes on when you select a temp that is higher than the room temp and shows it's talking to boiler to get heat. So I am returning...
