I installed this thermostat to turn on a fan for our fireplace when the room was up to temperature. It works as described however, as it approaches the temperature to activate the fan it make a high pitched noise as if it is oscillating before it turns on the fan. If there is background noise it may not be detected but it is definitely there. I have written to the company but have not heard back from them.

Works as should

The first one was poorly packaged and came broken. The second one arrived and it's wired backwards. That is to say, it turns off when it gets cool and turns on when it gets warm. This is a cooling thermostat, not a heating thermostat.

First of all - Product shown and described is 803A (Fahrenheit scale) and I received 803C (Celsius scale). I could have lived with this since I had not planned to trust the dial anyway. Installed and found that the set temperature was not even on the scale. I thought maybe it was completely inoperative but connected my meter to it and put in freezer and finally got it to open (dial set to 25C). The thermostat is adjustable by a hex screw under the cover however, and I was able to adjust so that the control temperature was at least on the dial. After testing for a couple days, I have determined that sensitivity is about +/- 5.25 degrees F, or a spread of about 10.5. Would this be acceptable for any application? If used to control an air conditioner even the specification of +/- 3 seems like a lot, but having the house swing from say 60 to 71 is ridiculous. I tried dabbing a little PTFE spray on the adjustment screw contact but this didn't help. Why is such a simple device such a problem? A bi-metal thermostat is not exactly cutting edge technology. Poor quality and obviously no quality testing done at the factory. I don't recommend and will return. Especially annoying as I needed quickly and paid extra for next day. Have an Emerson 16E09-101 on order - more expensive but hopefully will just work.

This is a good general purpose line voltage cooling thermostat. The good news is the deadband. Many of the line voltage thermostats very 8, 10, or more degrees between on and off. I'm using this thermostat to operate an exhaust fan used to cool a small data closet. Temperature control needs to be reasonably tight. This unit lists +/- 3 degrees sensitivity and my experience seems to indicate a deadband of about 4 degrees which is acceptable for what I'm doing. It uses a microswitch with bi-metal actuation and therefore is not affected by orientation (doesn't need to be exactly level). The readout temperature indicator is pretty cheap and I doubt it is very accurate but the setpoint knob seems to be right on. Works well.
