Model TC-3: Thermostatically Controlled Outlet - On at 35-Degrees/Off at 45-Degrees

This is a nice product. Just could not work with thermostat heater in bathroom. Did use was electrical heat tape under our camper.

These are great! Make sure you place it where it will be shaded from the sun!During the really cold (below 32) days during 2024 and this year, I had the block heater in my diesel truck plugged in allthe time when I the truck was parked. Now with the wide temperature swings I used one of these units so I could still leave the block heater connected. I also have a small outdoor LED lamp plugged into the outlet so I know when theblock heater is being powered. Several day ago I noticed that the block heater was off, but the outdoor temperature was30 F. I wondered about that and decide to check this out. The sun was out and the outlet was in the sun. I moved theoutlet into a shaded area and the heater came back on after a while. For the price, get two!

fast delivery tested to make sure works and it did.

These work well. Had to take one star off as like others, one of the 4 we ordered failed. Other 3 still working like a champ. Two under the house and one in the pump house. Only comes on when the temps dip down to 34 or 35.Give piece of mind knowing you don't have to remember to turn on the lights for heat should the temps fall below 32 degrees F. These are well made. Just be sure to test them! Short time in the freezer should do the trick.

Love these things! Makes sure our heat lamps come on for the pump, greenhouse and chickens when it's cold. Can get a couple of different temperature settings. I don't have to worry about remembering to turn stuff on when cold. Just have the lights, heater, etc plugged into one of these and it'll be taken care of.

The Farm Innovators TC-3 Cold Weather Thermo Cube Thermostatically Controlled Outlet was supposed to turn on at 35-Degrees F. Last night, 11/19/20, the outside temp dropped below 35 degrees F to 26 degrees F for the first time since purchase. That's 9 degrees F below the advertized "ON temp. I intended to use this to turn on a simple light bulb to protect my wellhead from freezing. (It's what you do here in the south.)EDIT mid NOV 2020: ... Could not find a way to "Contact Seller" on the Amazon site, so, I searched for "Farm Innovators" and found a phone number. I called and reached a customer service rep. I was told that ... "Sometimes the thermostat sticks. Put it in the freezer for 30 minutes and then, quickly, plug a lamp into it and the cube into an outlet to see if the light comes on. Then wait for it to turn off as it warms up." Well, I did this several times and it seems to work now. Seems like this tidbit of information should have been included in the packaging. However, I am sceptical as to whether or not I can trust this thing to work correctly 100% of the time. I will use a "test" lamp in my detached garage for a while to see if it works correctly.Edit 6 DEC 20: Once again the temps outside dipped to 28F and the device still does not work. The "test" lamp in my detached garage did not come on. I purposely set my alarm for 3 AM, the coldest time of the night, to see if the light would come on. I cannot trust this thing to keep the water pipe from my well from freezing. Unless they send me a unit that actually works ... IT'S JUNK!

used under a cattle waterer to keep from freezing. Cube is plugged to a 150 watt ceramic heat bulb and when temps fall below approx. 35 deg. bulb turns on and off at approx. 45 degrees .This area is inclosed approximately 2'x2'x2' so does not take alot to maintain and saves by not having bulb on 24 hrs

I yes this to turn on a tank water heater and a recirculating pump. It works great. It turns on both at about 34F. Keeps the chicken water from freezing.
