WTC100 Wireless Temperature Controller Digital Plug-in Thermostat Outlet Remote Control Heating Cooling Mode for Window A/C Fan Heater Greenhouse Homebrewing Reptile (Built-in Temp Sensor)

I bought this so that I could control two Envi Plug in Wall Heaters. I wanted the heaters because they do not have a fan and I would not have to worry about noise or moving parts. The bad part is that the heaters are do not have a thermostat. The WTC 100 took care of that problem. The remote sensor cycles the heaters on and off resulting in a very even room temperature. Setting things up was a little confusing because it took me a minute to figure out how to pair the socket and the remote. But once I had them paired, the system has worked flawlessly (about three weeks). Overall, a great product!

I have a booster fan on a heating duct in my basement going to my enclosed porch/sunroom where my Bonsai are located. I wanted the booster fan to go on below 60degrees and off above 65degree. I installed two AAA bateries (not supplied) in the remote, changed Celsius to Farenheit, mode was already in HEAT. I set ON to 60degrees and OFF to 65degrees. I plugged the receiver into outlet, then plugged booster fan power cord into receiver. The remote was already paired with receiver. I put the remote with temperature sensor (W100 model) in the porch, testing with window open. As soon temp lowered to 59F, booster fan went on. I moved remote to warm vent air, when temp got to 65F, booster fan turned off. Works great, and now I don't have to run downstairs to switch booster fan on/off, and better than having fan controlled by furnace, because I don't need fan on when the sun warms the porch/sunroom >65F but inside house still needs furnace heat. I had to use a 3-prong outlet extender when plugging in receiver for clearance of outlet switch, just a slight inconvenience. (Receiver covers whole outlet)

It works well besides having to fidget with the temp. It doesn't match my house thermostat temp despite being inches from it.

My ac thermostat failed and it was staying on constantly. Was thinking about spending over $1000 for a new ac. I then found this product! Works great! Highly recommended!

This thing works fine but it has a fatal flaw. There is NO WAY to turn the alarm off permanently. We have it set to control a 400W heater if the temperature falls below the set level. It works great, but the alarm goes off at random intervals until the unit reaches reaches the turn off temperature. The unit usually turns on at night meaning the alarm beeper, which is quite loud, goes off randomly multiple times at night. The manual states that you can mute the beeper by pressing any button when it's going off. That's fine, but that means you can turn it off only after it wakes you up, and it's not a permanent setting. It'll wake you up again to turn if off 20 minutes later.The alarm function turns this from a good design to a design from HELL. DO NOT BUY THIS unless you like being woken up over and over at random intervals during the night.

Makes heat turn on in greenhouse

Works very well and very happy with this but the alarm is sooo annoying!!!!!! Keeps me up and the only way to shut it off is to get up and push a button. Wish there was away to turn this off and keep it off!!!

At this moment I really like it. I hope this working condition will the same in the future.
