Digital Temperature Controller, Thermostat Outlet Socket, 230 V Digital Thermostat Outlet Plug with Temp Sensor, Temperature Switch Heating Cooling Timer for Greenhouse Farm Aquarium Reptile

Brilliant bit of kit

This is absolutely fantastic at what it does. The thermostat in my freezer failed about 9 months ago and I was unable to source a replacement. I bypassed the thermostat with a spade fuse and bought this, and have been using it ever since to maintain the temperature of my freezer. Since it's a basic freezer and doesn't have any other electrics I've just plugged the original plug into this and bypassed the original thermostat so it works exactly as before. The instructions aren't great but it was incredibly self explanatory to set so not really an issue. I checked the temperature of the freezer using a thermister and can confirm that the temperatures on this controller are reasonably accurate (At least in the -20C region.) Absolute bargain and saved me having to buy a new freezer.

This is pretty good for what you pay with a few caveats:- The instructions are next to useless - for example: "After the start of the machine, relay suction when running to ON, Socket output indicator light, Relay shutdown at Off, Light indicator"- The temperature measurement is not calibrated and not linear - it is possible to adjust the reading by holding "Mode" when you turn the power on - but, because it's not linear, you will find that if you adjust for, say, 0C the reading will be considerably off at higher temperatures.Other things to note are:- The socket can operate a heater or a cooler depending on which way round the "ON" and "OFF" temperatures are set.- There are several modes as well as the basic "on and off" modes, but the instructions are so bad you'll have to experiment with them to see if they work.- My socket worked fine in that the power came on the temperature was less than the "ON" temperature and stayed on until it reached the "OFF" temperature. It continued to work like this when the temperature fell below "ON" again. Some reviewers had problems with this - it's possible they had it in a different mode.Buy this if you want to turn something on when it's "quite cold" and off when it's "warmer" (or vice-versa) but not if you need accuracy over a wide temperature range as it's not accurate enough to allow this.Otherwise, for the price it's not bad.

Excellent bit of kit works really well very pleased with it perfect for my germination light box

I used this initially to control the temperature for new puppies which was essential and kept them just right.I now use it everydayfor controlling room temperature. It keeps the room comfortably warm and is a money saver too! Great investment.

The controller was delivered on 21/1/25 and worked fine at first. However, on 29/1/25, the screen went blank and it just stopped working. I'll put the refund money towards a better controller.

Superb bit of kit for what it cost, use mine as a freezer alarm for the freezer in the garage ,set up in less than a minute, connected an external beacon to warn of temperature drop due to a previous loss of frozen food. recommend 100%

Product works well. Instructions not good but found it easy enough to set by trial and error
