KETOTEK Digital Thermostat Plug Socket Temperature Controller 220V with Sensor Probe, Thermostatic Plug Heating Cooling for Greenhouse Freezer Refrigerator Fermentation

I use this device to control a heated bench in my greenhouse, it works well, is accurate and is (putting aside the poor instructions) reasonably easy to set up.It is a multi function device and also has the ability to operate as a timer and a controller for a cooling device as well.Do not however get mislead by the statement on the web page that it will automatically switch from heating to cooling.As there is only one socket on the device you can only control a heater or a cooler/fan not both. If you want to control both you need a device like the Rainbird which has two power sockets, one for heating and one for cooling.With this limitation it is a good device and much cheaper than the Rainbird controller. Bye the way the Rainbird is a good device, mine lasted over 6 years before it failed and I bought this KETOTEK to replace it.

I have had this in use for over a year now.It is great at turning the power on and off according to the temperature paramatres you assign.I have set it up, running through a seperate timer socket. The timer socket controls which times of the day it comes on, and during those times the temperature control socket then functions and tells my radiators when to come on and go off.As for how it works, its quite simple (at least the way I am using it). I set a minimum temperature and a maximum temperature I wish the room to reach. When the temperature hits the maximum, it switches off power to the socket and when it hits the minimum temperature it turns the power back on. This is controlled by the temperature probe.This is the only weakness of the device, as the cable is thin and I could see it breaking if you move it around a lot or place it so the wire is kinked. You would be best to consider where in your room would be the best place to monitor the temperature, place the probe and then avoid moving it. This has worked well for me, and as I said it has been in use for over a year now. I occasionally change the temperature settings, but other than that it and the timer plug have just been left to do their jobs with no issues.All in all it has proved to be a good purchase, and at least in my own case has been very reliable.

Does exactly what it should . I found it easy to set up . Used it on 2 occasions for keeping workshop at regular temp while resin cured

Item purchased for a fermentation box. I found the temperature range settings simple to set up and the controller is working as expected. Happy with my purchase and would recommend the item for the purpose I'm using it for.

Excellent, great controls and still working after extended 24/7 use.

Bought this item to use with a tubular heater in my garage, so that it can control the length of time the tubular heater will need to consume electricity. The temperature gauge is very accurate and setting it to come on at a low temperature and go off again when it reaches a chosen higher temperature is a doddle, but I would recommend checking some YouTube tutorials on this specific item, to do this, as the instructions with the instrument are more vague than they need to be. It is very easy to use once you have seen an independent YouTube tutorial, so don’t rely on the English language used with the instructions that come with the item, as they are a little clumsy. For added interest, the tubular heater and this temperature controlled plug have been purchased to complement my solar panel battery backup system, to ensure that my solar panel batteries don’t fall below zero degrees centigrade in the winter - as they won’t re-charge if that happens.

Very handy little unit, only used for a month but worked continuously…

Works well for heating or cooling
