KETOTEK Digital Temperature Controller 220V Dual Relay with 2 Sensors Temperature Probes STC-3008 Cooling Heating Controller Incubator

Worked well while it worked but dead after six months! Waste of money, now I need to find a reliable replacement that fits in the same size aperture.

I have used this to control the temperature in a Hotel Swimming pool and it has been doing the job very well up to now.The customer is so happy they have asked me to order another as a spare, which is either this one or the previous one I ordered.It has saved them literally thousands on what another company quoted to do the same job with a bit of reasonably simple design and fabrication on my part.

I built mine into a wooden box with two 13A sockets to control home-brew fermentation (using heater mats). I tape the sensor onto the outside of the carboy, rather than immerse it in the beer.Works a treat and no problems thus far, after a couple of months use.

This unit read in the 50s or 60s and could not be re set. Tried following the instructions but nothing worked. It was 24 degrees and the unit was reading a temperature of 60 degrees. Contacted the manufacturer and followed what they advised but still would not work Had to buy a DD controller in the end.

You can set a cut in temperature and a cut out, e.g. on at 45°C and off at 67°C, separately on the blue channel too. Also swap the cut in and out for cooling. Hopefully it'll last as now controlling my oil fired central heating boiler.

Used to monitor temps of two boxes

Easy to install, I used it to control 19 litre Kettle temperature.

Very handy compact little unit.
