Digital Dual Temperature Controller 220V Heating Cooling with 2 NTC Waterproof Probes Sensors, Thermostat Temperature Switch for Aquarium Freezer Fridge Fish Tank Heater Cooler

This is exactly what it says on the tin. It has been controlling the temp in my fish pond now for over 2 years without issue. Inexpensive and no frills but perfectly adequate for the application. I would recommend this item

Works as it claims. Brilliant bit of kit.I used it in a biltong box to keep the air flow on a cooler fan and a heater at the right temperature. Took a while to sus it out as the instructions are not great. When you sus it it works brilliantly.

Shows 3 degrees lower than our other original quality thermometers.

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.

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.

Very handy compact little unit.

Nice tidy stat
