Review on HJ Garden Thermostat Temperature Controller by Yuan Walsh

Needed to control greenhouse fan operation. This mini thermostat has turned out to be quite suitable. In combination with a relay, a timer and a fan speed controller, this mini thermostat works very well. The main meat are short braids; double length recommended. This beef and the temperature readings in Celsius. I could switch to metric if I had 10 years to adapt, but converting Celsius to Fahrenheit is a math problem. Coding becomes child's play with YouToob videos and following an unwritten rule. The temperature sensor reads exactly the same as the MPPT value, also in degrees Celsius.
