Used in combination with WTS01 for water heater automation. It controls the temperature and depending on my settings, it turns the heater on and off so that I always have hot water at the times I want.

The new model does its job well depending on the sensor you will use ....
Compared to the old one, it is more compact and fits easily into a rail ready, and the contacts are screw-type. Of course, it is good to work with load relays for these

Excellent build quality.

I replaced its software with Tasmota, and in combination with the DS18B20 temperature sensor, it successfully and reliably replaced the old water heater thermostat.
