Draws up to 3W. Therefore self consumption is excessively high for this type of device. Hysteresis can be adjusted down to 1 degree. (for heating will switch off at set temperature, will switch on 1 degree below set temperature). Can add delay so device doesn't click on-off too often. Needs to stay below set temperature for at least set time (1 minute or more). Will blink WORK led if time has not passed. Will not switch on if temperature rises without activation. After time has passed will switch on immediately if temp goes further than hysteresis allows. OK. Read comments, 230V version might not be absolutely safe.
hello why are you writing with the accuracy of the measurement is 0.1 'C, it is a scam the accuracy of the measurement is 1' C
