Temperature controlled relay 12V - W1209

This temperature-controlled relay that, as the name suggests, contains a relay that is activated at a preset temperature. The supplied probe, which contains an accurate thermistor, measures the current temperature with an interval of 2Hz. When this temperature is higher or lower than the set temperature, the relay will start. The relay can switch up to 20A!Settings (press and hold SET):P0: Trigger below or above a certain temperature (Cooling / Heating)P1: The number of degrees Celsius between the set temperature and the activation of the relay.P2: Maximum temperatureP3: Minimum temperatureP4: Temperature correction / calibrationP5: Start delay 0 - 10 minutes
