cut off thermostat has two different modes. First cut off thermostat in cooling mode: When the measured temperature is higher than or equal to the set value + hysteresis when, relay, start output; When the measured temperature is lower than the set value, the relay off, turn off the output. Next is cut off thermostat in heating mode: When the measured temperature is higher than or equal to the set value, the relay off, turn off the output; When the measured temperature is lower than the set value - hysteresis, the relay starts output.
