Feature: 1. Be able to connect with refrigeration/heating and humidifier/dehumidifier equipment at the same time. 2. HEAT\u0026COOL MODES: Heating/Cooling function could be set separately for refrigeration and heating to protect temperature controller from violent change. Same as humidity Control. 3. MULTI-conservation: temperature calibration-checking and adjusting the accuracy by comparison with the standard value; automatic conservation delay cooling system; and automatic overtemperature alarm. 4. PRECISION CONTROL: scientific layout, best performance; anti-breakdown capacitor ensures safe conservation electric circuit. 5. DUAL DISPLAY: clear and accurate readings, no illegible character. Specification: This digital temperature&humidity controller is perfect for various household, institutional & industrial heating and cooling applications.
