Press Set button again and press Up or Down button to set start up temperature. P1: Press Set button to enter menu, display shows P0. Press Up or Down button till display shows P1, then press Set button again and press Up or Down button to set shut down temperature. P2: Press Set button to enter menu, display shows P0. Press Up or Down button till display shows P2, then press Set button again and press Up or Down button to set calibration temperature. Measured Temperature + Calibrated Temperature=Actual Temperature, for example, if measured temperature is 0.5℃ higher than actual temperature, calibrated temperature should be -0.5℃. P3: Press Set button to enter menu, display shows P0. Press Up or Down button till display shows P3, then press Set button again and press Up or Down button to set delay start time. This function is normally used for compressor refrigeration or refrigerators, you can ignore it if you don't need this function. Package Includes: 1 x Thermostat Note: The input voltage of the AC220V temperature controller can NOT be AC110V. Please make sure your power supply voltage is correct before you buy. Thanks for your understanding.
