3 Window Display Temperature Controller -19-99℃ Thermostat Module for Air Conditioning Systems220V Item Type: Temperature Controller Module Material: ABS, stainless steel Uses: Widely used in the field of incubation, equipment chassis, air conditioning systems, temperature control protection and other fields Humidity Measurement Range: -55-120℃ Temperature Measurement Accuracy: ±0.3℃ Temperature Control Range: -19-99℃ Control Accuracy: 1℃ Moisture Measuring Probe: NTC10K/B3950 (standard 1 meter waterproof probe) Display Color: Yellow+Red Applicable Environment: -25-55℃/humidity 20%-85%RH (non-condensing) Output Type: 10A relay output Panel Size: Approx. 90 x 60mm/3.5 x 2.4in Start temperature <stop temperature = heating mode Setting Method: Set the start temperature to 45℃, and the stop temperature to 60℃, such as start temperature>stop temperature=cooling mode Setting method: Set the start temperature to 35℃ and the stop temperature to 32℃ Function Switching/Switching Machine: 1. In the power-on state, press and hold the SET button for 3 seconds to turn on and off the machine. 2. In the shutdown state, press the SET button to turn on the phone. If the power is off after the power is turned on, the power will remain on when it is turned on again 3. During normal use, press the SET button to perform F-1 (intermittent work), F-2 (time off), F-3 (time on). 4. Function switching (F1-F3 are additional functions used, and have nothing to do with the setting of temperature control, and can be used without it) Features : F1: Intermittent work, start minute setting on the left, stop minute setting on the right F2: Timed shutdown, hour on the left and minute on the right, maximum 99 hours and 59 minutes can be set F3: Timing power-on, hour on the left and minute on the right, maximum 99 hours and 59 minutes can be set Temperature correction: Unplug the thermostat, press and hold the SET button to power on, enter the temperature correction function, the screen displays --000-, you can add or subtract the temperature based on the temperature before the correction. Maximum range -9.9C-99℃, after calibration, real-time temperature = temperature value before calibration + calibration value Self-Check Function: At the same time, press and hold the start temperature setting button on the left, and then power on to enter the self-check function. Reset: At the same time, press and hold the right side to stop the temperature setting button, then power on, the screen displays 88-888-88, the buzzer beeps once, and the factory reset is completed.
