Shop name:Chong Qing Shuo Yue Ke Ji You Xian Gong Si 1. Temperature setting (ambient temperature required by the user): the user can adjust it on the thermostat or APP, the adjustment range is -40 to 99.9 Celsius 2. Temperature difference setting: set the difference between the heating and cooling temperature when working at a constant temperature; for example, the temperature is 40 Celsius, the temperature difference is set to 2 Celsius, stop heating after heating to 40 Celsius, and enter the constant temperature mode , When the temperature drops to 38 Celsius, re-enter the heating mode, this value differs by 2 Celsius, this value can be adjusted by the or APP 3. Compressor delay: This function is generally used for compressor refrigeration. If the temperature controller is used for refrigerator freezer, this value must be set. The general setting value is 3-6 minutes according to the back pressure of the compressor. APP to adjust, the adjustment range is 0 to 10 minutes 4. Temperature correction: used to the temperature value currently detected by the thermostat, the correction range is 0 to 10 degrees Celsius Product name: Thermostat Product : DTC1201 supply voltage: AC 110 -230V Temperature range: -40Celsius -99Celsius Temperature measurement accuracy: +/-1Celsius (-40Celsius -70Celsius) Sensor cable length: 100cm Sensor cable type: NTC Size: 93mm x 56mm x 34mm Output capacity: cooling (10A/250VAC) heating (10A/250VAC) Indicator status: Cool indicator (Cool and Heat indicators cannot be on at the time): On: cooling work Off: cooling off Flashing: Press delay Heat indicator: On: heating work Off: heating off Set indicator: On: parameter setting status Data indicator (yellow light: distribution network indicator): Data transmission indicator Net indicator (indicating whether the APP is successfully connected to the device): On: online Blinking: offline Caveat: This thermostat is forbidden to be used in water or excessively humid environment.
