1PCS Digital Temperature Controller Microcomputer Controller Temperature Switch Features: 1. The output and input voltage of this thermostat are synchronous, that is to say, when the thermostat is in the working state (the indicator light is on), the direct output voltage is as much as the input voltage. When the temperature controller is in intermittent operation (the indicator light is off), there will be no voltage at the output end. 2. Start temperature<stop temperature=heating mode, for example, start temperature (25 ℃)<stop temperature (30 ℃). 3. Start temperature>stop temperature=refrigeration mode, for example, start temperature (30 ℃)<stop temperature (25 ℃). 4. Setting method: press and hold the up button, the starting temperature flashes, and set the starting temperature value through the up and down buttons. Press and hold the down key again to stop the temperature flashing, and set the stop temperature value through the up and down keys. 5. When setting the heating mode, if the set temperature value is accidentally reversed, the output indicator will not light up and the load will not work. If the above situation occurs after setting, you can check whether the set temperature value is reversed.
