Circuit connection: The reference circuit diagram is connected to the power supply and load. If the temperature sensor is missing or damaged, the digital tube will display “- - -”. The buyer must check whether the temperature sensor is installed before use.
The temperature control output is a 10A relay to meet various high power loads, please ensure that the line is correct.
Indicator light, digital tube status description:
Indicator light: Off means the relay is off, steady light means the relay is closed
Digital tube: display "- - -", 1, check the temperature sensor is missing or damaged 2, heating mode high temperature protection 3, cooling mode low temperature protection. The relay is automatically disconnected in the protection mode.
Use of buttons: The thermostat panel has three buttons, button + button - setting button SET
Press +: to achieve rapid accumulation of values
Button -: Realize rapid decrement of values
Set the key SET:
SET long press Enter the temperature difference setting interface. At this time, the temperature difference can be adjusted by pressing the button plus or minus. After the setting is completed, press SET or wait for 10S, the system will automatically exit the setting data.
Set the temperature difference ≥ 0, for example, set the temperature difference is 5 degrees, indicating that the upper limit temperature - lower limit temperature ≥ 5, the relay working state is closed, the upper limit temperature - lower limit temperature < 5, the working state is open.
Set the temperature difference <0, for example, set the temperature difference to -5 degrees, indicating that the lower limit temperature - the upper limit temperature is ≥ 5, the relay working state is closed, the lower limit temperature - the upper limit temperature is < 5, and the working state is off.
