Wiring Diagram:
Case Demonstration:
Example 1
Suppose boiler needs to keep the water temperature at 80-90℃
It means stop heating when the water temperature is greater than 90℃, when water temperature down to 80℃, and then start heating.
Detailed settings as follows:
1, Setting stop temperature is 90℃
2, Setting working mode is heating mode "H"
3, Setting hysteresis value is 10 . it means when 90℃ stopping, when the temperature cut down 10℃ and Open heating again.
Example 2
Suppose refrigeratory need to keep temperature at -5℃ to 0℃
It means stop cooling when the temperature is lower than -5℃, when temperature up to 0℃, and then start cooling.
Detailed settings as follows:
1, Setting stop temperature -5℃
2, Setting working mode is cooling mode "C"
3, Setting hysteresis value is 5 . it means when -5℃ stopping, when the temperature up to 0℃ and Open cooling again.
Notice:
1, Please make sure using correct voltage DC 12V.
2, Measuring input is K-type thermocouple, pay attention to distinguish positive and negative, do not use other probes.
3, The output of the relay maximum capacity is 10A, please put control devices's power in series with the output.
4, Need to pay attention to insulation at the bottom of the motherboard when installation.
5, When wiring, disconnect all power to avoid electrical shock hazard.
6, If there is an unknown fault, please restore factory settings.
