There's 1 relays on this controller. Refrigeration and heating mode can be set through the menu. Can be used for domestic freezer, water tanks, refrigerator, industrial chiller, boiler, steamer, industrial equipments and other temperature-controlled systems.
For example, If you choose Heat mode(Set P0 to H). Set Temperature Value to 30degC. Set P1 value to 0.5 degC.
The relay will be connected when the temperature drop to 30 degC. And the relay will be disconnected when the temperature reaches 30.5 degC.
If you choose Cool mode(Set P0 to C). Set Temperature Value to 30 degC. Set P1 value to 0.5 degC.
The relay will be connected when the temperature reaches 30 degC. And the relay will be disconnected when the temperature drops to 29.5 degC.
