Working Principle

Wiring Diagram

The external power source operates continuously.

When the temperature exceeds the setpoint, Kelvinion & Kelvinion mini automatically disconnect the external power source from the heater.

When the temperature is below the setpoint, Kelvinion & Kelvinion mini keep the external power source connected to the heater and continue heating.
