System wiring description and schematic diagram

1. Three indicators, power indicator and work light (two work lights, one on the board, one external), Power and Work are on at the same time when working normally, and the Work indicator is flashing when it is in the state of stop work or protection
2. Soft Boot This terminal is used to control start/stop. It works when it is closed, and stops when it is disconnected.

Note: There is a short circuit piece on the socket next to the green socket (Soft Boot terminal) at the factory, the socket has the same function as the green socket, if the green socket is used for control, the short circuit piece must be removed, if the short circuit piece is not removed, there is no need to connect the green socket, and the control board will be automatically started when it is powered on.

3. Three-phase electricity A, B, C are 380V power inputs, and OUT1 and OUT2 are output terminals connected to heating coils.
4. When installing, it should be noted that the radiator is not electrified!
5. Coil reference parameters: (Please refer to the comparison table below for details).
