The solenoid valve opens and closes the hot water circuit via
the summer / winter function of the control unit. If the air
curtain system is in summer or in standstill, the heating circuit
is closed to save energy.
The connection terminals are accessible from the top of the
air curtain system. They are located on the control board.
The clamps are covered with a metal plate. Bend the plate up-
wards on the indicated breaking line and break it off. Proceed
in accordance with the circuit diagram.
An additional connection option is available on the PCB.
These clamps are only accessible inside the air curtain system.
