The main switch 11 powers the board and the equipment
connected to it.
The switches 12 and 13 in turn cut power to the burner and to
the system pump.
The thermostat 32 adjusts the working temperature of the
boiler.
The working thermostat is provided with two switching con-
tacts to control the two-stage burners.
The differential between the two contacts is 6°C (not adjusta-
ble).
The minimum thermostat, which can only be accessed after
having lifted the cover of the electric control board, stops the
system pump until the boiler reaches the temperature of 50°C.
The electric power line of the boiler's control board must have
a switch with protective fuses.
For use of the panel board, see the system manager instruction booklet
