FUNCTIONS DESCRIPTION
Through the main switch 11 the panel
board and all the equipments connected
to it will be under power. The switches
12 & 13 switch On and OFF the
power to the burner and the Heating
pump (via a relay, if necessary).With the
thermostat 21 the working temperature
of the boiler can be adjusted. This
thermostat is provided with a DPDT
contact, for the control of a two stage
burner. The differential between the
switching points of the two double pole
is 6°C (not adjustable). The minimum
thermostat, accessible through the
opening of the panel board cover,
switches OFF the C.H. pump during the
reacing of the steady state and up to the
obtention of 50 °C within the boiler. On
the electrical supply line to the boiler a
