As the contact of room thermostat closes, if the mainboard is in winter mode, the system
pump is
only
activated
if the temperature of the primary heat exchanger is higher than the
temperature set by parameter N°6.
If the value of temperature measured by the primary heat exchanger probe is lower than the
programmed delivery setpoint, the triac are ignited in sequence as per the required power.
This occurs only after a settable time by parameter N°5.
The instant power of the boiler and the related control of triac G1-G4 takes place by
means of PID regulator.
