Description
The boiler has electronic timing, which prevents the burner from
igniting too often in central heating mode (with step of 10)
In the ignition phase, the boiler performs an ignition ramp in order
to arrive at the maximum power set (with step of 10)
The boiler is set to switch-on immediately after a request. In the case
of particular systems (e.g. area systems with motorised thermostatic
valves etc.) it could be necessary to delay switch-on (with 10 step)
