Solar function
This function is activated automatically id the boiler detects a probe on the DHW inlet (optional) or if the "Solar ignition delay" parame-
ter is more than 0 seconds.
During a withdrawal, if the inlet water is hot enough or if there is "Solar ignition delay" time, the boiler does not switch on, the D.H.W.
withdrawal symbol ( ) appears on the display along with the flashing solar function symbol (
When the water supplied by the solar system is at a temperature lower than what is set, and if the "Solar ignition delay" time has elapsed,
the boiler switches on. At this point, the solar function symbol remains permanently on.
Operation with optional external probe
In the case of a system with an external probe, the boiler flow temperature for central heating is managed by the external probe depending

tons (or on the CAR control panel, if connected to the boiler) selecting a value from "0 to 9".
