Solar operating mode
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 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
on the external temperature measured (Parag. 1.12). The flow temperature can be modified by selecting the functioning curve via the
knob (6) (or on the CAR
control panel, if connected to the boiler) selecting a value from 0.0 to 9.0.

Preheating function
When the function is active, the word 'BOOST' appears on the display and the boiler is maintained at a temperature sufficient to ensure
instant hot water delivery.
If it is set to AUTO mode (see Parameter t.2), press and hold the MODE button for more than 5 seconds to activate or deactivate it.
In the case of CAR
the activation of BOOST is determined by the programming of DHW bands.

To maintain the temperature the boiler may be switched on even without requests for domestic hot water or central heating; this type of
operation is indicated by the "BOOST" message flashing.
Activating this function leads to a reduction in the energy efficiency of the appliance.
