P9: RECOOLING FUNCTION
This function consists in the automatic reduction of the boiler
temperature.
This parameter can be used to set the data relating to the
management of the automatic cooling function of the Boiler. The
activation of the collector pump, for cooling the boiler, will be
indicated on the display with the lighting of both the 'pump' and
'sun' symbols flashing.
The Recooling function will be active if the RCEN parameter is
equal to 1, while it will be disabled if it is equal to 0.
If the parameter is not active in the selected scheme, the display
will show 'NONE'.

ATTENTION
It is not possible to set the value of the 'TR' Recooling
Temperature to a value equal to or lower than that of
the highest Maximum Temperature.
The value of the Recooling Temperature TR is bound to
the value of the highest Maximum Temperature +1 ° C.
If you want to decrease the value of the 'TR' Recooling
Temperature below the value of the Maximum
temperatures set, you must first decrease the value of the
o
r of the maximum temperatures and then act on
'TR' Recooling Temperature.
If any of the Maximum Temperatures is increased to a value
higher than that of the Recooling Temperature
'TR', this is automatically set to the highest maximum
temperature value +1 ° C.
The same considerations apply to the 'TR' Recooling
temperature compared to the 'TAH' Integration temperature.

P10: PERIODIC ACTIVATION OF LOADS
Through this parameter you can manage the periodic activation of the
loads (pumps and valves) present in the selected hydraulic diagram. In
particular, if a load has not been activated for 21 hours, it will be activated
automatically by the control unit for 15 seconds, in accordance with the
operating logic.
If a load activation occurs in this interval, the count will start again from
zero.
The timers that take into account the activation and waiting time will not be
memorized and in the event of a reset or power failure the count will restart
from zero.
The 'periodic activation of loads' function will be active if the PVK
parameter is equal to 1, while it will be disabled if it is equal to 0.
