WATER CONTROL
Irrespective of the type of fan present (modulating or non-
modulating), fan operation will be constrained by the system
water temperature control. Based on the operation mode, dif-
ferent heating or cooling thresholds will be enabled.

Upon a call of the thermostat, the absence of the enabling

The enabling signal is ignored:

FORCED OVERRIDES
The normal fan operating logic (modulating or non-modulating)
will be ignored in particular override situations that may be
necessary to ensure correct control of the temperature or the
unit operation. This may occur:
in the cooling mode:
o n-board controller (P01 = 0) and configurations with valve:
the minimum speed available will be maintained even once
the temperature has been reached.
Room
o n-board controller and valveless configurations: after
temperature
every 10 minutes in which the fan remains idle a 2 minute
fan rotation is carried out at medium speed to enable the
air sensor to read the room temperature more correctly.
In the heating mode
w hile the heating element is on: the fan is forced to run at
medium speed.
o nce the heating element has gone off: a 2 minute
post-ventilation cycle will be run at medium speed.
(N.B.: this cycle will be completed even if the thermostat
is switched off or in the event of a changeover to the cool-
ing mode).
