LOGICS
FORCED OVERRIDES
The normal fan operating logic will be ignored in particular override situations
that may be necessary to ensure correct control of the temperature or the
unit's operation. This may occur:
in the cooling mode:
> on-board controller (P01 = 0) and configurations with valve: the mini-
G B
mum speed available will be maintained even once the temperature has
been reached.
> on-board controller and valveless configurations: after every 10 minutes
in which the fan remains idle a 2 minute cleaning is carried out at medium
speed to enable the air sensor to read the room temperature more cor-
rectly.
In the heating mode
> while the heating element is on: the fan is forced to run at medium speed
> once the heating element has gone off: a 2 minute post-ventilation cycle
will be run at medium speed. (NB: this cycle will be completed even if the
thermostat is switched off or in the event of a changeover to the cooling
mode)
DISPLAY
The display shows the fan status
>
On flashing: fan in standby mode
>
On steadily lit: fan on
>
OFF: fan disabled to operate by natural convection only
and fan speed (with indication of "automatic" logic if proper) enabled or
selected (in case of stand-by fan)
>
Extra low speed:

Low speed
>
Medium speed
>
High speed
NB: if the active speed is different from the one selected by the user (in the
case of a forced override), pressing the button
the latter to be displayed; pressing again will change this setting.

VALVE
The 230V controller can govern 2 or 3-way On/OFF type valves.
OPENING
The valve opening is controlled according to the operating setpoint and air
temperature setpoint
COOLING
HEATING
WATER CONTROL
The checking of water temperature to enable valve opening is a function that
concerns only configurations with 3-way valves and heating element.
In such configurations the water temperature will be checked in the following
cases:
> Heating with heat element: operation of the heating element will force the
fan to switch on; it is therefore necessary to prevent excessively cold
water from passing through the unit.
> Post-ventilation due to switching off of the heating element: this function
will be maintained until the set time has elapsed, even if the operating
mode is changed. During post-ventilation the water temperature enabling
signal will coincide with the one seen for fan operation.
DISPLAY
The active valve indication on the display will be shown by the symbol
HEATING ELEMENT
The electrical heating element is a device used to provide support where
necessary in the heating mode.(SW water sensor compulsory)
SELECTION
If provided for in the configuration, the heating element can be selected in the
heating mode by pressing the Sel
ACTIVATION
Fan once will cause
If use of the heating element is selected by the user, it will be activated on a call
from the thermostat based on the room temperature
NB: switching it on will force the fan on as well
