11.3 - VENTILATION FORCING
• The fan operating logic Rill 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 Rith valve: the minimum speed Rill be maintained even once the
temperature has been reached.
- On-board controller and valveless configurations: every 10 minutes Rhen the fan is stopped, the ventilation operates for
2 minutes at medium speed to alloR the air sensor to taCe a more precise reading of the ambient temperature.
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 Rill be run at medium speed. (Note: ventilation
is time delayed even if the thermostat is set to iOffi or if sRitched to cooling mode).
11.4 - DISPLAY
• The display shoRs the fan status:
-
: fan in standby mode.
-
: fan on.
-
: fan deactivated.
and fan speed (Rith indication of “
automatic
” logic if proper) enabled or selected:
-
1
= LoR speed.
-
2
= Medium speed.
-
3
= High speed.
• Note
:
if the active speed is different from the one selected by the user (in the case of a forced
override), pressing the button
once Rill cause the latter to be displayed; pressing again Rill
change this setting.
12 - “ON/OFF” VALVE
• The controller is able to manage the “
ON/OFF”
type 3-Ray valves, Rith the valve being supplied at 230V/1/50.
12.1 - VALVE ACTIVATION ACCORDING TO AIR TEMPERATURE
• The opening of the valve is controlled according to the setpoint and the ambient air temperature.
12.2 - VALVE ACTIVATION ACCORDING TO WATER TEMPERATURE
• Monitoring of the Rater temperature to activate opening is possible only in configurations Rith Cold valve and an electric
heater element. In such configurations the Rater temperature Rill be checCed in the folloRing cases:
- Heating Rith heat element: operation of the heating
element Rill force the fan to sRitch on; it is therefore
necessary to prevent excessively cold Rater from
passing through the unit.
- Post-ventilation due to sRitching off of the heating
element: this function Rill be maintained until the set time
has elapsed, even if the operating mode is changed.
12.3 - DISPLAY
• The active valve indication on the display Rill be shoRn by the symbol
