Tau Flow Ex s This parameter is only available for constant flow units with control on both flows (Factory menu). (default 030) It
is the value of the integral time relevant to the return flow.
Kp Flow
This parameter is only available for constant pressure units with control on one flow (Factory menu). (default 040)
It is the value of the proportional coefficient relevant to the detected flow.
Tau Flow sec This parameter is only available for constant pressure units with control on one flow (Factory menu). (default 030)
It is the value of the integral time relevant to the detected flow.
Adjust zero
Dp\Flow
The pressure sensor can be reset through this parameter. This operation must be carried out when the fans are
off, and it is preferable to carry it out on a regular basis to correct any reading errors.

150%
This parameter is available if the control is set to run variable speed fans (Factory menu). Default value 100%, it
expresses, in a percentage format, the desired ratio between the exhaust fan speed and the input fan speed
that generates an imbalance between the air flows. The maximum speed that can be set in the main window
will always be 100%, what changes is the minimum speed value that can be set by the final user (see Max.
speed).
Valv. sec
60->600
This parameter is available if the control is set to run a modulated water-based post heating/cooling system.
Default value 120, it is expressed in seconds; it indicates the opening/closing time of the solenoid valve 3 points,
it is adjustable in 10-second steps.
Pir.Min
001->240
This parameter is available if one digital input is configured at the PIR value (presence detector, see Factory
menu). Default value 10, it is expressed in minutes; it is the time during which the fans run at the maximum speed
after the pulse (closing of a NO contact) from a presence detector. After this lapse, the fans will return to run at
the speed set from the control panel until the pulse from the presence detector is lost; since now on, the fans will
run at the minimum speed.
Boost min
001->240
This parameter is available if one digital input is configured at the booster value (Factory menu) Default value 10,
is expressed in minutes; after the pulse from an external contact (closing of a NO contact) the fans run at the
maximum speed (booster). When the pulse from the external contact is lost (external contact open), the fans
keep running at the maximum speed for the time fixed by this parameter. When the booster function is off, the
fans run at the speed set on the control panel.
Booster
Dehum.DTd
-002->-020
This parameter is available if Dehumid.AI is configured as AI1 \ AI2 from factory menu (dehumidification
enabled). Default value is 12 expressed in °C. It represents the differential, respect to the return temperature, to
which the control will refer to adjust the valve installed on the cold side. For example, if Tr is 22 C° and the differen-
tial is 12, the control will adjust the valve so that ,the temperature detected from the probe after the cold water
coil (Td) is around 10 C°.
