Auto
With this parameter, you can configure a device that automatically adjusts the fan speed. See the wiring diagram
for the connection of the device.
External
signal
The fan speed will be controlled through an external 0-10V analog signal (default value); if the ex-
ternal signal takes the 0V value, the control will indicate a problem with the source of the external
signal.
AutoMin%
Corresponds to the input signal percentage value for which fans must run at the minimum speed.
AutoMax%
corresponds to the input signal percentage value for which fans must run at the maximum speed.
SP.1,2% SP.2,3% and Δ values depend on the values of parameters AutoMin% and AutoMax%
according to the following formulas:
RH sensor
The fan speed will be controlled by a relative humidity (RH) sensor with 0-10V output and will have
a linear trend between 0 and 100% RH (0V corresponds to 0% RH and 10V corresponds to 100%
RH); if the external signal of the RH sensor takes the 0V value, the control will display a problem
with the sensor.
See graphs of the segnale es parameter.
In this case,
AutoMin%
corresponds to the relative humidity value for which the air quality is held
to be excellent,
AutoMax%
corresponds to the relative humidity value for which the air quality is
held to be very bad.
CO
2
VOC
The fan speed will be controlled by a CO
2
(or CO
2
-VOC) sensor with a 0-10V output and will have a
linear trend between 0 and 2000 ppm (0V corresponds to 0% ppm and 10V corresponds to 2000
ppm); if the external signal of the CO
2
sensor takes the 0V value, the control will display a problem
with the sensor.
Where
AutoMin ppm
corresponds to the CO
2
(CO
2
-VOC) concentration for which the air quality is
held to be excellent,
AutoMax ppm
corresponds to the CO
2
(CO
2
-VOC) concentration for which
the air quality is held to be very bad.
SP.1,2% SP.2,3% and Δ values depend on the values of both parameters
AutoMin ppm
and
AutoMax ppm
according to the following formulas:
none
(Default value) no device is installed for the automatic operation of the fan speed.
AutoMin%
This parameter is only available if the auto parameter is set on ext. signal or UR sensor. It can take values between
0 and 99% (1% steps) with the following limit: AutoMin%<AutoMax%
For a unit equipped with variable speed fans:
If auto ext. signal
corresponds to the input signal percentage value for which fans turn at the minimum speed; below
this value, fans remain set at the minimum speed. For instance, the value AutoMin% 030 corres-
ponds to a 3V (30% of 10V) input signal.
If auto UR sensor
corresponds to the (percentage) relative humidity for which fans turn at the minimum speed; below
this value, fans remain set at the minimum speed.
