AutoOff ppm
This parameter is only available if the auto parameter is set on CO
2
VOC and the digital output is configured as
auto cmp.
0000
ĺ
2000
Default value 0500, it is expressed in ppm; for higher values of ppm as read by the CO
2
probe than
the set one, the digital output returns to its standard status.
By-pass
Tmin
This parameter is on if the control is configured for the control of the by-pass (Factory menu)
12
ĺ
18
Default value 15, it is expressed in degrees centigrade. It is the minimum temperature value (T min)
the system will refer to for the control of the by-pass if By-pass automat. or Stagione non def. are
set in the Parameters menu (see Parameters menu).
By-pass
Tmax
This parameter is on if the control is configured for the running of the by-pass (Factory menu).
20
ĺ
30
Default value 22, it is expressed in degrees centigrade. It is the maximum temperature value (T max)
the system will refer to for the control of the by-pass if By-pass automat. or Stagione non def. are
set in the Parameters menu (see Parameters menu).
Filter hours
This parameter is on when the clogged filters alarm is based on the hours of operation of the unit (Factory menu)
00000
ĺ
99999
Default value 02000, it is expressed in hours. It represents the number of operation hours of the unit
after which the clogged filters alarm is triggered. In order to reset the alarm, the installer will have
to set the new limit at which the alarm must be signaled (check the current operation hours in the
parameters status menu Fan hours):
Filters hours = Fan hours + hours for a new alarm
Max speed
This parameter is available if the control is set to run variable speed fans (Factory menu)
055%
ĺ
100%
Default value 100%, it is the maximum fan speed expressed as a percentage of the nominal value
(reduction of the maximum speed).
The maximum speed that can be set in the main window will always be 100% also for Vel.max va-
lues lower than 100%; what changes is the minimum speed value that can be set by the final user:
Minimum speed =INTECCESSO ((VMIN×100)/(VMAX×step))×step
{(VMAX=(Max speed ×VE)/100 se VE≤100
{VMAX=(Max speed ×100)/VE se VE>100
VE= percentage of exhaust fan speed vs input fan (see next paragraph)
INTECCESSO = rounds up to the next integer
VMIN = minimum speed set in the Factory menu
step = discrete values of the speed values that can be set (5%, it can be set at 1% on specific
request, Factory menu)
Press. Max
This parameter is only available for units with constant pressure (Factory menu)
1000Pa
Dpexhau.
= XXX%
Dpsupply
This parameter is only available for constant pressure units with control on both flows (Factory menu).
074%
ĺ
135%
Default value 100%, expresses, as a percentage, the desired ratio between the exhaust fan pres-
sure and the supply fan pressure, which creates an imbalance between the pressures of both flows.
Kp Dps
This parameter is only available for constant pressure units with control on both flows (Factory menu).
040
It is the value of the proportional coefficient relevant to the input flow.
Tau DpS
sec.
This parameter is only available for constant pressure units with control on both flows (Factory menu).
030
It is the value of the integral time relevant to the input flow.
Kp DpE
This parameter is only available for units constant pressure with control on both flows (Factory menu).
040
It is the value of the proportional coefficient relevant to the return flow.
Tau DpE sec.
This parameter is only available for constant pressure units with control on both flows (Factory menu).
030
It is the value of the integral time relevant to the return flow.
Kp Dp
This parameter is only available for constant pressure units with control on one flow (Factory menu).
