Ventilation in comfort
mode deadband
In the comfort mode deadband, the fan may be on
continuously, be off, or turn on periodically for a set number of
seconds:
0 = ventilation off
1 = permanent ventilation, any season
2 = permanent ventilation in summer
3 = ventilation periodically restarted
0:1:2:3
Read/Write
P41
Ventilation in standby
mode deadband
In the standby mode deadband, the fan may be on
continuously, be off, or turn on periodically for a set number of
seconds:
0 = ventilation off
1 = permanent ventilation, any season
2 = permanent ventilation in summer
3 = ventilation periodically restarted
0:1:2:3
Read/Write
P42
Ventilation in economy
mode deadband
In the economy mode deadband, the fan may be on
continuously, be off, or turn on periodically for a set number of
seconds:
0 = ventilation off
1 = permanent ventilation, any season
2 = permanent ventilation in summer
3 = ventilation periodically restarted
0:1:2:3
Do not change/
Manufacturer only
P43
Ventilation in frost
protection mode
deadband
In the frost protection mode deadband, the fan may be on
continuously, be off, or turn on periodically for a set number of
seconds:
0 = ventilation off
1 = permanent ventilation, any season
2 = permanent ventilation in summer
3 = ventilation periodically restarted

P44
Time between two
periodic restarts
The time set in this parameter is that during which the fan is off
if it must run periodically in the deadband zone
10…120 (resolution of 10)
Do not change/
Manufacturer only
P45
Restart time
Restart time if the periodic restart function is enabled on the
above parameters
30…180 (resolution of 30 s)
Do not change/
Manufacturer only
P46
Time delay between fan
speeds (in Auto mode)
The fan does not shift directly to speed 3 without first
remaining at speed 1 or 2 for a minimum period (in minutes).
This also prevents oscillation of the fan speed during hysteresis
0…10
Do not change/
Manufacturer only
P47
Operating mode selected
by the sleep button on the
user terminal (former P79)
The time set in this parameter is that during which the fan is off
if it must run periodically in the deadband zone
1 = Comfort --> Frost protection
2 = Comfort --> Economy
3 = Comfort --> Standby

P48
Comfort override delay
Override to remain in comfort mode after comfort mode
activation from the user terminal. May be set to remain on at all
times, to turn on for a specific period, or be disabled.
0 = Override prohibited
0.5...24 = Override time in h
24.5 = Infinite override time
0.0…24.5 (increments of 0.5 h)

Do not change/
Manufacturer only/or ensure
wiring is in place for the
selected function
P50
Action direction of
auxiliary contact on input
D2
The auxiliary contact on input DI2 may be normally closed or
normally open:
0 = Normally open
1 = Normally closed

wiring is in place for the
selected function
P51
Input D1 function
Operating mode with window switch:
0 = Inactive
1 = Window switch (Comfort --> Frost protection)
2 = Presence contact (Comfort --> Eco)
3 = Presence contact (Comfort --> Standby)
4 = Condensate drain pump
5 = Fan unit motor alarm
6 = General alarm
7 = CO2 sensor
0…7
Do not change/
Manufacturer only/or ensure
wiring is in place for the
selected function
P52
Input D2 function
This parameter allows the input to have several functions:
0 = Inactive
1 = Window switch (Comfort --> Frost protection)
2 = Presence contact (Comfort --> Eco)
3 = Presence contact (Comfort --> Standby)
4 = Condensate drain pump
5 = Fan unit motor alarm
6 = General alarm
7 = CO2 sensor
8 = Frost protection for "Fresh air"
9 = Condensation-free AC function
0…9
