NOTE
Bypass switching commands from safety functions or the au-
tomatic bypass have a higher priority!
To protect from freezing at low outside air temperatures (<
+1°C), the bypass flap can be automatically moved briefly on a
regular basis. To do this, the frost protection switching interval
is set in the range 5 ... 60 min.
The factory setting is 0 min.
9.7 Special functions for control
element
(with optional I/O board only)
The function of a key and the LED display for the control ele-
ment (Type 1) can be configured differently for a special func-
tion if required. The electrical terminal assignment remains un-
changed. The necessary adjustment of the input function
configuration for the key assignment is made in the service
menu under 40 - Inputs and for the output function for the LED
display in the service menu under 50 - Outputs.
Example 1:
Programming bypass switching to the key

For the assignment of the key in the service menu under
40 - Inputs / 42 Input IN_1, switch to the BYPASS function
with “Pos” signal (operating mode setting only
possible using key)

For the status display in the service menu under 50 Out-
puts / 51 Output OUT_0, switch to the BYPASS function
with "Low" signal (error signal now only on ventilation unit
display)

Set the manual bypass control to > 0 h in the user menu
under 20 - Settings / 225 Bypass manual.

Mode of action: Each press of the ? key switches over the
bypass. If the bypass is open, an orange LED is lit. The by-
pass closes automatically after the set max. opening time
at the latest.
Example 2:

 For the key assignment in the service menu under 40 In-
puts / 41 Input IN_0, switch to the TIMER_STAGE_3 func-
tion with "Pos" signal (the operating mode can now only be
