Additional installations and electrical components in the ventilation unit are not permitted!
Connection diagrams for further fan functions available on request!
Caution! Any installation work on the ventilation unit may only be carried out with the mains
voltage disconnected! The ventilation unit is insulated in accordance with protection class II, a
protective conductor connection is not required.
Make sure all connection lines are de-energized before connecting the ventilation unit to the
power supply! (Disconnection from power supply with at least 3 mm contact opening, e.g.
fuse)
Each circuit connected to the ventilation system must be fitted with residual current protection
(e.g. RCD switch)!
Electrical connections must be carried out by qualified staff only!
6.1 Automatic operation with humidity control according to DIP switch position of the
control board.
Comfort control: Humidity controlled operation
Basic control: Interval switching possible
6.2 With remote control (0 - 10 V)
The remote control input is divided into two ranges. In the range of 0-5 V the level is
set absolutely, i.e. with highest priority (corresponds to DIP 6,7 with switched L1 ). In the
range of 6-10 V only the base load is set (corresponds to DIP 1,2). In the range of
0-0.4 V the fan operates autonomously.
6.3 Depending on the control board, DIP switch position and module:
With run-on time (basic control): Deactivation of the run-on functions (L2), conti-
nuous operation basic ventilation or OFF according to DIP switches 1 and 2 swit-
chable to regulated ventilation (L1) according to DIP switches 6 and 7
With humidity control (comfort control): Humidity control can be deactivated (L2),
switchable to regulated ventilation (L1)
Note: No light coupling possible with VDE-compliant installation
((R) Bridge)
6.4 Depending on control board, DIP switch position and module:
Single-stage operation, switchable to regulated ventilation
Continuous operation basic ventilation and run-on time-controlled regulated ventila-
tion
Humidity control, switchable to regulated ventilation
Run-on time-controlled regulated ventilation
Note: Use a two-pole switch to switch the room lighting simultaneously with the
regulated ventilation!
6.5 Direct connection to TAC via F+ and F-.
