Note:
24 VAC dampers can be powered and
controlled only by using a relay mounting kit
with a transformer (article number: 153548).
This installation procedure describes how to connect
dampers powered by 230 V~ with a relay mounting kit
without transformer (article number: 153549).
Installation and connection
1. Install dampers (U/V).
2. Connect control signal wires (24V, DO) coming out from
the relay box (RL) to any free digital output on the con-
nection board (CB).
3. Connect power supply wires (N) from dampers to the
terminal block. Connect control signal wires (Y, line)
from dampers to relay socket terminals (11, 21). See
illustration.
When damper with a non-spring return actuator is
used, an addition power line (L) has to be connected to
the terminal block since such damper requires constant
power supply.
4. Connect power supply wires (L, N) coming out from the
relay box to 230 V~ power source.
Configuration
1. Go to Service menu
2. Enter password (default 1111)
3. Configure control signal to the relay. Go to Output menu. Select DIGITAL tab. Select the digital output to which the
relay is connected. Example if it is connected to DO3 on the connection board, then select DIGITAL OUTPUT 3 and
select signal type as Outdoor-/Exhaust Air Damper from the output type list.

SAVE /B series have a dedicated 5th duct for air extraction through a cooker hood. This duct bypasses the heat ex-
changer and air from the kitchen gets removed directly to the outside.
