Hint:
This sound module plays the sound if no figure is connected to the synchronous input.
4.1 Connection of an external loudspeaker
The sound module is equipped with an output for an external loudspeaker with electrical values of 8 ohm impedance at
least and 1/2 watt power at least (can be purchased in an electronics specialized shop). In case you connect an external
loudspeaker the integral loudspeaker will be switched off.
1. Please pull the sound module’s short blue cable out of the socket right beside it.
2. Insulate the blue cable, to avoid any contact with other cables.
3. Mount the external loudspeaker at the intended place.
4. Install the two wires of the external loudspeaker to the sound module.
5. Connect the two wires to the two sockets according to fig. 3.
You can use plugs and sockets for the connection, e. g. Viessmann item 6875 (orange plug) and item 6884 (orange
socket).
4.2 Volume adjustment
The sound module is equipped with a volume control for the sound. The adjustment is valid as well for the integral loud-
speaker as for an external loudspeaker.
To adjust the volume, use a slotted screwdriver and proceed as follows (see fig. 4):
-
Increase volume:
Turn the poti to the right.
-
Reduce volume:
Turn the poti to the left.
5. Trouble-shooting
All Viessmann products are produced with high quality standards and are checked before delivery. Should a fault occur

Please check first the power supply and the wiring.
No sound from the module. No sound from the external loudspeaker.
- Turn the poti to the right.
- Please make sure that the small blue plug at the housing of the sound module is removed from the socket and is in-
sulated.
Connect the external loudspeaker as shown in fig. 3.
