5.9 Operating with an external switch (option)
CAREFUL! The shutdown switch does not function in
combination with the home automation connection.
5.9.1 Connecting home automation system (option)
•
red = contact 0/10V
•
blue = GND
•
black = connecting wire (shut down switch)
Fig. 21: SDS-DOMO combi-cable connected to HDIMS
1. Connect the red wire of the SDS-DOMO combi-cable to the
output signal (D/C) of the home automation system.
2. Connect the blue wire to the GND terminal of the home
automation system.
3. Use heat-shrink cable to insulate the connections and avoid
short-circuits.
4. Connect the home automation cable to the automatic
burner relay.
5. Adjust the home automation system to the following
values:
•
1.5V Hybrid function.
•
3.0V Heat demand, the fire will ignite.
•
3.0 - 9.0V flame intensity is adjusted by modulation:
low or high.
•
9.5V ECO mode.
•
0 V Fire switched off.
The remote control and the home automation system cannot be
used at the same time. The remote control can only be used if
there is no current supplied to either of the two contacts.
In the event of an error message, the system should always be
reset using the remote control. For this reason, the remote
control must always be located near the receiver.

5.9.2 SDS-DOMO combi-cable for external switch
(option)
The shutdown switch ensures that the power is turned off while
the burner control (HDIMS) continues to be fed a constant power
supply (in a hotel or an exhibition space, for example). The shutoff
switch must be connected to the SDS-DOMO combi-cable.
When the switch is shut off the flamed will be extinguished, the
electronics of the appliance will remain active and the remote
control will display the notification 04F. The flame stays in a
blocked position so long as the switch is inactive. When the switch
is operated, it will open and the flame will be ignited. Connect the
two black wires of the SDS-DOMO combi-cable to the switch.
Use heat-shrink cable to avoid short-circuits. See: Wiring diagram
on page 86.
Example:
In the electrical diagram below, the SDS-DOMO combi-cable is
connected to a keycard to open a hotel room. In the example, the
gas fire is operated simultaneously.
1. Starting position > F04 error message.
2. The gas fire cannot be turned on.
3. When the keycard is inserted, the gas fire relay is turned on.
4. The relay opens the contact of the shutdown switch in the
gas fire.
5. The F04 error message disappears after approximately one
minute.
6. The gas fire is unblocked.
7. The gas fire can be switched on.
8. The gas fire operates.
9. If the keycard is removed, then the power to the relay of the
gas fire is turned off.
10. The relay closes the contact of the shutdown switch in the
gas fire.
11. The gas fire switches off automatically (stand-by).
12. After approximately one minute, the remote control returns
to the starting position.
If the keycard is reinserted within one minute:
13. The relay opens the contact of the shutdown switch.
14. The gas fire is unblocked and automatically switches on.
5.10 Connector for external devices (option)
It is possible that external devices can be connected to the gas fire
that switch oin or off at the same time as the fireplace is switched
on or off. External devices can be connected on the " open enable "
or " aux enable " burner control with a connector that can be
ordered from Kalfire.
