E16 Home automation Setup
The DF-Series fireplace has a simple interface for connection to a home automation system. Simply
put this allows the fireplace to be woken up and started and then shut down. The “Close to wake” con-
nection shown is essentially taking one of the 3.3 volt DC pins on the fireplace micro controller and
pulling it down to ground. In order to isolate the fireplace from the automaton system a relay needs
to be used as shown. This allows you to use any nominal voltage to drive the relay while keeping the
fireplaces 3.3V supply isolated.
Note: you will need to match the relay coil voltage with the volt-
age from your automaton system.
The Home Automation connection can be found to the right of
the electronics tray (for access instructions see section E3). The
socket is shown to the right and can be identified by green wires.
E17 Home Automation Operation
Relay closed
The fireplace will start in a medium setting until it receives a signal from the remote control unit (up to
3 minutes). Once the remote has communicated with the fireplace it will turn on and begin operating
the fireplace thermostatically. The remote will use whatever temperature the user has previously set
and cannot be altered by the home automation system. The fireplace will continue to operate while the
relay is closed.
Note: If the fireplace cannot communicate with the remote controller within 10 minutes of the relay
contact closure then the fireplace will shut down and return to standby. The remote controller is
required to be operating within range of the fireplace for its safe operation.
Relay open
If the fireplace was operating with a closed relay then upon opening the relay contacts the fireplace will
shut down and return the remote controller to its standby mode when it next updates (up to 3 min-
utes). While the relay is open the fireplace will be in standby mode and available for manual operation
by the user.
