For connecting external user interface: see Appendix A.
4.4 PIR sensor input
A PIR sensor can be connected, see Appendix A, to control the demand using presence detection. For the time
that at least the main burner is on, after a timeout of not noticing a person, the demand is set to 0. Depending on if
the system has a pilot flame available, the pilot flame always remains active.
Once the demand was set to 0, only a user action can turn on the burner again. To be able to turn the fireplace
back on, person present needs to be detected (someone needs to be in the room) otherwise a fault is triggered.
Note: If the system has an active pilot flame and this fault occurs during igniting, the pilot flame will be
turned off.
Besides connecting a wired PIR sensor to the DFGT it is also possible to bind a RF PIR
(1)
. The functionality is the
same as the wired PIR except that the timeout of not noticing a person is determined by the setting with tag 55
Person present timeout time and the time it takes for the RF PIR to not detect a person.
The person present control is independent of a current active control. That means that while a current control is
active, the person present control becomes active when:
it is configured as an input or an RF PIR is bound
the person present control is inactive
a person is detected first.
The timeout count in minutes is adjustable via the following setting.

4.5 0 – 10 volt input
The demand for the main and secondary burner can be controlled by supplying 0 to 10 volt to pin 3 (0-10V) and pin
10 (GND) of connector JP1.
