INSTALLATION MANUAL
6.3Alternativeoperation
Appliances made with an electronic ignition and radio remote control can be connected to an alternative external
control system (e.g. Domotics). For this purpose, there are 4 connection points at the side of the receiver (see
Appendix 3, fig. 44). For connecting an external control unit, you will need a “Domotics connection cable for
GV60”. Consult DRU's service website.
The following contacts are possible:
• Ignition: connect both contacts 1 + 3, for one second (if there is a 2nd thermocouple, the appliance should
burn at full power for at least 20 sec. before the required position can be chosen).
• Flame high(er): briefly close contact 1 once per step, or 12 seconds for the highest position.
• Flame low(er) until switch-off (pilot flame remains on): briefly close contact 3 once per step, or 12 seconds for
the lowest position.
• Completely switching off the appliance (pilot flame included): close all three contacts 1 + 2 + 3, for one
second.
The appliance will always continue to respond to the radio remote control supplied with it. The external control
system is able to use one of the two modes of this remote control.

1. Manual mode
This mode of the remote control is passive and will not take any action unless it is operated. The external control
system is able to control the functions for high/low position, ignition and switching off.
!Tip If the external control system has an intelligent clock function and/or thermostat function, the remote control
supplied with the appliance should have the manual mode in order to prevent interruption of these functions.
2. Clock/thermostat mode
This mode of the remote control is active and will be responsible for the clock function and thermostat function.
The external control system is able to control the functions for high/low position, ignition and switching off.
!Tip • If the appliance is switched off (the pilot flame included) manually or by one of the safeguards, ignition of the
appliance will be blocked for a period of 3 minutes for reasons of safety.
• If it is no longer possible to operate the appliance with the external control system, you must switch it off and
then switch it on again with the supplied remote control.
7.Finalinspection
In order to check whether the appliance is working properly and safely, you must perform the following
inspections before the appliance is used.
7.1Gastightness
!Caution All connections must be gastight. Check the connections for gastightness.
The gas control can be subjected to a maximum pressure of 50 mbar.
7.2Gaspressure/line-pressure
The burner pressure is set at the factory; see data plate.
!Caution The line-pressure in house installations must be checked, because it can be wrong.
Ø Check the line-pressure; see Appendix 3, fig. 41 for the measuring nipple on the gas control.
Ø Contact the gas company if the line-pressure is not correct.
