➠
Hold down the reset button on the receiver, until you hear two consecutive sound
signals (
see Appendix 4, Fig. 23
).
➠
After the second, longer signal, let go of the reset button.
➠
Press the ‘small flame’ button on the remote control for 20 seconds, until you hear
two short sound signals: this is the confirmation of a good communication.
7.3 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 Ap-
pendix 4, Fig. 19 ). 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 sup-
plied 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 ap-
pliance 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.
8. Final check
In order to check whether the appliance is working properly and safely, you must perform the following checks before
the appliance is used.
8.1 Gastightness
Caution
All connections must be gastight.
!Caution
The gas control block can be subjected to a maximum pressure of 50 mbar.
➠
Check the connections for gastightness.
8.2 Gas pressure / pre-pressure
The burner pressure is set at the factory; see type plate. It is not necessary to check the burner pressure.
The pre-pressure in house installations, however, should be checked, as they can vary.
➠
Check the pre-pressure; see Appendix 4, Fig. 22 for the measuring nipple on the gas control block;
➠
Contact the gas company if the pre-pressure is not correct.
8.3 Ignition pilot and main burner
For igniting the pilot and main burner, see the User Manual, chapter 4, Operation.
Caution
Always wait 5 minutes after the pilot flame has gone out, before you re-ignite the appliance.
