9.5.1 Wired
Wired connection of the home automation system to the receiver takes place via a 0-3VDC direct current (see fig. 9-2 (D)).
3
A higher voltage than 3V will damage the receiver and is therefore not permitted.
2
In case of home automation systems with an output voltage of 0-10V, you should switch the voltage back to 0-3VDC. Use
a voltage distributor made of resistors. For example, 2200 ohms and 680 ohms. The voltage above 680 ohms resistance
can be used on the input of the 0-3VDC. Low ohmic resistors must be used.
By controlling the height of the voltage, the receiver will be able to calculate the position of the appliance. Graph 9.1
shows the relationship between the voltage, the height of the flame and the number of burners (1 or 2).
Proceed as follows when connecting the home automation system to the receiver:
1
Connect the 0-3VDC signal to the connector, to which a black and yellow wire are connected (see fig. 9-2 (D)).
1
Use the orange remote control to set the option for wired connection: go to position 8 in the first menu and select option
2 for an appliance with one burner and option 3 for an appliance with two burners. For this, read the manual for the
orange remote control.
3
The yellow wire is the + pole, the black wire is the - pole. Always connect ‘- to -‘ and ‘+ to +’ .
