Please contact your installer to find air pressure for your system. It may nec-
essary to perform several tests and calibrations to find pressure, increased by
the cooker hood, at which the differential pressure switch gets activated.
Note:
The exhaust air pressure and air pressure increase caused by the cooker hood is different for each
ventilation system.
Set the switch activation pressure value using the knob under the lid. The setpoint value is visible through
the lid.
Configuration
1. Go to Service menu
2. Enter password (default 1111)
3. Go to Input menu. Select UNIVERSAL tab.

5.5.4 Multiple control panels
Multiple control panels (up to 10) can be connected to one unit with the help of diverting plugs. A single diverting plug
allows to connect two control panels. A diverting plug can be connected to another diverting plug to further increase
the number of control panels that can be connected simultaneously.
Note:
• If the 24 V power supply on the connection board (CB) is used for other equipment, the number of control
panels that can be powered from the unit will decrease.
• A single active control panel draws 50 mA. The connection board supplies up to 250 mA. If no other
accessories use 24 V power supply from the unit, up to 5 control panels can be connected without a need
of external power supply. In order to connect more than 5 control panels, an external power supply is
required.
Control panel is available in black or white colour.
