CONTROL PANEL MOUNTING
5
The control panel is wired straight from the VALLOX 90 SE electrical connection box. The control
panel can also be connected in series with a CO
2
sensor or another control panel.
(See External electrical connections on page 11).
Control panel addresses
If two or more control panels are connected to the system, the addresses of the control
panels need to be changed.
E.g. 3 control panels.
• Connect the first control panel to the unit and change its address to 3.
• Connect the second control panel to the unit and change its address to 2.
• Connect the third control panel and make sure that its address is 1.
If control panels have the same address, they go to bus fault state. In this case, remove one of the control
panels and change the address of the other panel. The above mentioned situation can arise in connection
with the later installation of an additional control panel.
