DIP Switch

The Control Point panel is equipped with a 3-position DIP switch. Each of three sections has a separate function:

• the first switch allows for restoring default settings;

• the second switch allows for selecting a communication protocol;

• and the third switch allows for the RS485 network termination.

Restoring Default Settings

The first switch provides a possibility to restore default settings in the panel. In order to do so, follow the steps below:

• Turn off the power supply;

• set the first switch to on;

• turn on the power supply;

• wait until LCD backlight starts blinking;

• set the first switch to off.

Selecting Communication Protocol

The second switch selects between the available communication protocols, Modbus RTU/ASCII or BACnet MS/TP:

• Off: Modbus RTU/ASCII (default for Control Point series),

• On: BACnet MS/TP (default for Control Point VAV series).

RS485 Network Termination

The third switch adds or disconnects a termination resistor to the RS485 network:

• Off: termination resistor disconnected (default);

• On: termination resistor added (120 Ω).
