List of Modbus Registers

Warning!

Please note that the following table contains registers for all series of the Control Point panels.

The Control Point VAV series by default has no fan control and registers referring to fan control are inapplicable. If the fan control is activated on the Control Point VAV series panel, the registers become applicable too.
