There are two Hex switches on the controller: S1 and S2, as
shown in Figure 14.
Figure 14
CPO-VAV2A Hex Switches Layout
Set S1 to the lower nibble of the address and S2 to the higher
nibble of the address.
Example: If you want to set 2 as the MAC address, S1 should
be set to 2 and S2 should be set to 0.
Similarly if you want to set 17 as the MAC address, S1 should
be set to 1 and S2 should be set to 1.
The following table illustrates the S1 and S2 switch settings
for the corresponding MAC addresses.
Analog Input
Analog inputs can be used, for example, to connect the wall
module, or temperature sensor to the controller.
Technical specification
•
4 analog inputs
•
AI 1, AI 2, AI 3, and AI 4 are universal, and can be used as

Attention
Make sure that each CPO-VAV2A controller on the
MS/TP bus has a unique MAC address. Valid
address for CPO-VAV2A is from 1 to 30. 0 is
reserved for the plant controller while CPO-Studio
uses addresses 32 and 35.
It also shall be ensured that CPO-VAV2A, CP-
VAV/SPC and CP-DIO on the same MS/TP bus
MUST NOT have the same MAC Address.
