Addressing the VAV Zone II

You must give the VAV Zone II an address that is unique on the network. You can address the VAV Zone II before
or after you wire it for power.
If the VAV Zone II has been wired for power, pull the screw terminal connector from the controller's power
1
terminals labeled Gnd and 24 Vac. The controller reads the address each time you apply power to it.
Using the rotary switches, set the controller's address. Set the Tens (10's) switch to the tens digit of the
2
address, and set the Ones (1's) switch to the ones digit.
EXAMPLE If the controller's address is 25, point the arrow on the Tens (10's) switch to 2 and the arrow on
the Ones (1's) switch to 5.
