To address the VVT Zone Controller

You must give the VVT Zone Controller an address that is unique on the network. You can address the VVT
Zone Controller before or after you wire it for power.
If the VVT Zone Controller has been wired for power, pull the screw terminal connector from the
1
controller's power 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.
