Use WattMaster 2
Conductor Twisted Pair
With Shield Cable Or
Belden 82760 Or
Equivalent To Connect
Between Each VAV/Zone
Controller Actuator
Package And From The
Unit Controller, MiniLink
PD Or CommLink To The
First VAV/Zone Controller
Actuator Package As
Required By Your
Application.
24VAC Transformer (By Others)
See Zone Controller Transformer
Sizing Information For Calculating
VA Requirements.
WARNING:
If Multiple Controllers Are Wired To A
Single Transformer As Shown, Polarity Must Be
Observed On All 24 VAC Wiring Or Damage To The
Controllers Will Result.
CAUTION:
Size Power
Wiring Per Wire Sizing
Information In This Manual.
Be Sure Wiring Is Sized For
Minimum Voltage Drop For
Your Length Of Wiring Run.
NOTE:
A Single Transformer Supplying Each VAV/Zone Controller
Individually Can Be Used Or A Transformer Supplying Several VAV/Zone
Controllers Can Be Used. Each Controller Requires 6 VA Minimum Power.
Do Not Exceed 16 Controllers Attached To One Transformer (96 VA). Also
See Warning Note Regarding Polarity.
