Important Wiring Considerations
Please read carefully and apply the following information when
wiring the Lead/Lag Controller:
1. To operate the Lead/Lag Controller, you must connect power
to the 24 VAC input terminal block.
Installation & Wiring
Figure 2: Lead/Lag Controller Wiring Diagram
2. Check all wiring leads at the terminal block for tightness.
Be sure that wire strands do not stick out and touch adjacent
terminals. Confi rm that all sensors required for your system are
mounted in the appropriate location and wired into the correct
terminals. See Figure 2 for wiring.
1.)24 VAC Must Be Connected So
That All Ground Wires Remain
Common.
3.)All Communication Wiring To Be 18
Ga. Minimum, 2 Conductor Twisted
Pair With Shield. Belden #82760 Or
Equivalent.
4.)It Is Recommended That The
Address Switch Is Set Before
Installation.
2.)All Wiring To Be In Accordance With
Local And National Electrical Codes
and Specifications.
