WARNING!!
Observe Polarity! All boards must be wired with GND-to-GND and 24VAC-to-24VAC. Failure
to observe polarity will result in damage to one or more of the boards. Expansion Modules
must be wired in such a way that the expansion modules and the controller are always
powered together. Loss of power to the expansion module will cause the controller to
become inoperative until power is restored to the expansion module.

Feedback
The VCC-X EM1 Expansion Module (OE336-23-VCCXEM1)
connects to the VCC-X Controller with an EBC E-BUS cable and
adds an additional 5 Analog Inputs, 5 Analog Outputs, 3 Binary
Inputs, and 5 Confi gurable Relay Outputs.
The VCC-X EM1 Expansion Module can be used in conjunction with
the E-BUS 12-Relay Expansion Module. The expansion modules
can be used individually or together to provide the required inputs
and outputs for your specifi c applications.
Title 24 Economizer Feedback
If the controller has been confi gured for Title 24 Economizer
operation, the Economizer Actuator Feedback signal will be wired
to the VCC-X EM1’s T3 input.
See Figure 25 below for wiring.
