VCC-X Controller Outputs
The VCC-X Controller must be connected to 24 VAC as shown
in the wiring diagram below. Please see Table 1 for correct VA
requirements to use when sizing the transformer(s) used for powering
the Controller.
Also please note that when wiring the VCC-X Controller, its contacts
must be wired as wet contacts (connected to 24 VAC).
