CAUTION:
The controller’s DOs control 24 Vac loads only. The maximum rating is 12 VA for each DO.
Use an interposing 220V 4-relay module for any of the following:
• VA requirements higher than maximum
• 110 or 220 Vac
• DC power
• Separate transformers used to power the load.
NOTE: Refer to the unit wiring diagrams or consult with the local representative if terminations are
missing or are different.
