The Unit Vent Controller – 0-10V Output controls 24 Vac loads only. The maximum rating is 12 VA
for each DO. For higher VA requirements, 110 or 220 Vac requirements, separate transformers
used to power the load, or DC power requirements, use an interposing 220 V 4-relay module
(TEC Relay Module P/N 540-147).
