CAUTION:
The Room Pressurization Controller
– Pneumatic 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 220V 4-relay
module (TEC Relay Module P/N
540-147).
NOTE: Refer to the unit wiring diagrams or consult
with the local representative if terminations are
missing or are different.
