CAUTION:
The Room Pressurization Controller –
Electronic Output controls 24 Vac loads
only. The maximum rating is 12 VA for
each DO. Use an interposing 220V 4-relay
module (P/N 540-147) 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.
NOTE:
When wiring any actuator that uses a 0
to 10V control signal and ties AC neutral
to DC common, an additional wire
must
connect the actuator AC neutral to the
DC common of the PTEC/TEC AO
being used to control the actuator.
