Sequence of
Operation
Timed Override Activation - ICS™
This function is operational whenever the
unit’s RTM module is used as the zone
temperature sensor source, which can be
set at the HI panel. When this function is
initiated by the push of the override
button on the zone sensor, the unit will
switch to the occupied mode. Unit
operation (occupied mode) during timed
override is terminated by a signal from
Tracer
®
.
Timed Override Activation - Non-ICS
This function is active whenever the unit’s
RTM module board is selected as the
zone temperature source, which can be
set at the human interface panel. When
this function is initiated by the push of the
override button on the zone sensor, the
unit will switch to the occupied mode.
Automatic cancellation of the timed
override mode occurs after three hours
of operation.
VAV Drive Max Output
This is a single-pole, double-throw relay
rated at a maximum voltage of 24 vac, 2
amps max. The relay contacts of this
relay switch when the unit goes from the
occupied mode to the unoccupied mode
by means of the unoccupied binary input,
night setback zone sensor, or Tracer
Summit
®
. The contacts will stay switched
during the unoccupied and morning
warmup mode. They will return to the
position shown on the unit wiring
diagram when the unit returns to the
occupied mode. The intent of this binary
output is to signal the VAV boxes or other
terminal devices to go to a full open
airflow position.
