SCHEDULE OVERRIDES

The 369 has a number of setback overrides that are selected through the schedule (Schd) menu. A system override and a zone override
are available. Any time an override is in effect, the

Ovr segment is displayed in the appropriate LCD.

System Override (OVERRIDE)

The system overrides affect every zone and are selected in the schedule (Schd) menu
of the control, remote display module (RDM), or display RTU. These setback overrides
have priority over any external setback signal.

Zone Override (ZONE OVR)

Zone overrides are only available for zones using display RTUs. The zone overrides
only affect the respective zone, and are selected in the schedule (Schd) menu of the
RTU or remote display module (RDM).

Temporary (TMPY)

If a temporary occupied or temporary unoccupied override is selected, the 369 operates the zone(s) in the selected override mode
for 3 hours from the time the selection is made. Once completed, the control reverts to the currently scheduled operation.

Permanent (PERM)

If a permanent occupied or permanent unoccupied override is selected, the 369 operates the zone(s) in the selected override mode
until a new override is selected.

Away (AWAY)

If the AWAY override is selected, the 369 reduces all the heating
setpoints to a maximum of 62

°F (17°C), and increases the cooling

setpoint to at least 82

°F (28°C). Also, slab minimum settings and all

existing schedules are ignored.

External UnOccupied Override

An external signal can place the 369 into unoccupied mode. Any time
the

UnO Sw (1) and the Com (4) terminals are shorted together, the

control overrides the occupied mode and operates in the unoccupied
mode. The

UnOcc Ovr segment is displayed in the appropriate LCD.

The control remains in the unoccupied mode as long as the signal is
present or until a system override is selected.
