Local Temporary Override

OCCUPIED PERIOD

When in either the morning, day or evening program, the temperature setpoints

may be changed at the zone thermostats by simply pressing the

✞ or ✟ buttons.

The selected setpoints remain valid for the duration of the occupied period. When

the unit changes over to the unoccupied period, the override setpoints are discarded

and the thermostat reverts to the setpoints established by the SZP control module

for the night program.

UNOCCUPIED PERIOD

System: Unoccupied mode occurs when all zone thermostats are in night mode.

Local: Unoccupied mode occurs when a zone thermostat goes into night mode.

The minimum temporary override is one (1) hour and will remain in effect until the

one (1) hour period has elapsed. Moving into an unoccupied period (night mode)

during this minimum temporary override will not affect its status.

During the unoccupied period, zones 1-13 act as MUST SERVICE zones when the

zone thermostat

✞ or ✟ buttons (system override) are depressed. Zones 14-19 do not

act as MUST SERVICE zones at this time.

Keypad Lockout

With the keypad locked out (DIP switch #2 in the ON position) the MODE, FAN,

and

✞ and ✟ buttons are disabled; the lock symbol $ appears when these buttons are

pressed. The OUTDOOR and ZONE buttons still function.
