or on occupied startup, control is delayed for this
amount of time.

and programming screens begin with #1. Access may
be locked out with dipswitches, or an access code may
be required.
Setting Clock & Schedule
The SZ1064 clock and schedule may be set through the
keypad and display, or with a PC. For more information
on programming through the PC, consult your TCS soft-
ware manual.
SETTING CLOCK & SCHEDULE
THROUGH THE KEYPAD
To access the clock and schedule screens in step #2
select yes. To make changes, use the warmer and
cooler keys. For screens that have more than one field
to set, use the override key to move to the next field. An
access code may be required.
Operation
UNOCCUPIED SETBACK
The SZ1063 and SZ1064 operates, in either an occu-
pied or unoccupied mode. During the occupied mode,
the occupied heating and cooling setpoints will be main-
tained, and the fan will operate according to its occupied
setting. During the unoccupied mode, the unoccupied
heating and cooling setpoints will be maintained, and
the fan will operate according to its unoccupied setting.
The occupied LED will be lit when the unit is operating
in the occupied mode.
The occupied schedule may be set utilizing the internal
time clock (SZ1064 only) or DI3 may be used with an
external time clock, whereas when DI3 is closed, the
unit is in the occupied mode. The Smart Recovery func-
tion is disabled when DI3 is used for external time clock.
OVERRIDE
A timed override is available using the button on the
face of the thermostat or through momentary contacts
wired into the OVR terminal. The amount of time the
unit will be overridden is set from 0 to 255 minutes in
the programming screen. This override behaves differ-
ently depending on the mode the thermostat is operating
in (occupied or unoccupied) and the options that have
been enabled within the software.
In standard mode, the override only activates in unoc-
cupied mode and takes the thermostat into occupied
mode. If "Override for Occupied Period" is enabled using
the software, the override also activates in occupied
mode and takes the thermostat into unoccupied mode.
In either case, you are able to view the time remain-
ing in the override period both within the software and
by using the service button to scroll through the status
screens. If the occupant desires to return the thermostat
to unoccupied or occupied operation (depending on how
the override was used) before the override time remain-
ing elapses, they may press the override button again.
