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 software manual.

Operation
UnoCCUPied SetBACk
The SZ1063 and SZ1064 operates, in either an occupied or unoc-
cupied mode. During the occupied mode, the occupied heating and
cooling setpoints will be maintained, and the fan will operate accord-
ing to its occupied setting. During the unoccupied mode, the unoc-
cupied 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 function is disabled when DI3 is used for external
time clock.
oveRRide
A timed override is available using the button on the face of the ther-
mostat 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 different-
ly depending on the mode the thermostat is operating in (occupied or
unoccupied) and the options that have been enabled within the soft-
ware. In standard mode, the override only activates in unoccupied
mode and takes the thermostat into occupied mode. If "Override for
Occupied Period" is enabled, the override also activates in occupied
mode and takes the thermostat into unoccupied mode. In either
case, you are able to view the time remaining 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 ther-
mostat to unoccupied or occupied operation (depending on how the
override was used) before the time interval is up, they may press the
override again. If "Continuous Occupied Override" or "Continuous
Unoccupied Override" is enabled, then pressing the override once
and then pressing and holding it for 5 seconds puts the thermostat
into a "hold” mode (the override LED on the thermostat will flash
quickly). In this mode, the override setpoints are used until the next
occupied period is reached, or until the thermostat is manually taken
out of the "Continuous Override" mode by pressing the override
again.
Continuous override is available through the DI3 contact or the
software. If DI3 is set to external override, the unit will be in the
occupied mode whenever the DI3 contact is closed. When using this
option, the timed override may still be activated.
