NEXT OCCUPIED DAY — The Next Occupied Day point
displays the day of week when the next occupied period will
begin. This point is used with the Next Occupied Time so the
user will know when the next occupied period will occur. If the
fan coil is following a global schedule this point will remain at
default.

NEXT OCCUPIED TIME — The Next Occupied Time point
displays the time day when the next occupied period will
begin. This point is used with the Next Occupied Day so the
user will know when the next occupied period will occur. If the
fan coil is following a global schedule this point will remain at
default.
NOTE: If the current mode is occupied, this point makes refer-
ence to the next occupied period and, in most cases, it will not
be the same as the current occupied start time.

NEXT UNOCCUPIED DAY — The Next Unoccupied Day
point displays the day of week when the next unoccupied peri-
od will begin. This point is used with the Next Unoccupied
Time so the user will know when the next unoccupied period
will occur. If the fan coil is following a global schedule this
point will remain at default.

LAST UNOCCUPIED DAY — The Last Unoccupied Day
point displays the day of week when the fan coil last changed
from occupied to the Unoccupied mode. This point is used in
conjunction with the Last Unoccupied Time to know the last
time and day when the fan coil became unoccupied. If the fan
coil is following a global schedule this point will remain at
default.

point displays the time of day when the fan coil last changed
from occupied to the Unoccupied mode. This point is read in
conjunction with the Last Unoccupied Day to know the last
time and day when the fan coil became unoccupied. If the fan
coil is following a global schedule this point will remain at
default.

Fan Coil Maintenance Table —
The Fan Coil Main-
tenance Table is used to service the fan coil. See Fig. 43.
OCCUPIED — The Occupied point indicates if the Fan Coil
is operating in the occupied mode.
Occupied:
Display Range
No/Yes
Default Value
No

LINKAGE IN EFFECT — The Linkage in Effect point dis-
plays whether an air source linkage is in effect. This means the
fan coil controller is being controlled by a Linkage Thermostat.

Default Value
No

TIMED OVERRIDE IN EFFECT — The Timed Override In
Effect point shows if a timed override is currently in effect.

START BIAS TIME — The Start Bias Time, in minutes, is
calculated during the unoccupied period by the fan coil control-
ler as needed to bring the temperature up or down to the set
point under the optimum start routine. The start time bias for
heat and cool are configurable. This value will be reported to
the Linkage Thermostat if it is used. It will also be used by the
fan coil’s internal occupancy schedule to determine the start
of the Optimal Start period. It cannot be used with Global
Scheduling.

SET POINT OFFSET — The Set Point Offset point displays
the set point offset currently requested at the 33ZCT56SPT and
33ZCT57SPT room sensor with set point offset capability. the
set point offset value is calculated only during occupied peri-
ods.

T57 STATUS — The 33ZCT57SPT thermostat provides a
voltage input to the fan coil controller in order to select fan
speed operation. The 10 vdc power and ground are provided by
the fan coil controller and the potentiometer wiper provides the
voltage signal back to the zone controller. The following is a ta-
ble of values displayed by the T57 Status and acceptable volt-
age ranges for each fan speed position:
