COOL MODE HYSTERESIS- This decision is used to
configure the hysteresis that will be used to determine when the
cooling mode will end. The cooling mode ends when the
avelage cooling demand drops below the minimum average
demand minus the hysteresis: (average cooling demand < Cool
Start Avg. Demand -- Cool Mode Hysteresis)
Cool Mode
Hysteresis: Units delta F (C)
Range 0.5 to 5.0
Default Value 0.7
HEAT START AVERAGE DEMAND -- This decision is
used to configure the minimum average heating demand that
must be met before the system will st_ut in heating mode if no
mode is currently active.
NOTE: If there is also an average cooling demand, and it is
also greater than its configured minimum average cooling
demand (Cool Stml Avg. Demand), then the mode with the
greater demand will be selected. If both heating and cooling
average demand are exactly the same then the mode with the
greatest individual zone demand will determine the st_uting
system mode.
Heat St_u-t
Average Demand: Units delta F ((2_)
Range 0.5 to 5.0
Default Value 0.7
HEATMODE HYSTERESIS-- This decision is used to
configure the hysteresis that will be used to determine when the
heating mode will end. The heating mode ends when the aver-
age heating demand gets below the minimum average demand
minus the hysteresis: (average heating demand < Heat SUut
Avg. Demand - Heat Mode Hysteresis)
Heat Mode
Hysteresis: Units delta F ((2_)
Range 0.5 to 5.0
Default Value 0.7
SYSTEM MODE RESELECT-- This decision is used to
configure the minimum time that must elapse before a mode
change can take effect.
System Mode
Reselect: Units minutes
Range 0 to 255
Default Value 30
COOL TIME GUARD TIMER -- This decision is used to
configure the minimum time that the cooling mode must be ac-
tive before a mode change can take effect. The Cool Time
Guard Timer becomes active whenever the cooling mode goes
into effect.
Cool Time
Guard Timer: Units minutes
Range 0 to 255
Default Value 0
HEAT TIME GUARD TIMER -- This decision is used to
configure the minimum time that the heating mode must be
active before a mode change can take effect. The Heat Time
Guard Timer becomes active whenever the heating mode goes
into effect.
Heat Time
Guard Timer: Units minutes
Range 0 to 255
Default Value 0
CONT. FAN WHEN OCC -- This decision is used to config-
ure the air source fan to go On whenever the zone is in an occu-
pied mode. If this decision is set to No, the fan will cycle on
and off during occupied modes in order to maintain set point.
Cont. Fan
When Occ: Range No/Yes
Default Value Yes
HEAT MODE LOCKOUT SET POINT -- This decision is
used to lock out the heating mode by comparing this value to
outdoor air temperature. If the outdoor air temperature reading
is v_flidand greater than this value then the heating mode will
be locked out. If outdoor air temperature drops 3 degrees below
the Heat Mode Lockout Set Point, the lockout is cancelled.
This 3-degree hysteresis is fixed.

140
COOL MODE LOCKOUT SET POINT -- This decision is
used to lock out the cooling mode by comparing this v_flue to
outdoor air temperature. If the outdoor air temperature reading
is v_flid and less than this value then the cooling mode will be
locked out. If outdoor air temperature raises 3 degrees above
the Cool Mode Lockout Set Point, the lockout is cancelled.
This 3-degree hysteresis is fixed.
Cool Mode Lockout
Set Point: Units F (C)
Range -40.0 to 140.0
(-40 = disable)
Default Value M-0
Time Schedule Configuration Table
-- The Time
Schedule Configuration Table (OCCDEFCS) contains
decisions used to configure the zone controller's occupancy
schedule. For flexibility of scheduling, the occupancy configu-
ration is broken into eight separate periods. See Table 11.
MANUAL OVERRIDE HOURS -- The Manu_fl Override
Hours decision is used to command a timed override by enter-
ing the number of hours the override will be in effect.
If the occupancy schedule is occupied when this number is
downloaded, the current occupancy period will be extended by
the number of hours downloaded.
