SPT SENSOR
TRIM -- Use this decision to trim the System
Pilot's
space temperature
sensor
if it needs calibration.
For
example, if the temperature
displayed is two degrees above the
value measmed
with calibrated test equipment,
input a value of
-2.0.
SPT Sensor Trim: Allowable
Entries -9.9 to 9.9 delta F
Default Value
0.0 delta F
SHOW NAME ON DEFAULT
-- Use this decision to specify
whether to display the 8-chfu'acter controller nmne on the top
line of the default screen.
NOTE: ff the System Pilot is on a Zone Controller's
local bus,
and if the zone controller's
addiess
has not been
set, the
System Pilot will show the Controller
ID screen as the default
screen. The 8-character
controller
name will not be displayed
on the top line of this screen.

DEVICE
(Carrier
Network
Mode)
-- The de-
fault device is the device to which the System Pilot will attach
when it is powered up. It is fdso the device to which the System
Pilot will attach if no user input is leceived for an horn:
If the System Pilot is on a local bus, the VVT® zone control-
ler will automatically
be the default device. If the System Pilot is
on the Carrier communicating
network, the user may specify the
default device's Bus Number and Element Numbel:
Default Device Bus Number
--
Use this decision to specify
the bus number
of the System
Pilot's default
device, if the
System Pilot is on the Cfurier communicating
network.
Default Device
Bus Number:
Allowable
Entries 0 to 239
Default Value
0
Default Device Element
Number
--
Use
this
decision
to
specify
the element
number
of the System
Pilot's
default
device, if the System
Pilot is on the Cfurier communicating
network.
NOTE:
If Element
Number
is 0, the System
Pilot is on the
Carrier network
bus, find Remote Attach is Enabled,
then the
remote
device
will be the default
device.
Otherwise,
the
System Pilot will be the default device.

WNITE SPT TO DEFAULT
-- Use this decision
to enable
or disable the System
Pilot's space temperature
update
func-
tion. If flris decision is set to Yes, file System
Pilot will send
its space temperature
to the default device once per minute or
whenever
the value
of the space
temperature
changes
by
0.3 ° E The System
Pilot will perform this function regardless
of the device to which the System Pilot is attached.
If Write SPT to Default
is Yes and the user disables
the
feature (sets it to No) or changes the default device, the System
Pilot will auto the SPT vmiable in the default device, allowing
it to return to its own value.
When the Communication
Mode decision is changed from
CCN to LOCAL or when the VVT zone controller's
controller
addiess is set in the Controller ID scleen, the System Pilot will
set Write SPT to Default to Yes.
If Write SPT to Default is Yes and the space temperature
sensor in the System Pilot fails, the System Pilot will auto the
space temperature
vfuiable in the default device and issue an
alarm message.
The System
Pilot will issue a return to normal
and resume writing SPT to the default device when the sensor
returns to norlllaL
Write SPT
To Default:
Allowable
Entries No /Yes
Default Value
No
ZONE
SET POINT
LIMITS
Cool Setpt Low Limit -- Use this decision to specify the low-
est value that can be sent to the cool set point in an attached
Zone Controllel:
If the value being sent is below this limit, the
System Pilot will clamp the value to this limit before sending it.
This limit will not affect the set point display. The System
Pilot will read the set point from
the Zone
Controller
find
display it as read, even if outside the high and low limits.
If clamping the set point results in a value that is outside the
configuration
limits read from file Zone Controller.
the System
Pilot will display an error indication
("LIMIT')
find will not
write the set point to the Zone Controllel:
