Device Bus Number —
ses connected to a single primary bus. On the primary bus,
each secondary bus has an address. When the TEMP system
primary thermostat resides on a secondary bus, the bus ad-
dress must be entered into the Device Bus Number configu-
ration. The default is 0. Acceptable values range from 0 to
239. The Device Bus Number is set in category 8, option 3.
The primary network device bus number is always 0.
Secondary network buses can be added by using a net-
work bridge module. This secondary bus has a bus number
equal to the device address of the bridge module. Any ther-
mostats on this secondary bus must have their device bus
number set equal to the device address of the bridge module.
Device Access Security Level —
cess security level is used to limit access to the TEMP sys-
tem thermostat functions by unauthorized personnel. The device
access security level is configured in category 8, option 2.
The factory setting is 1. The range of acceptable access se-
curity levels is 1 to 4.
Access security level 1 allows full programming of the
TEMP system thermostat. Access security level 2 allows pro-
gramming of occupied set points, occupancy schedules, and
holiday schedules. Access security level 3 allows program-
ming of occupied heating and cooling set points only. Ac-
cess security level 4 allows no programming.
Do not leave device access security level option at 1
after configuration is complete. Untrained or unautho-
rized users may change set points or other important
information.
If the access security level is changed from 1, the access
security level cannot be changed back in the normal method
because programming is not allowed. To reconfigure the ac-
cess security level of the TEMP system thermostat, activate
the information display (simultaneously press both heating
or both cooling buttons). When the information display shows
the access security level (display number 3), press any but-
ton to freeze the display. Then press both upper or both lower
set point buttons to enter the programming mode. Recon-
figure category 8, option 2 to the desired access security level.

COMMUNICATIONS

Information Broadcast —
mostat broadcasts global information on the network. Glo-
bal information is available to each device on the network.
If the TEMP system thermostat is equipped with an elec-
tronic timeclock, the time, day of the week, and year can be
broadcast to the network. Network time is broadcast 2 times
per day (1 AM and 1 PM).
When the Outside-Air Temperature Sensor option (5.8) is
set to ON, outside-air temperature is broadcast to the net-
work every 15 minutes.
NOTE: If the TEMP system thermostat has a timeclock, and
is set up as the network time broadcaster, one of the other
TEMP system thermostats must be a time requester. This will
request time once every minute. This will ensure that the
other devices on the network will receive time once a minute.
Communication Check —
tion Check is activated, the TEMP system thermostat veri-
fies that it can communicate with each device addressed be-
low its own address. To activate a Communication Check,
set the category to 7 and the option to 2. Press a left set point
button to toggle the option to ON. When the TEMP system

When the Communica-
thermostat has completed the system scan, the Communi-
cation Check is automatically deactivated.
During a Communication Check, the TEMP system ther-
mostat scans consecutive device addresses starting with the
device address one less than the TEMP system thermostat
address. The TEMP system thermostat will continue to scan
until address 1 is reached.
The following information is displayed during a Commu-
nication Check:
• the device address being scanned
• device type
• if the device has any error
Refer to Table 2 for the Communication Check system
designations.

The 3-digit number in the upper left-hand corner indi-
cates the device address currently being scanned. The de-
vice type and error status designations are located in the lower
right-hand corner of the display.

OCCUPIED MODE OPERATION

Occupied mode is the time period when the TEMP system
thermostat maintains the occupied set point temperatures. Oc-
cupied time periods are configured to define the TEMP sys-
tem thermostat occupancy schedule of the zone. See the Un-
occupied Mode Operation section on page 11 for more
information on selection of time schedules.
During the occupied mode, the occupied set points:
• can be fully adjusted throughout the occupied set point range
• can be limited to maximum heating and minimum cooling
values within the occupied set point range
Occupied Set Points —
tablish the range of acceptable temperatures for the zone dur-
ing a given time period. The heating and cooling tempera-
tures are maintained in the zone controlled by the TEMP system
thermostat during the occupied mode. The range of allow-
able temperatures is 50 to 99 F for heating and cooling (de-
pendent on the occupied set point limits).
The left set point buttons control the cooling set point.
Press the top set point button to raise the set point. Press the
bottom set point button to lower the set point. The cooling
set point is displayed in the top left corner of the TEMP sys-
tem thermostat screen.
The right set point buttons control the heating set point.
Press the top set point button to raise the set point. Press the
bottom set point button to lower the set point. The heating
set point is displayed in the bottom right corner of the TEMP
system thermostat screen.
The TEMP system thermostat will continuously display
the occupied set points unless it is in unoccupied mode or
display freeze has been activated or Rotating Display has
been enabled.
