Device Bus Number; Device Access Security Level; Communications; Information Broadcast - Carrier 33CS Installation, Service, And Troubleshooting Instructions

Device Bus Number —
connected to a single primary bus. On the primary bus, each
secondary bus has an address. When the TEMP system prima-
ry thermostat resides on a secondary bus, the bus address must
be entered into the Device Bus Number configuration. The de-
fault is 0. Acceptable values range from 0 to 239. The Device
Bus Number is set in category 8, option 3. The primary net-
work device bus number is always 0.
Secondary network buses can be added by using a network
bridge module. This secondary bus has a bus number equal to
the device address of the bridge module. Any thermostats on
this secondary bus must have their device bus number set equal
to the device address of the bridge module.
Device Access Security Level —
security level is used to limit access to the TEMP system ther-
mostat 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 security 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 programming
of occupied heating and cooling set points only. Access securi-
ty level 4 allows no programming.
Do not leave device access security level option at 1
after configuration is complete. Untrained or unauthorized
users may change set points or other important information.
If the access security level is changed from 1, the access se-
curity level cannot be changed back in the normal method be-
cause programming is not allowed. To reconfigure the access
security level of the TEMP system thermostat, activate the in-
formation display (simultaneously press both heating or both
cooling buttons). When the information display shows the ac-
cess security level (display number 3), press any button to
freeze the display. Then press both upper or both lower set
point buttons to enter the programming mode. Reconfigure cat-
egory 8, option 2 to the desired access security level.

COMMUNICATIONS

Information Broadcast —
stat broadcasts global information on the network. Global in-
formation 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 network
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 —
Check is activated, the TEMP system thermostat verifies that it
can communicate with each device addressed below 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 thermostat has

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

*If an ''E'' is shown in front of the device type designation, the device

The 3-digit number in the upper left-hand corner indicates
the device address currently being scanned. The device 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 system
thermostat occupancy schedule of the zone. See the Unoccu-
pied 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 —
lish the range of acceptable temperatures for the zone during a
given time period. The heating and cooling temperatures are
maintained in the zone controlled by the TEMP system ther-
mostat during the occupied mode. The range of allowable tem-
peratures is 50 to 99 F for heating and cooling (dependent 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 system 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 sys-
tem thermostat screen.
The TEMP system thermostat will continuously display
the occupied set points unless it is in unoccupied mode or dis-
play freeze has been activated or Rotating Display has been
enabled.
