Electronic Timeclock — The monitor thermostat may
be equipped with an electronic timeclock. The timeclock is
used for operation of the monitor thermostat unoccupied/
occupied time periods. The timeclock is also used for broad-
cast to other devices on the network.
To set the clock, remove the cover of the thermostat. Two
buttons, located under the timeclock, are provided to set the
clock, labeled select and adjust. See Fig. 16. Press the select
button. The hour setting on the clock will flash. Press the
adjust button until the correct hour is shown (including AM
and PM). Press the select button. The minute setting will
flash. Press the adjust button until the correct minutes are
shown. Press the select button again and the day of the week
will flash. Press the adjust button until the correct day is shown
(M = Monday,T=Tuesday,W=Wednesday, Th = Thurs-
day, F = Friday, Sa = Saturday, Su = Sunday). Press the se-
lect button again and the number of the month will flash.
Press the adjust button until the correct month is shown. Press
select again and the day of the month number will flash. Press
the adjust button until the correct number for the day of the
month is shown. Press the select button again and the year
will flash. Press the adjust button until the correct year is
shown. Press the select button to return to normal timeclock
operation. The timeclock is now set.
NOTE: If the monitor thermostat receives time from a net-
work device, the monitor thermostat time will revert back to
network time after the transmission.
Alternate Information Display — Allows the moni-
tor thermostat to display additional information. Simulta-
neously press the cooling or heating set point buttons, and
the monitor thermostat will display a sequence of informa-
tion. The information displayed is determined by the con-
figuration setting of Alternate Information. The display can
be frozen by pushing any set point button during the display
sequence. To begin the sequence again, press any set point
button and the display will continue.
The Alternate Information option can be set to ON or OFF.
To configure, set category to 7 and option to 3. Use the left
set point buttons to toggle the option ON or OFF.
When Alternate Information is ON and the System Status
mode is activated, the monitor thermostat will display the
following information (if available) in this order:
• (1) zone temperature
• (2) time, day of week, AM/PM
• (3) security level
• (4) duct temperature
• (5) zone damper position
• (6) outside-air temperature
• (7) outside air relative humidity
• (8) indoor air relative humidity
• (9) DX coil temperature
• (10) filter status (digital input)
• (11) fan status (digital input)
• (12) IAQ status (digital input)
• (13) number of heating callers
• (14) number of cooling callers
• (15) reference zone address
The information is shown on the top half of the display
screen. The identifying number of the sequence (1-15) is shown
in the bottom right corner to distinguish what is being dis-
played. The numbering is not shown when the Alternate In-
formation option is turned OFF.
When Alternate Information is OFF and the Information
Display mode is activated, the monitor thermostat will dis-
play the following information (if available) in this order:
• zone temperature
• time of day
• security level
Display Freeze — After Alternate Information Dis-
play is activated, press any set point button to continuously
freeze the display with the information shown when the set
point button was pressed. Press a set point button to resume
the Information Display sequence.
NOTE: Normal operation of the monitor thermostat is not
affected by the Display Freeze or Alternate Information Dis-
play operations.
START-UP
The start-up category for configuration contains impor-
tant communication, security, and operation information which
the monitor thermostat will need to operate correctly.
NOTE: The start-up category will be displayed when enter-
ing programming mode on initial power up to the thermostat
or when the device address is set to zero. This will speed up
the installation process and ease configuration.
Device Address — In order to communicate with the
network and receive broadcasts from the network, the moni-
tor thermostat must have an address. Each device on each
communication bus must have an unique address. The moni-
tor thermostat utilizes the network to:
• adjust configuration
• to gather data from the associated bypass controller and
zone controllers
• to receive additional information necessary to control its
zone and system
• to distribute instructions and information to the associated
bypass controller and zone controllers
• to control operation of the system heating/cooling
equipment.
The Device Address option allows the monitor thermostat
to establish an identity on the Carrier Comfort Network for
transmitting and receiving information. The device address
is set in category 8, option 1. The factory setting is 0. Use
the left set point buttons to raise and lower the device ad-
dress until the correct address is shown on the monitor ther-
mostat. The thermostat will not run without a device address.
