HOLIDAY SCHEDULES
The monitor thermostat supports holiday scheduling. Eigh-
teen different holidays can be user-defined. Each holiday has
a start date (month and day) and a duration. When a user-
defined holiday occurs, the monitor thermostat follows the
holiday schedule defined in the occupancy periods.
To define a holiday, advance to category 10. Each option
(holiday schedule) has 2 screens. The first option screen shows
the month and day. The second option screen shows the du-
ration. The default values are 0 for each schedule. Press the
select button on the first screen to modify the month and
day. The month will flash. Use the left set point buttons to
scroll through the months. January is 1. February is 2, and
so on. The range of acceptable values is 0 to 12. Set the month
to 0 to disable the holiday schedule.
Once the month has been selected, press the select button.
The day will flash. Use the left set point buttons to scroll
through the days. The range of acceptable values is 0 to 31.
Set the day to 0 to disable the holiday schedule. Press select
again to return to the option selection screen. Toggle to the
second screen of option 10.1 by pressing the upper left set
point button. Press the select button. The duration will flash.
The duration is the number of days the holiday schedule will
be active. The range of acceptable values is 0 to 99. Set the
value to 0 to disable the holiday schedule.
Options 10.1 through 10.18 are configured in the same
manner.
ALARM OPTIONS
The alarms options of the monitor thermostat are respon-
sible for transmitting alarms on the CCN (Carrier Comfort
Network). A specified device (such as the Building Super-
visor) on the CCN records the alarms from all devices and
uses this data to produce alarm messages. The monitor ther-
mostat detects successful transmission of the alarm and will
retry if there is a communication failure. If the alarm is suc-
cessfully transmitted, the monitor thermostat will disable the
alarm. If the alarm persists, the monitor thermostat will re-
issue the alarm after expiration of the re-alarm time.
Equipment Priority — The Equipment Priority func-
tion tells the error recording device the priority of the device
that is sending the alarm. The priority determines which alarms
are shown first and which alarms are deleted when the alarm
memory is full. To set the option, configure category 11,
option 1. The range is 0 to 7, where 7 is the lowest priority.
The default value is 7 (monitor thermostat priority).
It is recommended that this value not be changed. Equip-
ment damage can occur if low priority values are given
to high priority alarms.
Communication Failure Retry Time — The Com-
munication Failure Retry Time option configures how long
the monitor thermostat will wait before re-sending an alarm
that was not received by a device. The option is configured
in category 11, option 2. The range of acceptable values is
1 to 240 minutes. The default is 10 minutes.
NOTE: When no alarm acknowledger is available the com-
munication failure retry time should be set to 240.
Re-Alarm Time — The Re-Alarm Time option config-
ures how long the monitor thermostat will wait before
re-sending an alarm after the alarm message has been
received by an alarm acknowledger. When the condition
returns to normal, the alarm will no longer be sent. The
option is configured in category 11, option 3. The range of
acceptable values is 1 to 255 minutes. The default is 30 min-
utes. A value of 255 disables re-alarming.
Alarm Routing Control — The Alarm Routing Con-
trol option determines which devices on the CCN will re-
ceive and process the alarm information. This option cannot
be configured from the monitor thermostat. The default value
is 11000000. This value sends/marks alarms for building su-
pervisors and autodial gateways. A value of 10000000 sends
alarms to the building supervisor. A value of 01000000
sends alarms to the autodial gateway. A value of 00010000
sends alarms to the printer interface. A value of 00000000
disables all alarms going out on the CCN. The option is con-
figured through Carrier network access software using the
ALARMDEF configuration table.
Alarm System Name — The Alarm System Name op-
tion identifies the alarm system on the CCN. This option can-
not be configured from the monitor thermostat. The default
name is 33CSVM. The option is configured through Carrier
network access software using the ALARMDEF configura-
tion table.
LOADSHED
The Loadshed module is a device on the network that moni-
tors system electrical energy usage. A field-supplied watt-
meter is required. The module can be programmed to send
out Redline and Loadshed commands to devices on the net-
work when energy usage nears user-defined set points. These
devices are user-defined into Demand Limit Groups. The Red-
line and Loadshed commands cause the monitor thermostat
to turn off some or all stages of heating or cooling. When the
energy usage drops below a defined level, the Loadshed re-
leases the command. The Demand Limit Group Number
option (category 13, option 1) defines which group the moni-
tor thermostat will be in.
When the Loadshed sends a Redline command to the moni-
tor thermostat, the monitor thermostat will: 1) turn off sec-
ond stage heating or cooling operation if the second stage is
currently operating; 2) not allow second stage heating or cool-
ing to come on; and 3) send a message to all associated zone
controllers to disable supplemental heat operation.
When the Loadshed sends a Shed command to the moni-
tor thermostat, the monitor thermostat will: 1) turn off first
and second stage heating or cooling operation if the first or
second stages are currently operating; 2) not allow heating
or cooling to come on; and 3) send a message to all asso-
ciated zone controllers to disable supplemental heat opera-
tion. System mode is released to allow zone controllers to
operate in local mode.
To configure the Demand Limit Group Number option,
set category 13, option 1. The range of values is 0 to 16. If
the option is set to 0, the monitor thermostat will not be part
of the Loadshed group operation. If the option is set from 1
to 16, the monitor thermostat will receive Loadshed com-
mands for that group. The default is 0. For more informa-
tion, refer to the Loadshed configuration manual.
ALARM DESCRIPTION
This section describes the major alarm types that are avail-
able within the system. The alarm types are: space tempera-
ture alarm (comfort trend), discharge air temperature alarm,
fan status alarm, filter status alarm, IAQ status alarm, com-
munication failure alarm, and stuck gas valve alarm.
The section describes each alarm in detail: what control-
lers it works with; the sensors required for the alarm to be
activated; and how the alarm is configured, disabled, and nor-
malized. The description provides information on how the
alarm is applied and the necessary hardware required for proper
operation.
