h. Setting a High CO
2
Alarm Limit (tracking alarm)
The high CO
2
alarm limit is the deviation from the CO
2
set-
point which will cause a high CO
2
alarm. The setpoint is vari-
able from 0.5% to 5.0% CO
2
above setpoint. The factory set-
ting is 1.0% CO
2
above setpoint. When activated, the CO
2
valve
is disabled.
1. Press the Mode key until the Configuration indicator
lights.
2. Press the right arrow until CO2 HI LMT X.X is dis-
played in the message center.
3. Press up/down arrow to change the high CO
2
alarm
limit.
4. Press Enter to save the high CO
2
alarm limit.
5. Press the Mode key to return to run mode or right/left to
go to next/previous parameter.
i. Enabling CO
2
Alarms to Trip Contacts
High and Low CO
2
alarms can be programmed to trip the
remote alarm contacts. A setting of ON activates this ability. A
setting of OFF will not allow CO
2
alarms to trip the contacts.
The factory setting is ON.
1. Press the Mode key until the Configuration indicator
lights.
2. Press the right arrow until CO2 RELAY ON/OFF is dis-
played in the message center.
3. Press up/down arrow to toggle the setting ON or OFF.
4. Press Enter to save the setting.
5. Press the Mode key to return to Run mode or right/left
to go to next/previous parameter.
j. Setting a Low RH Alarm Limit (tracking alarm)
The low RH alarm limit is the deviation from the humidity
setpoint which causes a low RH alarm. The setpoint is variable
from -5 to -20% RH. The factory setting is -10%RH.
1. Press the Mode key until the Configuration indicator
lights.
2. Press the right arrow until RH LO LMT -XX is dis-
played in the message center.
3. Press up/down arrow to change the RH low alarm limit.
4. Press Enter to save the RH low alarm limit.
5. Press the Mode key to return to Run mode or right/left
to go to next/previous parameter.
e. Setting a Low Temperature Alarm Limit
(tracking alarm)
The low temperature alarm limit is the deviation from the
temperature setpoint which causes a low temp alarm. The low
temp alarm is variable from one-half degree to five degrees
below setpoint. The factory setting is 1° below setpoint. A
minus sign (-) in the display indicates that the alarm setting is
below the setpoint.
1. Press the Mode key until the Configuration indicator
lights.
2. Press the right arrow until TEMP LO LMT -X.X is dis-
played in the message center.
3. Press up/down arrow to change the low temp alarm
limit.
4. Press Enter to save the low temp alarm limit.
5. Press the Mode key to return to Run mode or right/left
to go to next/previous parameter.
f. Enabling Temperature Alarms to Trip Contacts
The high and low temperature alarms can be programmed
to trip the remote alarm contacts. A setting of ON activates this
ability. A setting of OFF will not allow the temp alarms to trip
the contacts. The factory setting is ON.
1. Press the Mode key until the Configuration indicator
lights.
2. Press the right arrow until TEMP RELAY ON/OFF is
displayed.
3. Press the up/down key to toggle the setting ON/OFF.
4. Press Enter to save the setting
5. Press the Mode key to return to Run or the right/left
arrow key to go to next/previous parameter.
g. Setting a Low CO
2
Alarm Limit (tracking alarm)
The low CO
2
alarm limit is the deviation from the CO
2
set-
point which will cause a low CO
2
alarm. The setpoint is vari-
able from 0.5% to 5.0% CO
2
below setpoint. The factory set-
ting is 1.0% CO
2
below setpoint. A minus sign (-) in the display
indicates that the alarm setting is below the setpoint.
1. Press the Mode key until the Configuration indicator
lights.
2. Press the right arrow until CO2 LO LMT -X.X is dis-
played in the message center.
3. Press up/down arrow to change the low CO
2
alarm limit.
4. Press Enter to save the low CO
2
alarm limit.
5. Press the Mode key to return to Run mode or right/left
to go to next/previous parameter.
