Alarm Limit
High and Low temperature alarms can be programmed to trip the remote
alarm contacts.  A setting of ON will cause this, a setting of OFF will not
allow temp alarms to trip the contacts.  The factory setting is ON.
1. Press the Mode key until the Config indicator lights.
2. Press the right arrow until Tmp Rly XXX is displayed in the message
center.
3. Press the up/down arrow to toggle the setting ON/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.
The low CO
2
alarm limit (tracking alarm) is the deviation from the CO
2
setpoint that will cause a low CO
2
alarm.  The setpoint is variable from
0.5% CO
2
below setpoint to 5.0% CO
2
below setpoint. The factory setting
is 1.0% CO
2
below setpoint. A minus (-) in the display indicates that the
alarm setting is below the setpoint. 
1. Press the Mode Key until the Config indicator lights.
2. Press the right arrow until CO2 LO -X.X  is displayed in the message
center.
3. Press the 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. 
The high CO
2
alarm limit (tracking alarm) is the deviation from the CO
2
setpoint that will cause a high CO
2
alarm.  The setpoint is variable from
0.5% CO
2
above setpoint to 5.0% CO
2
above setpoint.  The factory
setting is 1.0% CO
2
above setpoint.

Setting a Low O
2
Alarm Limit
Enabling RH Alarms
to Trip Contacts
On units that have the RH option installed, a low RH alarm limit may be
entered.  The low RH alarm limit is the %RH in the cabinet that will
cause a low RH alarm.  The setpoint is variable from setpoint 0 to 90
%RH.  The factory setting is 0% RH, which disables the alarm.
1. Press the Mode key until the Config indicator lights.
2. Press the right arrow until RH Lo XX is displayed in the message
center.
3. Press the 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.
The low RH alarm can be programmed to trip the remote alarm contacts.
A setting of ON will cause this, a setting of OFF will not allow the RH
alarm to trip the contacts. The factory setting is ON.
1. Press the Mode key until the Config indicator lights.
2. Press the right arrow until RH Rly XXX is displayed in the message
center.
3. Press the up/down arrow to toggle the setting ON/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.
On models with a O
2
control system, O
2
alarms may be configured. The
low O
2
alarm limit (tracking alarm) is the deviation from the O
2
setpoint
that will cause a low O
2
alarm. The setpoint is variable from 0.5% O
2
below setpoint to 5.0% O
2
below setpoint.  The factory setting is 1.0% O
2
below setpoint. A minus (-) in the display indicates that the alarm setting
is below setpoint.
