The setpoint for each mode must be within the following ranges:
• Supply Air - 75.0°F (See “Air Controls” on page 23.)
• Containment - 100.0 Pa (See “Air Controls” on page 23.)
Configure thresholds
A threshold is used to trigger an alarm. For example, if you want to be notified when the supply
air temperature exceeds 32°C (90°F), then set the supply temperature high threshold to 90°F.
The controller will generate an alarm when the supply air temperature exceeds the threshold.
The thresholds may be viewed or changed from this screen. The device password is required
to change the threshold setting.
• Contain DP High - 00.0 Pa - Can be set between the Containment Setpoint and DP
Sensor Max (see “Air Setup” on page 24)
N
OTE: Once the alarm is triggered, the differential pressure must fall below half way
between the Contain DP High threshold and the Containment Setpoint for the alarm to
clear.
• Contain DP Low - 00.0 Pa - Can be set between DP Sensor Min and Contain DP High.
• Return Temp High - Can be set between Return Temp Low threshold and (212°F).
• Return Temp Low - Can be set between -40°F (-40°C) and Return Temp High threshold.
• Supply Temp High - Can be set between Supply Air Setpoint (see “Air Controls” on
page 23) and 100°C (212°F).
• Supply Temp Low - Can be set between -40°C (-40°F) and Supply Temp High
threshold.
