MUI Alarm History Reporting
If a fault occurs the fault will be recorded in history for
display on the medium user interface in the History Menu.
Each fault type will be displayed in the history menu with
a number between 0 and 3. A reading of 3+ will mean that
fault has occurred more than three times in the past. The
history menu can be cleared with a power cycle only. Alarm
date and time are not included in the history.
Inputs and Outputs Configuration
Field Selectable Options
Freeze Detection Limit Set Point (BI-5)
The freeze detection limit set point input allows you to
adjust the freeze detection limit set point (AI-5). When the
jumper is installed on BI-5 (Wire #24) the freeze detection
limit set point is factory set for 30°F [-1°C]. When the
jumper on BI-5 (Wire #24) is removed the freeze detection
set point will be 15°F [-9°C].
Accessory Outputs (BO-7 and BO-8)
Accessory Output 1 will be energized 90 seconds prior to
the compressor output being energized. Accessory Output
2 will be energized with the blower output (BO-1). When
the corresponding compressor output is turned off the
accessory output will be deactivated immediately. These
outputs are selectable for normally open or normally closed
operation through the Medium User interface or through the
Building Automation System.
