ECM2 Blower Operation
Fan speeds will be selected through the user interface or the facility management system. There will be a total of 12 speeds selectable with only three being selected at any one time. The lowest numbered speed selection set to ON will select the
ECM2 Fan air flow “Soft Switch Settings”
A set of 12 “soft switches” accessible through the user interface or building automation system are used to select the three fan speed settings for the ECM2 fan motor.
The 12 soft switches work in exactly the same way as the hardware switches used on the Premier control (Refer to Fan Performance Data - ECM2 Motor for proper settings). No more than three soft switches may be set to the “ON” position. The first “ON” switch (the lowest number switch) determines the “low speed fan” setting. The second de- termines the “medium speed fan” setting, and the third determines the “high speed fan” setting.

Emergency Heat/Network Enabled Output (BO5)
This output is set from the factory to enable/disable emergency heat. If a problem occurs with the unit result- ing in the compressor being locked out in heating mode, the control will automatically enable this output to turn on field installed electric heat. This output is interlocked with the fan proving input
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.
