Test’ Mode
the software shall select speed setting 10 for low-speed,
11 for medium-speed, and will select speed setting 12 for
high speed. If only one selection is set to ON, that selection
will set the low-speed blower setting, the medium-speed
setting will be 11, and the high-speed setting will be speed
12. The maximum low-speed setting will be speed 10
and the minimum high-speed setting will be speed 3. In
addition there is a low limit setting in the software to prevent
the variable speed ECM blower speed from being set below
acceptable limits for each unit size.
Emergency Heat/Network Enabled Output (BO-5)
This output is set from the factory to enable/disable
emergency heat. If a problem occurs with the unit resulting
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
blower proving input BI-6 (Blower proving sensors must
be field supplied and installed). BI-6 must be connected
to PB2 position 3 (see unit schematic) in the field if no
blower proving sensor is desired. There is a configurable
parameter available through a BAS network that must be
enabled if this output is to be commanded over the BAS
network.
NOTE:
For auto switch over, BO-5 must be set to
"Emergency" using the MUI.
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 Set Point (BI-5)
The freeze detection set point input allows you to adjust
the freeze detection set point (AI-5). When the jumper is
installed on BI-5 (Wire #24) the freeze detection 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 MUI or through the BAS.
