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.
