Figure 13 - Airflow and Fan Selection
The cooling system manufacturer’s instructions must be checked
for required air flow. Any electronic air cleaners or other devices
may require a specific airflow; consult installation instructions of
those devices for requirements.
3. Knowing the modular blower model, locate the high stage
cooling air flow charts in the Specification Sheet applicable
to your model. Look up the cooling air flow determined in
step 2 and find the required cooling speed and adjustment
setting.
Example: A MBVC1200 modular blower installed with a
2.5 ton air conditioning system. The air flow needed is 1000
CFM. Looking at the cooling speed chart for MBVC1200,
find the air flow closest to 1000 CFM. A cooling airflow of
1000 CFM can be attained by setting the cooling speed to
“C” and the adjustment to “Normal” (no adjustment).
4. Locate the blower speed selection DIP switches on the
integrated control module. Select the desired “cooling”
speed tap by positioning switches 1 and 2 appropriately. If
airflow adjustment is required, set dip switch S8 (trim
enable) to ON (trim enable default is off). Then select the
desired “adjust” tap by positioning switches S3 and S4
appropriately. Refer to the following figure for switch
positions and their corresponding taps. Verify CFM by
counting the number of times the green CFM LED blinks.
5. Continuous fan speeds that provide 25, 50, 75, and 100%
of the furnace’s maximum airflow capability are selectable
via dip switches S12 and S13.
If the furnace’s maximum airflow capability is 2000 CFM
and 25% continuous fan spped is selected, the continuous
fan speed will be 0.25 x 2000 CFM = 500 CFM.
6. The multi-speed circulator blower also offers several custom
ON/OFF ramping profiles. These profiles may be used to
enhance cooling performance and increase comfort level.
The ramping profiles are selected using DIP switches 5 and
6. Refer to Figure 14 for switch positions and their
corresponding taps. Refer to the bullet points below for a
description of each ramping profile. Verify profile selection
by counting the green CFM LED blinks and timing each step
of the ramping profile.
