Fan Speed Response Verification
1. After performing controller specific commissioning,
observe the display on the motor control board with the
power on, to the unit. The motor control board display
should display a looping status indicator as follows:

• The indicator is unit-specific and may indicate "Off"
at this point; refer to thermistor function for more
information.
• A representative fan speed of "1080" rpm are shown in the
example below. Each unit is factory-configured differently
and will have different settings for different fan speeds.
2. While the unit remains on, exercise the fan controls on the
unit, either directly or indirectly through request for unit
heat/cool. Observe the fan spinning, and then observe the
fan display on the motor control board. It should display a
looping status indicator as follows:
For a size 200, 300, 400, 600, or 800 unit (using typical unit
operating fan speeds):

This his function protects settings on the board that
affect the safety of the electric heat system, and limit
FLA
the maximum current the motor will draw under any
operating condition.
This function shortens the ramps for faster unit
off
commissioning and auto-resets to off after
approximately 15 minutes of power-on operation.

3. OPTIONAL:
While the fan is running, if practical, change the fan speeds
and observe the display temporarily indicate:
Exercise all fan speeds to ensure positive unit response
and to validate any field wiring.

To aid in commissioning of the unit, for approximately
10–15 minutes, the ramps will be shortened to quickly
observe proper unit behavior and response to speeds.
