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:
          
   
    
Notes:
• 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):
        
    
    
For a size 1000 or 1200 unit (using typical unit
operating fan speeds):
        
     
    
Note: The
 indicator is unit-specific and may
indicate “Off” at this point; refer to thermistor
function for more information.
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.
Protect Funct
 
This function protects settings on the board that
affect the safety of the electric heat system.
Do NOT change this setting. This setting locks out
the following parameters from being changed, for
safe operation of the unit.

This function shortens the ramps for faster unit
commissioning and auto-resets to off after
approximately 15 minutes of power-on
operation.
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.
