Protect Funct EEhhpptt FFLLAA
This function protects settings on the
board that affect the safety of the
electric heat system, and limit the
maximum current the motor will draw
under any operating condition.
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.

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:
MMttrr11 → 00 → MMttrr22 → 00 → FFSStt11 → OOffff → FFsstt22 →
OOffff → EEhhEEnn → OOnn
Notes:
• The
EEhhEEnn
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):
MMttrr11 → 11008800 → MMttrr22 → 00 → FFSStt11 → OOnn → FFsstt22 →
OOffff → EEhhEEnn → OOnn
For a size 1000 or 1200 unit (using typical unit
operating fan speeds):
MMttrr11 → 11008800 → MMttrr22 → 11008800 → FFSStt11 → OOnn → FFsstt22 →
oonn → EEhhEEnn → OOnn
Note: The EhEn 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:
rraammpp
Exercise all fan speeds to ensure positive unit
response and to validate any field wiring.
