• Profile D ramps up to 50% of the demand for 1/2 minute,
then ramps to 82% of the full cooling demand airflow
and operates there for approximately 7 1/2 minutes.
The motor then steps up to the full demand airflow.
Profile D has a 1/2 minute at 50% airflow OFF delay.

7. If an electric heater kit has been installed, determine
the heater kilowatt (kW) rating. Find the heater size in
the table below. Set dip switches 9, 10, and 11 for the
installed heater as shown in the Dipswitches - Electric
Heat Airflow figure below. The adjust setting (already
established by the cooling speed selection) also ap-
plies to the electric heater kit airflow. Thus, the electric
heater airflow is adjusted by the same amount. Verify
selected CFM by counting the green CFM LED blinks.
ELECTRIC HEAT TEMPERATURE RISE:
The heating mode temperature rise is dependent upon the
system airflow, the supply voltage, and the heat kit size (kW)
selected. Use the supply voltage/temperature rise tables
below to determine the temperature rise (
º
F).

NOTE: Upon start up in communicating mode the circuit board will display a “1 Flash” error code on the diagnostic LED
and an “Ec” HTR TO LARGE error at the communicating display. This is an indication that the dip switches on the control
board need to be configured in accordance with the Electric Heating Airflow Table on the following page of this manual.
Configuring the dip switches and resetting power to the unit will clear the error code.
