Installation Instructions

• Profile C ramps up 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 C

also has a one (1) minute 100% OFF delay.

• 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 dipswitches 9, 10, and 11 for the installed heater

as shown in the table below. The adjust setting (already

established by the cooling speed selection) also applies 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.

If an electric heater kit has not been installed, set dip switches

9, 10, and 11 to any valid heater kit setting (see airflow table

for valid settings). This will prevent an Ec Error code from

being displayed.
