Blower Speed Tap Description
Tap 5 - High Speed - Cooling or Heat Pump Operation
Tap 4 - Med-High Speed - Cooling or Heat Pump Operation
Tap 3 - Medium Speed - Cooling or Heating Operation
Tap 2 - Med-Low Speed - Heating Operation
Tap 1 - Low Speed - Constant Circulation Operation Only.
Tap 1 air circulation is around 200 CFM. This is not enough
air flow for heating, cooling or heat pump operation. If Tap 1
is used for cooling the evaporator will freeze up. If Tap 1 is
used for heating with electric heat the limits will open in a
very short time frame.
DO NOT USE SPEED TAP 1 FOR HEATING OR
COOLING!
