Application Considerations
Electrical Power / Airflow Switch
The Honeywell Enhanced Air Cleaner should only be powered when airflow is present.
– These models are designed for use with an air handler and are equipped with an airflow
1620/2020/2520
switch (see Fig. 1), which provides power only when the air handler blower is operating. These models are
designed to be powered from a 208 to 230 VAC single phase power source.

1625/2025 – The furnace control EAC terminals provide power to the unit only when the furnace blower is
operating. These models are designed to be powered from the electronic air cleaner (EAC) terminals on a
furnace control board. If EAC terminals are not available, an alternative airflow sensing mechanism must be
used to ensure the Honeywell Enhanced Air Cleaner is only powered when airflow is present. Contact your
local Honeywell distributor for information on alternatives.
