Red light is flashing.
There is not enough fresh air delivered
to meet the requirements of the selected

TIPS:
Ventilation control reads new dial setting only
when test button is pushed or power is cycled.
To ensure dial settings are read, push test
button after any changes are made.
For single bedroom homes, set the bedrooms
dial to 2 (this may result in more ventilation than
the minimum required).
For homes having more than five bedrooms
and only a single ventilation system, set the
bedrooms dial to 5 (this may result in less
ventilation than the minimum required).
For conditioned square feet, set area (sq ft) dial
to the nearest value.
For airflow, set airflow (cfm) dial to the nearest
value.
Vaulted ceilings do not need to be considered
when setting this control.
For homes with multiple systems: Honeywell
recommends a ventilation control and fresh
air intake for each system. Measure ventilation
airflow for each system independently. Refer to
Multi-system Setup Example for further details.
