• Performance levels can be verified at both extract and supply air valves using an appropriate method
such as a rotating vane anemometer and air cone kit.
• Refer to performance graph for ComfoAir 155 CM airflow characteristics
(See Section 3.1.8).
Note: All settings are stored within the ComfoAir 155 CM unit’s memory and should NOT be lost in the
event of a power failure. When power is restored, the unit should revert to normal running with all
settings unchanged. Likewise, reminder indicators are NOT reset.
