*
CFM is ERV wheel rating. This may vary depending on unit cabinet pressure drop.
**
These CFM ranges are dependant upon blower motor selection.
Low Ambient Kit
(
LAK
) - Defrosts wheel when low ambient temp near the exhaust blower shows possible frost up.
Start-Stop-Jog
(
SSJ
) - provides a "free cooling" mode by stopping enthalpy wheel when temps are appropriate for free
cooling.
Motorized Outside Air
(
MOA
) damper - closes a damper on the outside air intake when the ERV is not in use.
Pressure Sensor
(
PS
) - Analog differential pressure gauge (Magnahelic) shows pressure drop across the wheel in
Inches of Water.
