Airflow is controlled /- 5% up to Max ESP shown with wet coil and standard 1” fiberglass filter.
Condenser hot water reheat equipped units are factory set to operate in stage 2 airflow.
JE-Series with Condenser Hot Water Reheat
All JE units have an ECM fan motor. The small amount
of additional pressure drop of the condenser hot water
reheat coil causes the ECM motor to slightly increase
RPM to overcome the added pressure drop and maintain
selected CFM up to the maximum ESP.
Unit minimum operating temperature when in the
dehumidification or cooling mode is 65°F DB. Operation
below this minimum may result in nuisance faults.
