Heat Pump Heating Airflow; Cooling Airflow - Observer TSTAT0101SC Installation Manual

Heat Pump Heating Airflow

COMFORT (default) ­­ Heat Pump airflow is varied depend­
ing on outdoor temperature to maximize comfort.
EFF 325 ­­ Fixed airflow used to achieve specified ratings.
This is nominally 325 CFM/ton, but will vary if a 2­­stage out­
door unit is used.
EFF 350 ­­ Fixed airflow used to achieve specified ratings.
This is nominally 350 CFM/ton, but will vary if a 2­­stage out­
door unit is used.
MAXIMUM ­­ 400 CFM/ton.

Cooling Airflow

COMFORT (default) ­­ cooling airflow is varied depending on
humidity and temperature demands settings. This selection en­
ables the full dehumidify and comfort capabilities of the system.
When COMFORT is not selected, the unit will not run reduced
airflows for dehumidification.
EFF 325 ­­ fixed airflow used to achieve specified ratings –
no dehumidification airflow reduction. This is nominally 325
CFM/ton, but will vary if a 2­­stage outdoor unit is used.
EFF 350 ­­ fixed airflow used to achieve specified ratings –
no dehumidification airflow reduction. This is nominally 350
CFM/ton, but will vary if a 2­­stage outdoor unit is used.
