(1) One side of transformer, secondary is connected to signal common. Dedicated transformer is recommended.
(2) Quick Start Menu parameters shown, for additional capabilities see installation manual.
(3) Time for reaching 63% of reading at 25° C and 1 m/s airflow.
(4) Long term exposures to conditions outside normal range at high humidity may temporarily offset the RH reading (+3%RH after 60 hours.)
(5) Accuracy of CO2 reading may be reduced at temperatures below 14ºF (-10oC).
