Aquatherm fan/coil units provide the advantages of efficient hydronic heating in combination with either - horizontal left applications, but easily field convertible to horizontal right. These are not for counterflow application.
to maintain a predetermined level of airflow over a wide range of external static pressures, ensuring op- - tribution, better indoor air quality and better humidity control. The field wiring terminal block provides connection terminals for use with a standard dehumidistat. The fan coil will detect the dehumidistat contacts opening on increased humidity and reduce its airflow saving energy.
Note: Use of third party (First Company) air handlers with outdoor units will not allow registration upgrades from the standard manufacturers warranty on the outdoor unit.
