5.6 COOLING DELAY PROFILES (-)H1V
The (-)H1V air handlers are shipped with a default 30 second blower OFF delay profile for
maximum efficiency.
IMPORTANT: Blower ON delay profiles are not used in heating mode.
5.7 COOLING MODE DEHUMIDIFICATION (-)H1V (PASSIVE: FACTORY
PROGRAMMED PROFILES)
Factory board settings will provide general overall performance under average conditions.
Use these Advanced Profiles to optimize performance and to add soft motor operation.
Please be sure that you check for correct airflow and adjust refrigerant charge based on your
Maximum Capacity and Airflow using the Factory AIRFLOW SETTINGS. Switches 1 and 2
should be set for the tonnage and airflow requirement for the system.
Advanced Airflow set-
tings will, in most cases, greatly reduce airflow to the system and change the system’s Latent
and Sensible capacity splits. The control board flashes CFM to the nearest 50 CFM calculat-
ed.
We suggest that trouble-shooting be done with switches in the factory position for
verification of refrigerant charge and airflow through the duct system.
