Unit Operations
The first time the unit runs…
When the unit is first turned on, it will run at medium speed for 6 hours. During this initial 6-hour
period, it is important to allow it to run uninterrupted, since the unit will take readings that will be
important to determine the best operating speed that will, over time, get the most energy efficient
ventilation for the entire home and maximum reduction of relative humidity.
The HCS-BS and HCS-CS are pre-programmed to a default humidity setting of 55% which will result
in the best operation all year round.
After power outages or whenever the unit is powered down (unplugged) and powered up again
(plugged into the wall again), the unit reads the last recorded settings and will return to its regular
operation mode.
Note:
For the unit to function properly and to allow the unit to provide the best energy efficient
ventilation and humidity control, all windows, doors with access to the outdoor and vents to the
outdoor should be closed to prevent an excessive amount of outdoor air from entering directly into
the house.
Vacant Homes
Performance results are maximized when the building is occupied. If home is vacant for a prolonged
period of time, then the unit should be set to operate at low speed. A fresh air intake supply is
recommended via a small opening in a window upstairs or a supply vent such as the ASV-90.
Maintaining your HCS
The HCS Products do not require any internal maintenance. The only maintenance needed for your
HCS is a periodic vacuuming of the dust accumulation at the intake grilles or louvers located at the
bottom of the unit. For proper functionality do not store anything within a radius of 4 feet around the
base of the Humidex.
