CONTROLS FOR YOUR HOME VENTILATION SYSTEM
1. FRESH AIR CONTROL
Controls the air flow rate in the
system, allowing the home-
owner to change the air flow
rate as conditions in the home
change. To select the desired
air flow rate position, move the
knob on the controller to the
desired level. See Fig. 1.
2. DEHUMIDISTAT
Select the desired inside
humidity level for the home.
The dehumidistat will override
the fresh air control and cause
the Home Ventilation System
to operate at high speed until
humidity levels are reduced to
the humidistat setting. At this
point, the dehumidistat will turn
off and airflows will return to
the fresh air control setting. For
summer operation, set
dehumidistat to
OFF position.
3. MASTER SWITCH
This switch is located on the
unit cover. The switch turns off
the unit completely, disabling
the fresh air control,
dehumidistat and blowers. See
Fig. 2.
