Getting The Most From Your Home Ventilation System - Honeywell ER90 Owner's Manual

GETTING THE MOST FROM YOUR HOME VENTILATION SYSTEM

FRESH AIR CONTROL
The low voltage remote fresh air controls (ER100/200 only) allow conve-
nient operation of the ventilation system from the living area of your home.
The control performs the following four functions:
1. A two-position HI-LO range switch lets you place the ventilator into
LO or HI speed range. Only certain models have this feature.
2. The control knob allows selection of continuous ventilation rates
within the pre-selected HI or LO speed range.
3. This same knob is used to place the ventilator into the AUTO mode.
In AUTO, the blower is operated by the dehumidistat and/or
override switches that can be installed as options with your Home
Ventilation System.
4. An indicator light above the HI-LO switch verifies operation of the
unit.
MOISTURE CONTROL
Continual operation of the ventilation is recommended for optimum
reduction of indoor air pollution and control of humidity. Increased
moisture removal will always occur at maximum ventilation rates. This
setting should be used when first occupying a newly built home to
remove excess moisture from new wood, plaster, cement and other
moisture absorbing construction materials. If your system is wired
to a dehumidistat, preselected moisture levels can be maintained
automatically. Severe moisture conditions can be controlled with the
sensible energy transfer wheel when the indoor air contains more
moisture than the outdoor air.
REMOTE OVERRIDE SWITCH FUNCTIONS
Your ventilation system may incorporate one or more remotely located
switches to activate bathroom ventilation, a dehumidistat, or any combina-
tion of these or other ventilation functions. A remote switch in the ON
position will cause the ventilator to operate at high speed until the override
switch is turned off. The ventilator will automatically return to its previous
setting on the fresh air control. The remote override switch, in combination
with the AUTO mode, is especially useful for intermittent bathroom
exhaust when continuous ventilation is not required. Continuous operation
is recommended except when the home is unoccupied, or when proper
ventilation is provided by other means like open doors and windows.
