Getting The Most From Your Fresh Air Ventilation System - Honeywell ER150 Perfect Window Owner's Manual

ER150 AND ER200 Perfect Window™ FRESH AIR VENTILATION SYSTEMS
months when the outside air contains more moisture than the inside air, the
dehumidistat should be turned off so that a call for drying of the inside air
doesn't result in additional moisture entering your home.
TIMER
For your convenience, Honeywell provides an optional timer control that can fit a wide
variety of needs, for example, exhaust humid air from the bathroom or kitchen (see the
timer instructions for selection and part numbers).
WALL SWITCH
A wall switch can also be used to switch your ventilator fan speed to high. The fan will
run at high speed until the wall switch is turned off.
When any remote device is activated the ventilator will run at high speed. All remote
devices must be in the off position to return the fan to the speed manually selected on
the rotary fan speed control knob.

HOW MUCH VENTILATION DO I NEED?
During the seasons that your windows and doors are closed (winter and summer if you
have air conditioning), the ventilator should operate continuously when the home is
occupied, and either continuously or intermittently when not occupied.
For most installations, the ventilator will normally be set to operate continuously on low
speed with the option of going to high speed as the need arises. For example, if you
are entertaining and there is a large number of people present (some may be
smoking), the ventilator should be switched to high speed.
