HR150 AND HR200 Perfect Window™ FRESH AIR VENTILATION SYSTEMS

EXTERNAL REMOTE WALL CONTROL (DEHUMIDISTAT)
The dehumidistat (connected to your ventilator) is designed to control the operation of
the ventilator fan to help keep the humidity level in your home comfortable. If an
independent humidifier is installed and set at 30% (a normal indoor winter level) then
the dehumidistat (for the ventilator) should be set at least 10% higher, in this case
40%. With the ventilator operating on low speed and no one is home to produce
humidity, the humidifier will keep the humidity level to its setpoint. If the humidity levels
rise (due to occupant activity) above the 40% level, then the dehumidistat will
automatically increase the speed of the ventilator fan to high until the humidity level
falls below 40%.
TIMER
For your convenience, Honeywell provides a timer control that can fit a wide variety of
needs, for example, exhaust humid air from the bathroom or kitchen (see the
installation guide 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.
YOUR VENTILATOR MAY BE SET TO HIGH SPEED BY:
1. selecting the highest speed on the ventilator or
2. if the system includes an optional remote control, switch it to the ON position.
NOTE: To set the dehumidistat, refer to the previous section of this booklet. To oper-
ate other remote devices, refer to the device owner’s manual.
