15-min Timer
- The 15-minute remote timer is typically installed in areas where
contaminated such as moisture and odors, are produced. Simply push the
button and the HRV will activate to high speed for 15 minutes. Up to 5
electronic timers can be installed throughout the building at a distance of up to
500 feet (152 meters) from the HRV.
Air Quality Sensor
- The wall mount Air Quality Sensor (AQS) monitors indoor
air quality and activates the override mode when carbon monoxide, formaldehyde,
benzene, volatile organic compounds and other pollutants are detected. The
unit will then return to normal mode once the air pollutants are reduced to a
pre-determined lower level.
* This control is not a warning device.
Dehumidistat II
- The wall mount dehumidistat II offers the same features of the
dehumidistat I plus additional off/on control for the HRV. Dial illuminates when
in override mode.
Dehumidistat I
- The wall mount dehumidistat monitors the humidity level in the
area it is installed. When the humidity level rises above the desired set-point,
the HRV will activate to high speed/override mode. Once the humidity level
returns to desired condition, the unit will return to the normal mode.
To avoid window condensation:
• It is not necessary to
change the humidity control
every day. Monitor the
average weekly
temperature or experiment
with various settings until
you find a level that is
comfortable for you. Adjust
the control when needed.
PRACTICAL
TIPS
* All controls are low voltage. 18 to 24
gauge wire is recommended.
OPTIONAL REMOTE CONTROLS
OPERATION
(CONT'D)
NOTE:
A dehumidistat is ideal for
use in energy efficient
houses where indoor
humidity (during the
heating season) is higher
than outdoor levels. High
humidity is a major cause
of structure damage and
IAQ problems such as mold
and mildew.

OPTIONAL INTELLITEK CONTROL
NOTE:
When an Intellitek control
is installed, the rocker
switch located on the right
hand side of the HRV will
be automatically
deactivated giving the user
complete control from
wherever he/she wishes to
mount the control pad.
NOTE:
The override speed cannot
be set at a fan speed lower
or equal to the normal
operating fan speed. For
example, if the unit is
normally operating at a
medium fan speed, the
override fan speed will be
automatically set to high.
NOTE:
5MR model, changing the
override speed will change
default override speed for
other external controls.
EXAMPLES:
If on the 5MR control, you
have set the override
control at medium, and
you start an external
remote control (15 min.
timer), the unit will run at
medium speed for 15 min.
