15-min Timer
- The 15-minute remote timer is typically installed in areas
where contamination such as moisture and odors, are produced. Simply push
the button and the ERV will activate to high speed for 15 minutes. Up to 5
electronic timers can be installed in parallel throughout the building at a
distance of up to 500 feet (152 meters) from the ERV.
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 ERV. 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 ERV 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:
• If a dehumidistat or EDF
control is installed, the
humidity setting should be
raised to its highest setting
(e.g. 99% on EDF) when
using an ERV during warm
and humid months.
Otherwise, the ERV may
stay on HIGH speed,
bringing in more humid air
indoors.

TIPS
OPERATION
(CONT'D)
* All controls are low voltage. 18 to 24
gauge wire is recommended.
OPTIONAL REMOTE CONTROLS
*
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 ERV 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:
EDF5 model, changing the
override speed will change
default override speed for
other external controls.
EXAMPLES:
If on the EDF5 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.
