NSTALLATION AND
The illustrations in this document are generic; your control appearance may be slightly different from the ones shown.
Electrical wiring must be done by qualifi ed personnel in accordance with all applicable codes and standards.
Before connecting wires, unplug the unit or switch power off at service panel and lock service disconnecting means
to prevent power from being switched on accidentally. Always wear safety glasses and gloves while performing
these instructions.
If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts to prevent condensation
formation inside and outside ducts, which could cause material damage and/or mold growth. Moreover, if fresh air
to building duct and/or stale air from building duct goes/go through an unconditioned space, the unit must be set
to operate continuously in cold conditions (below 10°C/50°F). Continuous air movement inside ducts will prevent
condensation formation. The unit can be stopped temporarily for maintenance and/or repair purposes in such
conditions. (Refer to section 2.2 from unit User and Installer Manual for more details.)
INSTALLATION


Temporarily place the control over the
hole and mark both mounting screw
hole positions.

Remove the control, drill both screw
holes (3/16" Ø) in wall and insert the wall
anchors (included).

Strip the end of the cable to access the 4 wires (about 3"). Strip the
end of each wire (about 1/4"). Connect the wires to the terminals,
regardless of the wire color. Note which wire color has been
chosen for each terminal. See illustration below.

•
Press the TURBO button to get 4 hours of ventilation in MAX
speed. The TURBO indicator will light up. Once the 4-hour
period is done, the system will operate according to the
previous setting.
• Press the AUTO button to let the system operate according to
outdoor temperature. The AUTO indicator will light up and the
system will operate as follows:
• Less than -25°C = 10 min/hr
• -25°C to -7°C = 20 min/hr
• 10°C to 25°C = MIN speed
• 25°C to 28°C = 30 min/hr
• 28°C to 33°C = 20 min/hr
• Above 33°C = 10 min/hr
•
If the maintenance indicator is lit, it means that the filter
needs to be cleaned or replaced. Once the filter is cleaned or
replaced, press the AUTO button for five seconds to reset the
maintenance indicator. If the maintenance indicator flashes, the
LCD screen on the unit will give the error code. Refer to the
Troubleshooting section in the ventilation unit user guide for
more information.

At unit first boot, AUTO and TURBO indicators blink alternately
for about 1 minute. If indicators continue blinking after this
