Please take note that this manual uses the following symbols to emphasize
particular information:
NOTE: Indicates supplementary information needed to fully complete an instruction.
We welcome any suggestions you may have concerning this guide and/or the unit,
and we would appreciate hearing your comments on ways to better serve you.

WARNING
Identifies an instruction which, if not followed, might cause serious
personal injuries including possibility of death.
!
CAUTION
Denotes an instruction which, if not followed, may severely damage the unit
and/or its components.
CAUTION
Make sure at all times that the outside hood is free from any snow during
the winter season. It is important to check your unit during a big snow
storm, so it doesn’t draw in any snow. If this is the case, please operate the
unit in the recirculation mode, or turn it OFF for a few hours.
Do not use your HRV during construction or renovation of your house or
when sanding drywall. This type of dust may damage your system.
Since the electronic control system of the unit is incorporated with a
microprocessor, it may not operate correctly because of external noise or very
short power failure. If this happens, unplug the unit and wait approximately
10 seconds. Then, plug the unit in again.

All units are equipped with an integrated control, located under the unit, on the
recessed side of electrical compartment. Plug the unit. Use the push button (1) to
control the unit. The LED (2) will then show on which mode the unit is in.
Refer to table below to see how to operate the unit using its integrated control.
If a problem occurs during the unit operation, its integrated control LED (2) will
blink. The color of the blinking light depends on the type of error detected. Refer to
Section 4 Troubleshooting
on last page for further details.

When the outside temperature is below -5°C (23°F), recovery of heat creates frost
in the core.
To maintain its proper operation, the unit is programmed to defrost the recovery
core. The defrost frequency varies according to the outside temperature.
During the defrost cycle, the unit shifts to maximum speed and the dampers close.
After defrosting, the unit returns to the operating mode selected by the user.

Controls (cont’d)
BOOT SEQUENCE (90H-V AND 60H NOVO+ ONLY)
The unit boot sequence is similar to a personal computer boot sequence. Each
time the unit is plugged after being unplugged, or after a power failure, the unit
will perform a 30-second booting sequence before starting to operate. During the
booting sequence, the integrated control LED will light Green (unit set in
normal defrost) or AMBER (unit set in extended defrost) for 5 seconds, and then
will shut off for 2 seconds. After that, the LED will light RED for the rest of the
booting sequence. During this RED light phase, the unit is checking and resetting
the motorized damper position. Once the motorized damper position completely
set, the RED light turns off and the booting sequence is done.
NOTE: No command will be taken until the unit is fully booted.

position. Once the motorized damper position completely set, the RED light turns
off and the booting sequence is done.
