The main button works following this sequence:
Click 1 = RECIRC (if available)
Click 2 = INT
Click 3 = MIN
Click 4 = MED
Click 5 = MAX
Click 6 = OFF
and so on
The indicator lights up per the selected mode.
RECIRC
—Recirculate air inside the house at MAX speed. Not
available on all units.
INT
—Within a one hour period, the system will operate in MIN speed
for 20 minutes.
MIN/MED/MAX
—Continuous exchange ventilation at selected speed.
• 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. The AUTO indicator
will light up and the system will operate as follows:
• Less than -25°C (-13°F) = 10 min/hr
• -25°C (-13°F) to -7°C (19°F) = 20 min/hr
• -7°C (19°F) to 10°C (50°F) = 40 min/hr
• 10°C (50°F) TO 25°C (77°F) = MIN speed
• 25°C (77°F) to 28°C (82°F) = 30 min/hr
• 28°C (82°F) to 33°C (91°F) = 20 min/hr
• Above 33°C (91°F) = 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 period, it
means that the communication cannot be established with the
ventilation unit. Make sure wires are correctly connected to the wall
control and unit terminals (refer to step 7).
