USING THIS UNIT
YOUR VENTILATION SYSTEM
This balanced ventilation unit is designed to provide fresh air to your
home while exhausting stale, humid air. Thanks to its energy/heat
recovery module, the unit recovers a large proportion of heat or energy
that is part of indoor or outdoor air according to the seasons to improve
comfort and energy efficiency during the heating and the cooling
periods. With the new ventilation technology, this unit responds to the
variations in its environment in an autonomous way, ensuring to provide
a proper level of ventilation and air quality. This unit also features
automatic modes (AUTO or SMART) that manage autonomously the
required ventilation level as per indoor and/or outdoor conditions. In
colder areas, the unit will perform, at intervals, recovery module discreet
defrost to maintain performance and comfort.
INTEGRATED CONTROL
A200579
All units are equipped with an integrated control, located in front of the
electrical compartment. For more convenience, these units can be
controlled using an optional wall control or the furnace/AHU thermostat
equipped with external fan activation.
MODE SELECTION
1. To change the mode, use (+/-) to access the Mode screen. Press OK
to edit the mode and use (+/-) to change the mode (Standby, Min,
Max).
2. Press OK to confirm selection. The airflows will be displayed for
both MIN and MAX modes.
NOTE:
If an optional auxiliary wall control or the furnace/AHU
thermostat equipped with external fan activation is used, it overrides the
integrated control.
