Defrost Modes
• Built-in self controlled electric preheating coil
(SSR-controlled).
• The unit preheat the outside air at a given set point at
which no frost will occur.The electric coil is Self controlled
and powered by the unit (single point power connection).
• Built-in liquid preheating coil.
• The unit preheat the outside air at a given set point
at which no frost will occur. A 0 to 10VDC control signal
is available to control external hydronic valves (supplied
by others).
• Fan exhaust defrost cycles.
• The unit monitors the outdoor air and when it reaches
below a specic temperature, the unit cycles the supply
air blower on and o for a specic duration to remove
any built frost inside the xed plate recovery core.
• Recirculation defrost cycles.
• The unit monitors the outdoor air and when it reaches
below a specific temperature, the unit cycles the
exhaust air blower and the recirculation damper on and
o for a specic duration to remove any built frost inside
the xed plate recovery core. During such cycles, the
unit will recirculate the air drawn from the building
directly back into the building.

Control Options
Dirty lters contact: A dry contact, available at the unit’s terminal
board, closes when the pressure drop accros a specic lter banks
reaches its nal pressure drop.
Blowers rotation detection: Unit stops if rotation if the pressure
increase in the supply air blower is null.
Free-Cooling Management: The unit measures and monitors
outdoor air temperature and when within a specic range, the
unit goes into free-cooling.
End switch on Dampers: Unit start-up conditionnaly to the
dampers openings.
BACnet compatible Controler: Unit is controlled using a BACnet
compatible controller. The controller can communicate with
either a:
• MS/TP connection or
• IP connection
Remote Displays:
Offered with command buttons or with touch screen (Only
available with the BACnet controller).
This device should be installed and
balanced by a specialized contractor in
ventilation services.

for 5 minutes after circuits disconnect have
been opened. The following electrical
components may not be electrically safe
immediately:
•
