UNIT FIRST BOOT
PREPARATION
Follow these steps to ensure accurate measurements:
• Seal all the ductwork with tape. Close all windows and doors.
• Turn off all exhaust devices such as range hood, dryer and bathroom
fans.
• If the installation is in any way connected to the ductwork of the cold
air return of a furnace/air handler, make sure that the furnace/air
handler blower is ON. If not, leave furnace/air handler blower OFF.
AUTO-BALANCING PROCEDURE
1. Plug in the unit and wait for the maximum CFM to display on the
LCD screen. If the unit is colder than ambient temperature, it is
normal to experience up to a 60-second longer boot-up since the
motors need to preheat.
2. The maximum CFM will display on the LCD screen. Use (+/-) to
adjust the CFM and OK to confirm.
3. The minimum CFM will display on the LCD screen. Use (+/-) to
adjust the CFM and OK to confirm.
4. The house icon that flashes on the LCD screen indicates which side
currently limits the airflow (supply or exhaust). If the airflow
reached is not sufficient, the installer can improve the installation to
increase airflow.
INSTALLATION CONFIGURATION SELECTION
1. INS will display on the LCD screen. Choose among T-1, T-2, T-3,
T-4 or T-5 following the installation configuration (INSTALLING
THE DUCTWORK AND THE REGISTERS on p5).
