When congurating OVR option on the LCD screen, choose among these 3 congurations: BAL (the unit remains balanced
while providing maximum airow), PER (the unit is slightly unbalanced since the distribution motor is in MAX speed while
allowing maximum exhaust ventilation) and DIS (the unit is unbalanced since air distribution is constant despite a higher
need in exhaust ventilation).
NOTE : The auxiliary wall control can be used with a 3-wire connection by removing the LED signals. This optional wiring
will not allow an installation with more than 1 auxiliary wall control to properly synchronize their LEDs on an event
requested from a peer. Only the auxiliary wall control having requested the timer event will have the LEDs updated
accordingly.
