When confi gurating OVR option on the LCD screen, choose among these 3 confi gurations: BAL (the unit remains balanced
while providing maximum airfl 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.

LECTRICAL ONNECTION TO
A miswiring that sends a 24 VAC signal to the 6-position terminal block (OVR, LED, 12V, D-, D+, GND) could
permanently damage the control circuit. Verify carefully wire connections before powering-up the unit.
