Speed Control used as a Mode Control

When the LED indicator is green, the selector switch functions as a Mode Selector. The selections are:
• INTER (Intermittent): When the selector switch is in the intermittent position the unit will run only when there
is a call for ventilation by any external control. At that time the unit will run on high speed until the condition is
satisfi ed.
• CONT (Continuous): When the selector switch is in the continuous position the unit will run continuously on
low speed except when there is a call for override by any control.
• OFF: When the selector switch is in the off position the unit will not operate even when there's a call for
ventilation by an external control.

b. Press the (+) and (–) buttons simultaneously for 5 seconds until the LED indicator light turns
yellow, which indicates that you are in balancing mode.
When in balancing mode, the selector switch becomes the motor selector switch. The switch
positions become: INTER = Right motor (exhaust air), CONT = Both motors, and OFF = Left
motor (fresh air).
