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 satisfied.
• 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.

• ( ) and ( ) buttons: Used to adjust the continous speed setting.

Speed Control used as a Balancing Control

In balancing mode the LED indicator is yellow, and the selector switch functions as a Balancing Control

selections are:.
• INTER: Selects the exhaust air motor.
• CONT: Selects both exhaust and fresh air motors.
• OFF: Selects the fresh air motor.
NOTE: Continuous low speed is 50% of the set high speed.

a. Ensure that the speed control selector switch is in either the INTER or CONT position.
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).
