Continuous mode (factory default) – Fan operates as long as the control supply is connected to terminals 1-
3. Leave the internal jumper connected to the left terminal of JI (marked A in the drawing).
External control mode – Fan operates when the control supply is connected to terminal 2. Connect the
internal jumper to the middle terminal of JI terminal (marked B in the drawing). For use without bypass,
connect the fans before giving the start command and disconnect at least 5 minutes after giving the stop or
soft stop command.
Automatic mode – Whenever the start or stop signals is given the fan operates for approximately 5 minutes.
