4. External start/stop

The GENI module incorporates a digital input for an external contact. The
pump can be started and stopped via this input.
When started, the pump will operate with the setpoint set on the control
panel or with the R100.
Note: If the external contact is used, the connection between terminals 7 and
8 must be replaced by the external connection.
