HP Combi Flow is optionally available with an integrated mains switch-disconnector and front mounted control switch and
potentiometer. This allows the drive to be operated directly from the front control panel, whilst also providing for options such as Hand
/ Auto or Local / Remote Control etc.
The integrated switch in IP66 Outdoor models operates in parallel with drive terminal 2 (T2) and terminal 3 (T3) as digital input 1 and
digital input 2. By default, the integrated switch is enabled.
