2.0 Functions
Three different setpoint settings can be issued via the three-step switch. Each step
(S1-S3) is freely adjustable via a separate potentiometer from (...
see table below ) Volts
(with a Phillips type screwdriver, Ø 3 mm).
The connection of a weekly timer (WSUP, WSUP-S, accessories) for switching from
3-step daytime mode to e.g. night mode is also possible. The night/reduction mode is
freely adjustable via an additional potentiometer (A1) from 0 to 10 V DC.
Only EC fans or frequency inverters, which provide at least 1.5 mA with 10 V power
supply (controller internal consumption), may be connected.
Total current = Internal consumption (controller) + fan load current
(load current depends on load of 0-10 V fan input)
All three potentiometers S1, S2 and S3 are set to left stop when delivered.
The potentiometers must be adjusted to local requirements.

The Three-Step Switch SU / SA has 4 potentiometers:
