Connecting the sensors
Cables with a minimum cross-section of 2 x 0.5 mm² can be connected to the terminals at the
back panel of the housing.
Connecting the actuators
Connect cables with at least 1.5 mm² suitable for damp locations to the terminals of the control-
ler output. The direction of travel needs to be checked at start-up.
4
Set mode switch to (+). Valves must open.
