Please note:
Settings 3 and 4 of the code cover enable the ducted exhaust of the pilot and breathable exhaust
air, when the valve terminal is not fitted with reversible 2x3/2−way valves from Festo. The seals
between the manifold plates and the valves must be fitted here in the relevant position (see
