7.2.4 3-point stepping controller (relay & relay)
ConF / Cntr: SP.Fn = 0 setpoint controller
C.Fnc = 4 3-point stepping controller
C.Act = 0 inverse action (e.g. heating applications)
ConF / Out.1: O.Act = 0 action Out.1 direct
Y.1 = 1 control output Y1 active
Y.2 = 0 control output Y2 not active
ConF / Out.2: O.Act = 0 action Out.2 direct
Y.1 = 0 control output Y1 not active
Y.2 = 1 control output Y2 active

For direct action of the 3-point stepping controller, the controller output action must be changed
( ConF / Cntr / C.Act = 1 ).
