1: PV1, 2: SP1, 3: OUT1, 4: LPS loop power supply (15 V),
5: PV2, 6: SP2, 7: OUT2
Setpoints 5 to 7 are not available for single-loop control.
Retransmission output 1 is always provided via terminals 14
and 15.
In position proportional control, a valve opening signal (0%
to 100%) is transmitted if setpoint “3” is selected.
In heating/cooling control, an output value before allocation
to heating/cooling control (0% to 100%) is transmitted if
setpoint “3” is selected.
