output-1 type
OFF (0): Disable
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.

output)

Retransmission output-2 is available when the type of control
output is not “current” or “voltage pulse.” The output is
provided via terminals 16 and 17.
