Description
RUN, WAIT: Take the current flow rate as the
switch point SP or SP2.→  12,  18
Enter value 0 to 95 % in increments of 1 %.
Factory setting: 40 %

Value must be at least 5 % smaller than
the switch point (SP or SP2).
Or optionally for RSP2:
Enter value –20 to +80 °C (–4 to +176 °F) in
increments of 1 °C (1 °F) if the switching mode
MODE is set to temperature TEMP.

Value must be at least 5 °C (9 °F)
smaller than switch point 2 (SP2).
Factory setting: 50 °C
Can be set anywhere between
0 to 99 s in increments of 1 s.
Factory setting: 0 s
Can be set anywhere between
0 to 99 s in increments of 1 s.
Factory setting: 0 s
Description
Output FLOW: flow rate or TEMP:
temperature

If TEMP is set, the measuring range is
fixed at –20 to +85 °C (–4 to +185 °F) .
Factory setting: FLOW
Current value in the event of an error:
MIN = ≤ 3.5 mA
MAX = ≥ 21.7 mA
HOLD = last current value
Factory setting: MAX
Output switching mode FLOW: flow rate or
TEMP: temperature
Factory setting: temperature (TEMP)
Temperature unit selection (°C or °F)

Function is only visible if the switching
mode MODE is set to temperature
TEMP in the 2nd output.
Factory setting: °C
