1-4 START
Start pressure (p
start
)
With these DIP switches the start pressure can be set
from 2.5 bar (250 kPa) to 6.0 bar (600 kPa) in steps
of 0.5 bar (50 kPa).
Example:
DIP switch 1 = "ON"
DIP switch 2 = "ON"
Start pressure = 2.5 + 0.5 + 1 = 4 bar
Start pressure = 250 + 50 + 100 = 400 kPa
See section 7.2.1 Starting and stopping conditions.

5 STOP = START + 1 BAR
Start/stop with 1 bar (100 kPa) differential
pressure
(This operating mode is only suitable for systems with
a pressure tank).
When the DIP switch has been set to "ON", the pump
stop pressure will be equal to p
start
+ 1 bar (100 kPa).
See section 7.3 Start/stop with 1 bar (100 kPa)
differential pressure.
In systems without a pressure tank, the DIP switch
must be set to "OFF".

6 AUTO RESET
Automatic resetting of warnings
When the DIP switch has been set to "ON",
the cycling and dry-running warnings will
automatically be reset if they have been activated.
See section 8.2.3 Resetting of dry-running warning.
