PHP A-1 Instruction Manual / Operation and display
USER LEVEL 3 ACTIONS:
Cart. change MWE
After changing the softening
Cart. change MVE
cartridge resp. the desalination
cartridge the change must
be confirmed.
Start/stop
fast degassing Thus the remaining capacity will
be set anew due to the set water
hardness resp. water conductivity.
USER LEVEL 3 SETTINGS PRESSURE MAINTENANCE:
To set the desired working pressure
Working pressure
see Chapter 6 "commissioning"
- "Step 11".
Operating. mode
At double-pump systems (systems
pumps Duo and Maxi) you can choose the
following operating modes:
• "pump M1 only"
Pump M2 is deactivated
permanently (e.g. for
maintenance works).
• "pump M2 only"
Pump M1 is deactivated
permanently (e.g. for
maintenance works).
• "redundancy mode"
The actual priority pump starts
pressure-dependent. The
additional pump starts only in case
of an error of the priority pump.
• "staggered mode" (default setting
at systems Duo and maxi).
The actual priority pump starts
pressure-dependent. The
additional pump starts in case of
an error of the priority pump, also
it starts pressure-dependent.
• "parallel mode"
Priority pump and additional pump
always run at the same time.
Operating mode
Selection of the used level
level
measurement at devices with enabled
second level measurement L2:
• "automatic change"
Automatic change to the second
level measurement L2 in case of
identified electric faults at level
measurement L1 (at least one of
the error messages E12, E13,
E14, E15 must be released).

• "level L1 only"
Only L1 is used for level
measurement
• "level L2 only"
Only L2 is used for level
measurement
USER LEVEL 3 SETTINGS MAKEUP:
Operating mode
Selection of the operating mode of the
enabled EMCF-1 V makeup module
• "amount-controlled"
If the set available amount is used
(see max. amount), error message
E26 will be released and the
makeup will be disabled.
• "time-controlled"
The set max. amount is available
within the set period "period for
amount". If more than this amount
is used within this period, the error
message E26 will be released and
the makeup will be disabled.
Otherwise the entire amount "max.
amount" will be enabled for the
next period.
Max. amount Set the max. amount in litres.
Set the period of time for operating
Period for amount
mode "time-controlled".
Level: start makeup
Make-up starts below this level
