General notes
Introduction
These operating instructions describe the installation, operation and programming of the Softmaster MMP compact
controller. We recommend that, while familiarising yourself with the operation of the instrument aided by these
operating instructions, you have immediate access to the operable controller in order to perform the described
functions and combinations. As certain functions are interrelated, it is advisable to follow the instructions in the given
order.
Should problems or questions arise while operating the controller which are not described in these operating
instructions and/or cannot be solved, our customer service is always at your disposal.
Try to identify the problem as accurately as possible and record the actions and conditions under which it occurred.
This will enable us to offer you swift effective assistance.
Handling notes
Quick, repeated switching on/off of the controller should be avoided. Wait at least 5 seconds before switching'on'or 'off' at
the main switch.
Onlyoperate the controller in compliance with the ambient conditions (e.g. temperature, moisture) stated inthe Technical
Data. Always protect the controller against moisture.
It should never come into contact with condensation or splash water.
The warranty shall not apply if the controller is tampered with, altered, modified or repaired contrary to the instructions
described in this manual.
Before dismantling a defect controller, always write down the description of the error (failure effect).
The repair of a defective controller (irrespective of the warranty period) is only possible when the controller is dismantled
and returned to us with a description of the error.
The maximum electrical load capacityof the relayoutputs and the total power rating of theplant should never beexceeded.
The controller should only be used for its specified intended purpose.
Safety instructions
Always adhere to the following safety instructions:
The controller must be installed and operated in compliance with relevant standards (e.g. DIN, VDE, UVV) or in
accordance with regulations laid down by the respective country.
Some functions (e.g. manual filter change) allow direct manipulation of the plant (valves, pumps, etc.) without locking
or monitoring. These functions should only to be used by fully qualified personnel.
If you observe malfunctioning of the controller, switch it off immediately and inform the service personnel.
Do not attempt to repair the controller yourself (loss of warranty rights); instead always contact authorised service
personnel. This is the only way to ensure reliable and safe operation of the plant.
After a protective circuit (fuse, motor protection switch) has been triggered, attempt to eliminate the cause of
malfunctioning (e.g. clean the pump) before reactivating the protective circuit. Frequent triggering is always due to an
error which, in certain circumstances, may also cause damage to the controller.
Non-adherence to these instructions can damage the controller as well as the plant and may result in a loss of warranty
rights.
Installation and commissioning
Installation and commissioning should only be carried out by authorised technicians!
The connecting cables to the sensors should be kept as short as possible and clear of power cables. Close proximity
to strong electromagnetic radiators can lead to deviations of the display; in this case, separate interference
suppression measures should be carried out.
After installation, program the instrument with the plant-specific features and data (e.g. switch functions, conductivity
limit values, etc.). The data is permanently stored (also during power failure).

In addition to the displayed error messages, the red LED ‟Alarm” lights up or flashes.
Alternate display of all error messages and operating displays.
Each occurred error is stored in the error history.
Error message ‟Power failure”
Message after each switching on, ‟power failure”. Check the time and, if
necessary, set the time.
After switching on or after voltage recovery, the controller starts with the last active status. Current regeneration is
continued.
Check the plant for possible negative results due to the power failure (e.g. exhaustion due to excessive washing in the
regeneration stage ‟wash out”).
All stored values remain stored even during a power failure.
Confirm the fault display via the key.
Error message ‟Plant override”
Regeneration triggered via a contact at the START input or via too high
consumption while a filter is still being regenerated.
In multi-filter plants it can occur that a filter is in regeneration and a second filter is also waiting to be regenerated. This
status can occur if the soft water consumption is very high, e.g. when filling a swimming pool. If this scenario occurs,
the plant will only provide raw water to the consumers. If only soft water should be provided, the soft water supply to the
consumers has to be closed.
Wait until the current filter regeneration has finished and then open the soft water supply to the consumers. The
controller will always automatically complete regeneration of this filter.
Find and eliminate the fault and confirm the fault display via the key.
If regeneration is really necessary again (triggered via consumption measurement), regeneration will occur at the end
of the current regeneration.
If you have programmed a minimum regeneration interval, regeneration will be started after this period has expired.
With triggering via a contact at the START input, you have to start regeneration manually via the key.
Error message ‟Minimum regeneration interval not achieved”
Regeneration triggering via a contact at the START input or via excess soft
water. The required temporal interval to the previous regeneration has not
been observed.
Confirm the fault display via the key.
Regeneration requested via the water consumption is executed after the programmed period.
Regeneration triggering via the START contact is ignored. Check the plant and trigger a required regeneration
manually. The error message is subsequently deleted.

In addition to the error message, the yellow warning light ‟Low chemicals” lights up.
Confirm the fault display via the key. The message remains until the regeneration meter has been deleted.
Delete the regeneration meter in the SERVICE menu under ‟Reg. meter”.
Error message ‟Low chemicals”
The chemical tank is empty.
The EMPTY signal is present at the contact input ‟LL” and the input is
programmed as the ‟Low chemicals” contact.
In addition to the error message, the yellow warning light ‟Low chemicals” lights up.
Confirm the fault display via the key.
Check the chemical tank and the desalination valve or the automatic refilling of the proportion tank. The error display is
only deleted after the fault has been eliminated.
Error message ‟Regeneration stopped”
If the program has been stopped via an external switch (STOP input) prior to
or during regeneration and if you have programmed the alarm message for the
STOP input, the display "Reg. STOP/Hold" will appear as an error message.
Confirm the fault display via the key.
The display will be deleted as soon as the switch re-opens and the program continues.

Description of the relay outputs
Filter 1 / Filter 2 Pilot distributor or central control valves 1 and 2
Connect the regeneration valves (central control valves) or pilot distributors which are controlled via an electrical change-
over switch or impulse switch control at these relay outputs (terminal 5, 6, 7, 8 and 5‘, 6‘, 7‘, 8‘).
Change-over contact: For versions with a change-over switch the output changes after each regeneration stage.
Impulse: For versions with an impulse switch control the output switches for 40 seconds (terminal 7 or 7').
The idle position of the relay is the same for de-energized controllers and in the operating position of the filter: Contact at
terminal 6 or 6'.
The control version can be set under the menu item
"M" BASIC PROGRAM Valve type
Sync Synchronous contact / Regeneration message
After power failure (e.g. during regeneration) or with faults, it is usually necessary to synchronise the valves or pilot
distributors with the controller. For regeneration valves / pilot distributors with a change-over controller and an uneven
number of (electrical) regeneration positions it is necessary to connect these to the synchronouscontact.This ensures that
the regeneration valve / the pilot distributor returns to the operating position after regeneration. The connection occurs at
terminal Sync –8 or 8’.
The connection ‟Sync” can be used to externally display the program course (regeneration) orto control arelayor solenoid
valve during regeneration.
BV1 / BV2 Operating valves Filter 1 and 2
The operating valves of the filters have to be designed as normally closed.
AL/PR Fault message output / additional program (terminal “C NC NO”)
The volt-free output AL/PR can be used for various functions:
as additional program PR
The additional program is used for controlling an additional valve prior to, during or after regeneration with
programmable on-time. If the output AL/PR has been switched, the LED "PR" will light up.
Program the function under the menu item (see basic programming ‟Aux Prog."):
"M" BASIC PROGRAM Aux Prog.
as fault message output ("Alarm")
During trouble-free operation the contact between the terminals C - NO is closed and the one between terminals C - NC is
open. In case of power failure or a fault, the contact between the terminals C - NC is closed and the one between terminals
C - NO is open.
The controller monitors a whole range of plant statuses. The fault messageoutput remains active(terminals C - NOclosed)
until the fault has been eliminated and confirmed.
The red LED "Error message" and the text on the display indicate a fault.
The fault message signal at the fault message output is deleted by confirming the fault via the key.
The fault display can only be deleted if the fault has been eliminated.
(NO = Normally open, NC = Normally closed; Normally means: switch position is current-free)
The following faults activate the fault message output and are displayed if the softening plantor valves/pilot distributor have
been equipped with the respective contacts:
The following statuses always trigger a fault message:
Power failure
Plant overrun (regeneration start while a filter is still being regenerated)
Occurring error messages depending on the programming:

Operating modes (plant type)
The Softmaster®MMP 1 compact controller can control the following softening plants:
Single-filter plant
Only one filter is in operation. Soft water is not available during regeneration.
Programming: ‟Single-filter ”
Two-filter operation
One filter is in operation and the other filter is in the reserve/standby position or is being
regenerated. Soft water is usually always available.
Programming: ‟2-F.change ”
Electrical control of the regeneration valves
You can use control valves or pilot distributors with up to 8 stages / positions with
impulse or change-over control.
Examples for 4-stage valves/pilot distributors:
as change-over contact
For versions with a change-over switch the output
changes after each regeneration stage. With an odd
number of the mechanical positions, operating position
reset has to occur via the synchronous contact (operating
switch).
as impulse
For versions with an impulse switch control, the output
switches for 40 seconds at the beginning of each stage

Hardness unit
The raw water hardness can be entered and displayed in various units:
German hardness = dH
French hardness = f (1.79 = 1° dH)
ppm as CaCO3= ppmCaCO3(17.9 ppmCaCO3, 1° dH)
The exchanger capacity has to be entered (in the next menu item) according to
the unit.
Exchanger capacity
The filter capacity in a m³ available soft water quantity is calculated by the controller.
You enter the exchanger capacity of a filter in m³xdH, m3x°f or gCaCO3and the
current raw water hardness (in the ‟Service” menu).
Calculation of the filter capacity
The filter capacity (also known as the filter performance), i.e. the available soft water quantity, is calculated on the
basis of the entered raw water hardness.
"M" Service Hardness raw water Input: 016°dH (example)
The filter capacity remains constant: Exchanger capacity
Filter performance = (in m3)
Raw water hardness
The total filter capacity (available soft water quantity after regeneration) can be requested in the service menu:
"M" Service Filter capacity
The remaining residual filter capacity or residual soft water quantity is displayed in the operating display.
Regeneration
Regeneration start
The regeneration of an exhausted filter can be started via various triggering criteria:
- Manually by pressing the key (press the key for 5 seconds)
- After removal of the set soft water quantity (filter capacity)
- After end of the set daily interval for the programmed time
- Via start impulse from the water hardness measuring instrument (Testomat)
Manual regeneration
A filter change occurs with a manual regeneration start. The filter in operation is regenerated and the filter in the reserve /
standby position is put into operation (only for double-filter operation).
Quantity-dependent regeneration
In most cases it is recommended to record the removed soft water quantityand to regenerate the filter whenthe calculated
filter capacity has been achieved. The filter capacity is calculated by the controller using the programmed exchanger
capacity(m3x °dH) and the raw water hardness. The quantity recording occurs via a water meter in the filter / plant output.
If you wish to prevent regeneration at an inappropriate time during operation, program regeneration delay. Required
regeneration is not started until the set time, e.g. 8 pm (see "Regeneration delay"), has been reached.
During change-over mode, the instrument immediately switches to the filter in the reserve position and regenerationof the
exhausted filter is carried out at the set time.
Delayed regeneration can result in the overrun of the filter. This can be prevented by selecting early regeneration
triggering (Reg. start for x% filter residual capacity).
Time-dependent regeneration
If the plant is to be regenerated in a time-controlled manner, program the daily interval and the time of regeneration
(regeneration delay = ON).

Quality-controlled regeneration
With the internal control function combined with a water hardness measuring instrument (e.g. Testomat 2000®/ ECO) it is
possible to install a convenient and reliable plant. The water hardness measuring instrument monitors the soft water
hardness and sends a start signal to the controller to trigger regeneration once the set limit value has been reached.
By combining the various control possibilities you can ensure the largest possible operational reliability.
Stopping or delaying the regeneration
You can cancel a current regeneration manually at any time via the key. A regeneration can be delayed or a current
regeneration stopped via a contact at the STOP input.
Regeneration stages
You can program up to 8 regeneration stages. The minimum time per stageis 0or 1minute (1 minute: operatingtime of the
valve / pilot distributor), the maximum time is 99 minutes (250 minutes for stage 1).
Regeneration delay
If a triggered regeneration (e.g. by reaching the filter capacity, time interval or measured
hardness irruption) should be carried out at a later date or only within a time window,
program regeneration delay ON and the corresponding times.
Regeneration is then only started at the set start time ‟Reg. at: ”, e.g. 8 p.m.. Enter the
latest time for the regeneration start under ‟Reg. to: ”, e.g. 6 a.m..
This prevents regeneration from being carried out at an inappropriate time during
operation.
During change-over mode, the instrument immediately switches to the filter in the
reserve position and regeneration of the exhausted filter is carried out at the set time.
For single-filter plants it is possible to specify whether the operating valve should remain open until regeneration or be
closed immediately: ‟SV on (1-F) ” = operating valve is only closed at regeneration start.
Note
Delayed regeneration can result in the overrun of the filter. This can be prevented by selecting early regeneration
triggering (Reg. start for x% residual filter capacity).
Example for double filter:
Early regeneration triggering
Select this function for single-filter plants to ensure a certain soft water consumption for
the next day. If regeneration should not be started immediately after the set residual
filter capacity has been reached, please additionally program ”Regeneration delay” with
the desired time for regeneration start. This prevents regeneration from being carried
out at an inappropriate time during operation.
A further application possibility arises when combining "Regeneration prior to commissioning" for double-filter plants.
It is possible to set values between 0 and 50% of soft water reserve for early regeneration triggering.
(Default setting is 0% = no early regeneration triggering)

Regeneration interval
To prevent improper bacterial contamination of the resin bed during longer downtimes,
regeneration can be carried out at fixed daily intervals.
The regeneration interval (0 - 99 days) complies with the operational conditions and
national regulations for the drinking water supply (e.g. DVGW, DIN, etc.).
If regeneration should be carried out at a certain time, please additionally program
‟Regeneration delay” with the desired time for regeneration start.
Without regeneration delay the filter will be regenerated at the same time as the last regeneration.
The interval restarts after each completed regeneration.
In how many days the next interval regeneration will be carried out can be requested in the menu under
"M" Service Reg. Info Interv. days
On the day of the interval triggering of a regeneration the control lamp "REG” of the corresponding filter starts flashing
at midnight.
Regeneration prior to operation
Select this triggering type for double-filter plants where bacterial contamination problems can occur due to longer
downtimes of the filter in reserve.
To ensure that soft water is still available during the regeneration time, regenerationshould
be triggered early enough via "early regeneration triggering" so that soft water can still be
removed for approx. 2 hours.
Notes
It is not possible to combine this operating mode with the additional program prior to regeneration with immediate filter
change.
The manual service functions ‟Regeneration of the reserve filter” and ‟Filter change without regeneration” are also not
possible in this operating mode.
Minimum regeneration interval
If the softening plant is equipped with a desalination tank for chemical storage, the interval
between two regenerations has to be at least 4 hours to ensure sufficient chemical
concentration. Otherwise regeneration is insufficient and the plant is soon ‟overrun”.
If regeneration can be triggered by an analysis instrument (e.g. Testomat) due to hardness irruption, it is possible to
prevent frequent regenerating due to early triggering (e.g. due to hardness increase caused by counter ion effect, or
insufficient wash out of the filter, or possible malfunctioning of the measuring instrument) by selecting a minimum
regeneration interval.
If regeneration triggering (e.g. by reaching the max. removal quantity or externally via an analysis instrument) occurs
within this time, the error message ‟Min. reg. interval” is displayed and the alarm relay switches. Regeneration has to
be triggered manually.
Regeneration stages
Enter the number of regeneration stages (without operating position!) and the time of
the individual stages according to the used central control valves or pilot distributors.
You can program up to 8 regeneration stages / positions.
Choose the time for stage 1: 1 - 250 minutes, stage 2: 1 - 99 minutes,
stage 3: 1 - 99 minutes and the other stages: 0 - 99 minutes.

Output PR switches prior to regeneration
The output switches when regeneration is requested. If the signal duration of the additional program is expired, the
filter is changed or the operating valve is closed and the regeneration program starts.
Start stage: 0
If regeneration is requested:
the operating valve should close immediately for a single-filter plant or
the operating valves should switch over immediately for double-filter plant
then program „SV off (only 0)“.
Not possible with regeneration prior to commissioning!
Output PR switches during regeneration
The output switches at the start of an entered regeneration stage.
Start stage: 1 … 8
At the start of the entered regeneration stage 1 to 8, cannot be more than the number of reg. stages.
Output PR switches after regeneration
The output switches after the last regeneration stage is completed.

After completion of the last regeneration stage, cannot be more than the number of reg. stages + 1.
Program for how long the output PR is to be switched under „Duration“. The range is 0 to 999 minutes.
0 means, no additional program is used.
Water meter
The water meter is used for recording the used soft water quantity. The memory of the
water meter is deleted after each regeneration.

Function START input
If regeneration should be triggered quality-dependently, a water hardness measuring
instrument has to monitor the soft water hardness. If the set limit value has been
reached, the measuring instrument sends a start signal to the controller for triggering
regeneration.
With two-filter plants a filter change (only serial or double-filter operation) occurs and
regeneration is started according to the programming (e.g. regeneration delay).
"M" Basic program Funct. Start
Function STOP input
During regeneration it may be necessary to interrupt the process externally via a switch
(e.g. pressure switch in the input). A current regeneration can be stopped via a contact at
the STOP input or a pending regeneration can be delayed.
Function PROG input
The additional program can be externally started with this input.
"M" Basic program Funct. Prog
Chemical tank monitoring (LL input)
The input ‟LL" has been designed as level transmitter input for the "Low chemicals" alarm
or ‟EMPTY” level.
Program the desired effect of the contact, test time (delay) and alarm function. If you
monitor the desalination tank for low chemicals, the input is queried at regeneration
start. If the input is active = ‟Low chemicals” alarm, no regeneration is triggered. You
have to trigger regeneration manually and confirm the error message.
If the input ”Delay” is active after the test time in case of automatic filling of the chemical tank (also see additional
program PR), the output ”PR” switches. With simultaneous ‟Low chemicals” monitoring a ”Low chemicals” alarm
message (e.g. the tank is still EMPTY although the fill valve is open) occurs after the test time of the input.
