Introduction
Thank you for choosing the AS Control Plus an innovative control
system incorporating a microprocessor. lt will dramatically improve
the energy efficiency of overflow / infinity swimming pools and avoid
unnecessary energy losses. On our test Pool (50 m2at 30 °C water
temperature) in Switzerland we were able to demonstrate an energy
saving of more than 20‘000 kW (equivalent to 2‘000 litres of oil) in a
six-month period (May to October).

Pump switched off:
If the pump is switched off or there is an electricity cut, the
Besgo valve will be in economy mode (drain directly from the
pool). In this way the pool will not be emptied by mistake. The
water cannot be fed back into the overflow tank via jets and the
filter. That would lead to a loss of water, if the water level in the
collection tank were to rise so high that the water flowed over
the edge of the buffer tank.
As additional security we recommend the installation of a
non-return valve into the inlet jet system as well as the
incorporation of a forced start (5th probe) in the collection
tank.
Comments on the energy efficient control
(Overflow and economy mode)
The most original concept of the AS Control Plus is the tempera-
ture-dependent switching between overflow and economy (also
known as normal operation) modes of operation and the resultant
energy savings.
1. Overflow operation:
In the so-called overflow operation (normal operation) the water is
circulated via the overflow channel ➔overflow tank ➔pump
➔pool ➔overflow channel. The hydraulic operation is optimal
because the pool water is drained via the overflow. However, with
high water temperatures and low air temperatures there is a large
amount of heat loss (evaporation, convection). During operation,
with the pool covered open, the pool water has to be circulated
via the overflow.
2. Economy mode:
In so-called economy mode water is drained directly from the pool
(i.e. from one or more drains). Pool ➔pump ➔pool. Thus the
water no longer flows via the overflow. The heat loss is reduced
considerably. Economy mode is best suited to periods of cold
weather or during a pool heat-up period. During periods of use
the pool should always be run in overflow mode for reasons of
security and hydraulic efficiency.
Limits of liability:
We do not assume any liability for the layout or safety of the
drainage system. The correct layout of the drainage system is the
responsibility of the installation company. The local regulations
concerning the safety of drainage systems must be observed.
If there are no specific regulations we always recommend that
drains with hair-trap security be fitted. As well as installing at least
two drains with a distance of 1,5 m between them. The suction
speed of the drains should not exceed 1,2 m/s. The ideal position
for drains is where the bathers cannot come into contact with them.
CAUTION: incorrect drain installation can cause death.
Limits of liability:
We do not assume any liability for the cost of loss of water, which
is caused by the failure, and/or misuse of the AS Control Plus or
the Besgo valves.

Heating key:
Auto: heating operates according to the programmed filter time
Off: heating is switched off
On: if this light is lit the heating is operating. The set temperature
has not yet been reached.
Filter key:
Auto: filter operates according to the programmed filter time
Off: filter is switched off
On: filter operates permanently
ECO switch:
There are three options:
1. Auto operation:
In this position, as a function of air and water temperatures, it is deter
mined whether drainage will take place directly via the pool (economy
mode) or via the overflow channel. As soon as the pool cover is opened,
the system goes into overflow mode. (The limit switch must be connec-
ted to terminals 71/72)
2. Main drain operation (economy mode):
The Besgo valve is always in the economy mode and drainage is via the
main drain irrespective of temperature and whether the pool cover is
open or closed.
3. Overflow tank operation:
The pool is always drained via the overflow channel – irrespective of
temperature and whether the pool cover is open or closed.

By pressing the MODE key you enter the menu.
The additional functions are indicated in the menu with the ➔Symbol.
MENU LANGUAGE: (factory setting is German
Press the OK key and you can then select by means of the arrow key
between German, French, Italian, English and Spanish..
FILTER PUMP MENU
OVERLOAD PROTECTION: (factory setting is OFF)
Press the OK key and you are then in the overload protection menu
where you can first select if the overload protection is to be switched
on or off. If the OP is switched on, by pressing the OK key the motor
current will be measured, displayed and saved for the connected pump.
If you decide to connect a different pump to the AS Control Plus, you
will need to determine the current for the new pump. You can exit the
display of the current by pressing the MODE key. Once you have deter-
mined the current, you can select the tolerance level to determine the
percentage overload at which the overload protection is triggered and
the filter pump switches off (typically the tolerance is set to 15 %).
If the contact of the flow switch opens, the pump stops after a delay of
20 seconds.
FILTER TIMES (Factory settings: 08.00 to 09.00)
By pressing the OK key you can select up to five filter times per day, when the water will
be channelled via the overflow. This is necessary since the water level is only controlled in
the collection tank and not in the pool.
CAUTION: You must circulate the water via the overflow for at least 30 to 60 minutes per
day. Only in this way can you measure and control the water level (the measurement
takes place in the overflow tank).
Additionally, the correct water flow (via the overflow channel) will be re-established by
entering the times for the overflow operation, which will ensure proper circulation within
the pool. With public pools, we recommend switching to over-flow operation between
one and two hours before the pool is occupied in order to ensure the correct water flow.
CAUTION (Warranty exclusion)
Damage which is caused by too low a water level (e.g. burnt-out solar cover) will not be
covered by us.
CANCELING FILTER TIMES: by pressing the OK key, all filter times can be cancelled.
During this process you will be asked to confirm whether you really mean to cancel all
filter times. You confirm by pressing the OK key.
HEATING MENU:
SET VALUE: (factory setting 25 °C)
By pressing the OK key the set point of the water temperature can be
selected by means of the arrow keys between 1 °C and 40 °C.
Shortcut: Press the Filter button for 4 seconds to start a backwash
FROST PROTECTION: (factory setting OFF)
By pressing the OK key the frost protection can be selected as ON or OFF by means of
the arrow keys. In the ON position you can select by means of the OK key at which tem-
perature (-50 °C to +20 °C) the frost protection switches on the filter pump. The adjustable
hysteresis (temperature difference between ON and OFF) gives the switch-off signal.
Additionally a collective alarm can be interconnected. If you have a heating system connec-
ted you can select at which pool water temperature the heating should switch on and off.

02-2019 EN AS Control Plus 7
HYSTERIS (factory setting 0.5 °C)
By pressing the OK key the hysteresis can be adjusted between 0.1 °C and 5 °C by means of the
arrow keys. Hysteresis means the number of degrees Celsius, which separate the switching ON and
OFF.
FILTER DELAY STOP (factory setting 3 minutes)
By pressing the OK key the filter run-on time can be adjusted between 1 and 200 minutes by means
of the arrow keys. The run-on time can help to stop a build-up of heat in the system by ensuring that
the filter pump continues to run after the heating has been switched off. If a run-on time has been set
via terminals 24/25 and/or 31-33, this time will be added to the run-on time for the filter.
DELAY STOP TERMINAL 24/25 (factory setting 0 minutes)
By pressing the OK key the filter run-on time can be adjusted between 1 and 200 minutes by means
of the arrow keys.
DELAY STOP TERMINAL 31-33 (factory setting 0 minutes)
By pressing the OK key the filter run-on time can be adjusted between 1 and 200 minutes by means
of the arrow keys.
HEATING PRIORITY (factory setting OFF)
The heating can also be switched on outside the filter operation times. By pressing the OK key the
heating priority can be switched off or set to a temperature difference of between 1 °C and 10 °C for
heating priority.
BACKWASH: (factory setting Friday)
By pressing the OK key the backwash can be completely switched off or the day of the week changed
or an interval of 1 to 30 days between backwash cycles chosen by means of the arrow keys.
BACKWASH VIA: (factory setting overflow tank)
By pressing the OK key you can select, by means of the arrow keys, whether the backwash takes
place via the overflow tank or the main drain.
DELAY STOP VIA OVERFLOW (factory setting 30 minutes)
After every backwash there is a compulsory flow via the overflow channel. The time is adjustable
between 0 and 200 minutes.
START TIME (factory setting 10.00 am)
By pressing the OK key you can select the time at which the backwash starts.
DURATION: (factory setting 4 minutes)
By pressing the OK key you can select, by means of the arrow keys, the duration of the backwash
between 1 and 30 minutes.
PAUSE (factory setting 30 seconds)
By pressing the OK key you can select whether you want to pause between each individual step.
The duration of the pause can be set, by means of the arrow keys, to between 30 and 200 seconds.
RINSE (factory setting OFF)
Press OK. With the arrow buttons you can turn rinsing ON/OFF or select compressor. The duration of
the rinsing can be set between 1 and 200 seconds. If you choose the setpoint „compressor“ you can
connect a compressor instead of a backwash valve. It will turn on before and during the backwash
(Pause = Lead time). The compressor will be activated as well during overflow mode.
BACKWASH MENU
TEST BACKWASH
By pressing the OK key a backwash cycle can be started manually.
The progress of the backwash cycle can be observed on the display.
Shortcut: Press the Filter button for 4 seconds to start a backwash.

TOP-UP (factory setting 90 minutes)
By pressing the OK key you can select whether the top-up with fresh water should be time-controlled
or whether the top-up is switched ON or OFF. If the top-up is time-controlled, you can set the time
limit for the top-up between 1 and 999 minutes. If the time limit has been reached and the water level
has not reached its set height, there is a problem with the top-up system. The top-up switches off and
the override alarm is triggered.
BACKWASH WITH FORCED START (factory setting OFF)
Here you can select automatic backwash in the case of forced start. In this way you can avoid too
much water from draining away needlessly via the safety overflow. The water can then be used again
for another backwash. Backwash can also be useful when heavy rain causes the overflow channel to
be switched on, thus causing an unnecessary waste of energy. The delay time for the backwash can
be set between 1 and 200 minutes.
GENERAL ALARM: RUN-DRY PROTECTION (factory setting OFF)
By pressing the OK key you can select whether to trigger the general alarm in the case of a run-dry
situation. If you activated the general alarm, you can select a delay time of between 0 and 200 minu-
tes. When this time has expired, the general alarm is triggered and a warning text appears in the blue
display panel.
COLLECTVE ALARM: FORCED START
By pressing the OK key you can select whether to trigger the collective alarm in the case of a forced
start situation. If you activated the general alarm, you can select a delay time of between 0 and 200
minutes. When this time has expired, the general alarm is triggered and a warning text appears in the
blue display panel.
OVERFLOW TANK MENU:
MAIN DRAIN AT DRY RUN PROTECTION (Factory settings: OFF)
The «Besgo» valve switches to main drain to avoid stopping the filtration
pump because dry running (empty overflow tank).
By pressing the OK key you can select this function ON and OFF.
By pressing the OK key you can select whether overflow operation is triggered when a specific
ambient air temperature is reached or when a specific temperature difference between ambient
air and water temperatures is reached.
a) Set temperature: until the set temperature for air is reached, the system remains in economy
mode (no current to the Besgo valve - drained directly from the pool). Only when the set temperature
has been reached does the Besgo valve switch to overflow mode. Setting 5 °C to 40 °C. When solar
covers are being used we recommend the use of the set temperature. The set temperature should
be set no higher than 20 °C. At a temperature of 20 °C in the shade, there is considerable solar gain
from the cover which is stored up under the cover in economy mode. Temperatures under the cover
can reach as much as 50 °C and more. This heat accumulation must be dissipated via the overflow
channel.
b) Temperature difference: You can set a temperature difference of between +10 °C and -10 °C.
For example, if a temperature difference of +2 °C is set, then the Besgo valve switches to operation
via the main drain if the air temperature is 2 °C higher than the water temperature. If a temperature
difference of -2 °C is set, then the Besgo valve only switches if the air temperature is 2 °C lower than
the water temperature.
CAUTION: (liability exclusion)
Some pool manufacturers (polyester, liner) limit their warranty to use at temperatures of 30 to 35 °C.
Potential damage to such pools or their covers is not covered by us.

By pressing the OK key you can select a start time delay between 0 and 3600 seconds. The start
delay is always active if: the power supply connected, after a failure of the power supply, when the
filter pump starts. By means of the start delay the outputs for heating, regulation and forced start
are locked.
POOL TEMPERATURE CORRECTION: By pressing the OK key you can adjust by means of the arrow
keys the actual pool water temperature shown in the blue display by up to +10 °C to -10 °C. This fine
adjustment is useful when there is a difference between the measured and actual pool temperature
due to the positioning of the temperature probe.
AIR TEMPERATURE CORRECTION: By pressing the OK key you can adjust by means of the arrow
keys the actual air temperature shown in the blue display by up to +10 °C to -10 °C. This fine
adjustment is useful when there is a difference between the measured and actual pool temperature
due to the positioning of the temperature probe.

IMPORTANT INFORMATION:
Terminals 45/46. A manual switch ON/OFF-I can be connected to these two terminals.
By switching on the manual switch the filter pump is switched on and operation via
the overflow channel is initiated. It is advisable to mount this manual switch near the
pool.
Terminals 52/53. These terminals can be used in conjunction with an air-conditioning
unit. When the contacts are closed, circulation is via the main drain.
Terminals 71/72: These terminals can be connected with the swimming pool cover.
If these contacts are closed the ECO control (if set to AUTO) decides whether water
will be circulated via the main drain or the overflow buffer tank. The pre-set filter times
remain. The potential-free contact of the limit switch for the pool cover must be wired
as follows: pool cover on the pool = closed limit switch contact.
.
Priorities
The overflow filter time always has priority over other actions. This means
that when the unit is operating via the main drain (in economy mode) and the
overflow filter times are active, the controls switch to normal operation.
With the same objectives, the following priorities are active:
Im gleichen Sinn sind folgende Prioritäten vergeben:
> 1. Overflow filter time
> 2. Manual switch (terminals 45/46)
> 3. Unit switch (auto/ main drain/ overflow tank)
> 4. Cover limit switch (terminals 71/72)
> 5. Eco-programme (set temperature and differential temperature)
FROST MONITOR
The frost protection mode only allows the heating to start, if the filter pump started
over the air temperature.
Hysteresis
Example:
Set temperature 28 °C / hysteresis 1 °C / actual temperature 20 °C
In this example the heating will heat until 28 °C and then switch off. The heating will
only switch on again when the water temperature drops below 27 °C. In this way you
ensure that the temperature can only vary between 27 °C and 28 °C.
