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

. 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).

. 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.
