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 b10 °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
