Controller mode - constant pressure control:
In this mode the Hydrovar- Watercooled is controlling to a constant output pressure
independent from the required flow rate, but limited to the maximum performances of the
pump. The integrated low water protection shuts off the pump when the output pressure
during operating of the pump is below 25% of the stored required pressure for longer than
20 seconds. In that case the controller will shut off the pump and will show Error code 26
“Lack of water”. This kind of failure will be reset automatically for 3 times with a delay of
another 20 seconds. After the 3
rd
try, the Hydrovar- Watercooled has to be reset by removing
the power supply.
Adjustment of the required pressure:
Press (+) and (-) together for 3 seconds till all LEDs are illuminated.
The required pressure setting is now active and will be indicated by shining of LED 1 and 6.
LEDs 3 and 4 in the centre of the LED bar are blinking alternately.
Required pressure can be changed
Press (+) (=increase) or (-) (=decrease) to set the required pressure. The changing of the
operating pressure of the pump is shown on the manometer.
If no button is pressed for more than 10 seconds, the new setting will be saved automatically.
