Operations manual AQUASTOP

Error messages

8.1 Temperature sensor failure :

No signal on the temperature sensor entrance

=> Check the sensor connector

=> Check the electrical wiring

(might be damaged)

8.2 Flow meter failure :

Wrong signal on the flow sensor entrance

=> Purge the flexible hosing (air bubbles might

cause an irritation of the sensor)

=> Check the flowmeter for contamination

=> Check the flow (flow > 100l/h situated

out of the range of the flowmeter)
