Fault Mode - Pentair Onga WaterSwitch WS1500200 Owner's Manual

Fault Mode

WaterSwitch has a mechanism to prevent the pump from running with no water.
If the level sensor detects water in the tank, but there is a blockage or partial blockage
somewhere in the system the following process will occur:
1. If WaterSwitch is supplying water and also senses water in the tank, it will activate
the pump to supply rain water.
2. If no rain water is delivered from the tank within 30 seconds, WaterSwitch will
switch to supplying mains water.
3. After 6 seconds if no rainwater has passed through the system, waterswitch will
divert to mains water.
4. If no water is delivered from the tank it will repeat step 2 and step 3 four times.
If there is still no water delivered, WaterSwitch will divert to 'loss of prime' mode.
5. The LED on the WaterSwitch will flash red to warn that abnormal conditions exist.
It also locks out the pump from further operation to protect the pump from dry
running, and to ensure that the house has continuous mains water supply.

General Operation
Your WaterSwitch operates entirely automatically without intervention. If electrical
supply is cut in your neighbourhood, WaterSwitch will automatically revert to
mains supply water, as there is no power to drive the pump. When power resumes,
WaterSwitch will continue to operate normally.
If town supply water is shut off in your area, WaterSwitch might not be able to detect
water demand in the household (e.g. if the toilet cistern needs refilling). By pressing
the manual override button, you can override normal control and start the pump to
supply water out of the rain water tank.
