Technical Support Line 01733 405 111 (opt. 3)

» Rain Mode (Normal Mode): System will use rainwater within the home. If rainwater is not available in the underground storage tank, the system will automatically register and switch over to mains water.

» Mains Water Mode: Press during a dry period or hose pipe ban to run internal appliances on mains water and conserve rainwater for garden use.

» Holiday Mode: If leaving the home for an prolonged period of time (over 1 week) press the holiday button to empty the header tank and refill with treated mains water. This prevents water quality issues.

When the system is used again it will automatically revert back to Rain mode. It may be sensible to flush each toilet twice to leave treated water in the cistern and bowl.

» Refresh Function: If no activity is registered within 3 days, the system will automatically refresh the water within the header tank. The system will drain the header tank back to the underground tank, and refill the header tank with fresh rainwater. This guarantees high quality water with no risk of discolouration or smells. Although the system refreshes automatically, the user can press the button to refresh the system at any point.

Problem Probable cause Remedy

Flashing red spanner light during initial switch on

Both float switches in low position

Part fill the header tank (as per point 8) Check Cat 5 connection is secure.

Flashing red spanner during commissioning

Wiring fault Check Cat 5 connection is secure, the wire provided with the system and has not been cut at any point.

Solid red spanner light during commissioning

Filling fault Check Rainwater and mains water are available to the system, repeat process 9 to remove airlocks from the system. Clear solenoid valves (contact supplier).

Mains water or refresh solenoid constantly open

Solenoid blocked open Clear the solenoid valve (contact supplier).

Mains filling light showing during normal mode

Rainwater tank empty or pump not functioning

Check the rainwater level in the underground tank. If the level is high refer to the pump guide.

Mains filling light showing despite rainwater working and filling first

Slow fill causing commissioning time-out

Check/clean the rain solenoid (contact supplier) recommission the system(refer to point 11).

No lights on the circuit board No power reaching PCB Check the power to the control unit, contact the supplier for further advice if problem persists.

Toilets not filling or the system is air locked

Water supply is less than demand

Check plumbing for obstructions, remove booster pumps, REMOVE GARDEN TAPS DIRECT FROM HEADER TANK, repeat.

Header tank overflow to waste Rain or Mains Solenoid blocked open

Clear the solenoid (contact supplier).

Power cut in the home Pump & control unit not functioning

Use the quarter turn valve (H) to bypass the system with mains water.

Poor rainwater flow into the header tank

Rain filter blocked Check the filter on the rain feed valve (I) and remove any dirt (turn off the pump first). Repeat after a week.
