Controller Status LED
The LED changes colour when the controller enters three (3) different states as follows.
Water On. Green LED remains illuminated when water is being supplied/valve is open (energised).
Fault. Amber LED remains illuminated when the rope fault is detected. Water supply will remain ON, BMS
terminal will switch over. Amber LED will turn Off and BMS terminal will switch back when rope fault has
been rectified. This feature is available only with 4 wire leak rope.
Alarm. Illuminated when water leak is detected. Water supply is Off (valve deenergised) until alarm
condition has been investigated, rectified, and reset. BMS and Strobe terminals will switch over.

There is a switch on the circuit board labelled [AUTO RESET] which can be used to automatically reset Alarm
condition after water leak has been rectified (should only be used in conjunction with WLDZ2 or WLDZ4 panel).
Controller requires manual reset after Alarm (Default).
