When winterizing your irrigation system, here’s what you need to do:
Open the Lumo valves manually by pressing and holding the control button on the valve for 5 seconds until the LED flashes (Lumo valves must be in the open position when lines are being purged)
Purge lines per your normal protocol
Once drained, close the Lumo valves by repeating Step 1 (alternatively, you may leave the valve open in manual mode, and it will auto-close 6 hours after it was initially opened, per its programming)
Lumo valves need not be kept in an open state nor powered off for the winter. If you have any questions, please contact Lumo Support.
