Legacy Flow Error
Legacy Flow Error
The system isn’t receiving enough water flow.
Common causes:
Water is off or flow is too low
Flow meter is misconfigured in System Setup
Flow meter wiring is incorrect
Check that water is on and supplying enough flow. If using a flow meter, confirm it’s set up correctly and wired to Flo1 (Controller 2) or S1 (Controller 3), along with Common (C).
