All Zones Activate After Manual Valve Operation: Return Valves to 'Off' Position

Turned Off Control Valves, Then Opened Manually; Now All 4 Zones Run Together from Timer

Valves must be in the "OFF" position at the solenoid/bleed screw for the timer to control them. If any valve is left manually open, the timer will energize all zones simultaneously.

Go to each valve box.
Turn the solenoid or bleed screw to the fully OFF position (don’t over‑tighten).
Test the timer again.
