Hardie HR-6100 All Zones Run on Water Turn-On: Valve Bleed Screws Left Open

HR-6100: water on → all 5 zones run before controller powered. Winterizer likely left manual bleed screws open on valves.

Fix

1. Find valve boxes.
2. On each valve, locate black plastic bleed screw on top.
3. Turn clockwise to close (snug, not forced).
4. Also check solenoids are snug (not backed off).

Why This Happens

Winterization: open bleed screws to drain valves. Spring: forget to close them. Water pressure → valves open manually.

Reset Not Needed

Controller is fine. Valves are mechanically held open. Close bleed screws, system returns to normal.

Check this first—costs $0, takes 5 minutes.
