Richdel 446 Wiring Error Causes All Zones to Activate Simultaneously

All Zones Run Together; Wires on Terminals 4, 5 and Pump

Correct wiring:

• Common wire (white) → Controller "C" terminal → daisy‑chains to one solenoid lead on every valve.
• Hot wires → Each valve’s other solenoid lead → Controller terminals 1, 2, 3… (one per zone).
• Pump wire → Controller "MV" or "PS" terminal (if pump/master valve used).

Crossed wires at the controller or valve boxes cause simultaneous activation. Verify each connection.
