New Hunter Pro-C Installed but No Zones Run: Check for Master Valve and Wiring Continuity

Old Timer Failed; Pro‑C Installed; Water On, Wiring Checked, Still No Zones

Does the system have a rain sensor or master valve? (Master valve wire on old timer’s "MV" or "PS" terminal?)
Any power surges/outages recently?
Photo of new controller wiring would help.

The red wire on the new controller suggests a master valve/pump start is present—start troubleshooting there.
