Zoning control for 4 valves.

Features

AQ257 for zoning with zone valves with end switches
Auto test function to test zones at system start up. It allows for operator controlled testing of zones; includes pause/restart capability.
LED lights for visual diagnostic of zone operation.
Allows zoning with either "Normally Open" or "Normally Closed" zone valves.
Adjacent zoning panels can operate different zone equipment - one panel may control 4 pumps while another may control 4 zone valves.
Easily switch from zone valves to pumps with same zoning module - just flip one DIP switch. Ensure correct voltage is applied to all zone equipment on a panel (120 Vac for pumps, 24 Vac for valves)
R-C transformer and B-B data bus terminal connections (network communication) for easy expansion.
Zones can be set to energize a group pump via Aux Out dry contacts on main control panel (AQ250, AQ25A, AQ251, AQ252) or expansion control panel (AQ254).
Zone synchronization through Zone of Greatest Demand control.
38 VA Transformer with self resetting electronic fuse.
