AQ25542B Aquatrol Zoning Panel for 4 pumps
Part No. AQ25542B
Our Price: $113.00
The AQ255 and AQ257 family of AQUATROL Expansion Zoning panels work with AQ2000 Boiler Control Panels and AQ1000 Communicating Thermostats to control up to 4 space heating zones (or 8, for the AQ2558P2X Panel). Can be combined with additional expansion zoning panels and an AQ2000 control panel for a total of 16 space heating zones.
Features
Specifications
• AQ255 for zoning with pumps or zone valves without 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.
