The AQ250 family of AQUATROL Boiler Controls provides simplified, energy-efficient control of single temperature, residential hydronic heating systems. The AQ250 easily converts a single zone heating system into a room-by-room comfort control system, or upgrades a basic, relay-logic zoning system to intelligent Zone of Greatest Demand control for increased energy efficiency with reduced boiler cycling. AQ250 boiler controls can ensure ample supply of hot water for both space heating and priority generation of domestic hot water for bathing, dishes and laundry.

Features

• Factory configured for control of up to four zones plus domestic hot water.
• Expandable up to 16 zones with expansion zoning modules (sold separately).
• Single stage boiler control synchronized to zone-of-greatest-demand.

Note: Honeywell AQ Zone Panels require the Honeywell AQ1000TN2 for the system thermostat, and will not work with standard thermostats.
