Description for Honeywell AQ25042B

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

  • Controls up to 2 stages of heat from a single thermostat.
  • Use with AQ1000 2-wire communicating thermostats, or most dry contact digital thermostats.
  • Zoning Control for up to 4 zones as shipped; can be expanded to a total of 16 zones with AQ255 or AQ257 expansion zoning panels and up to 64 zones when used with AQ254 Add-A-Temp panels.
  • Line or low-voltage output for zoning equipment (pumps or valves).
  • Zone synchronization through Zone or Greatest Demand control.
  • Domestic hot water priority and priority override protection.
  • Boiler short cycling protection.
  • Boiler post purge.
  • Freeze protection.
  • Pump/valve exercise.
  • Boiler shock prevention from cold water returning to boiler.
  • Automated test feature for quick start-up and simplified troubleshooting.
  • Integral 38 VA transformer with self-resetting electronic fuse.

        Comments about Aquatrol Boiler Control Panel for 4 Zones or 2 Wire Valves:

        Works fine but the thing they don't tell you is that is takes 20 mins to start up before it will register a heat demand and turn on the boiler. I almost sent it back, spent ages trying to figure out why it wasn't working. Then one time I happened to leave it switched on and when I came back later bingo! it had started working.
