Overview
AQ255 AQUATROl expansion zoning panels from Resideo work with AQ2000 boiler control panels and AQ1000 communicating thermostats to control up to four space heating zones, up to 16 zones with additional panels.
Features
- Features AQ255 for zoning with pumps or zone valves without end switches
- Auto test function tests zones at system start up and allows for operator controlled testing of zones
- LED lights offer visual diagnostics of zone operation
- Adjacent zoning panels can operate different zone equipment
- Easily switch from zone valves to pumps with same zoning module
- R-C transformer and B-B data bus terminal connections (network communication) for easy expansion
- Zones can energize a group pump via Aux Out dry contacts
- Zone synchronization through Zone of Greatest Demand control
