Replacement Modules/Enclosures
Although AQ controls are very robust and designed to Honeywell's demanding standards of quality,
we know that sometimes things go wrong on the job site and a component gets damaged. That's
the beauty of the AQ2000 panel design – All modules pop off their Din rail, low voltage terminal
strips can be separated from the module without rewiring, and a replacement module can be in
place in just a couple of minutes!
