What it is

The Honeywell ACS90 is a connection cable for a window open switch within a Honeywell evohome system. It links the window open switch to the evohome control arrangement so the heating can be held back when a window is opened. It is a Honeywell accessory supplied as a single cable.

Before you order

  • Confirm the installation uses Honeywell evohome controls.
  • Check that a window open switch is being wired into the system, as this cable is intended for that connection.
  • Confirm the existing wiring route and cable length available on site before ordering.
  • Keep the part number ACS90 to hand when checking against the existing installation.
