There are two LEDs under the top button/rocker switch on the configurable control
panel. These remain permanently on so that the unit can be located more easily in the
dark.
The yellow “Service” LED is fitted under the last button/rocker switch on the configura-
ble panel and indicates the status of the room unit by means of different flashing pat-
terns (see the RXT10 user manual, CM110669).
Disposal
The devices are classified as waste electronic equipment in terms of the European Direc-
tive 2012/19/EU
(WEEE) and should not be disposed of as unsorted municipal waste.
The relevant national legal rules are to be adhered to.
Regarding disposal, use the systems setup for collecting electronic waste.
Observe all local and applicable laws.
Engineering notes
The flexible room unit is connected to the LONWORKS® bus by a two-wire twisted cable
and receives its power via the bus cable. This cable must be connected to a central bus
power supply in accordance with LPT-10 (see the Installation guide, CA110334).
For mounting, a standard recessed conduit box or an aperture of the equivalent size is
required.
Mounting notes
• The room unit must be mounted on a recessed conduit box
• Mount on a flat surface with a maximum offset of 1 mm
• The base plate should be fixed with screws, max. diameter 3.5 mm
• Do not mount in recesses, shelves, behind curtains or doors, or above or near heat
sources.
• Avoid exposure to direct sunlight or draughts.
• The electrical wiring conduit must be sealed where it joins the room unit, to prevent
the occurrence of draughts in the conduit which could affect the sensor.
