3 876 s RXL Room controller RXL39.1 Communicating room controller for fan-coil applications FC-13 The RXL39.1/FC-13 room controller is used for temperature control in individual rooms.
Use The RXL39.1 room controller is optimized for control of fan-coil systems in individual rooms. The function of each controller is determined by the application software. The controllers are delivered with a fixed set of applications. The relevant application is selected and activated during commissioning using one of the following tools: • "HandyTool" (the QAX34.
Technical design The RXL39.1 controller consists of a housing base, a housing cover and the printed circuit board with connection terminals. The controller also has a tool socket, a service LED and a programming button.
Terminal cover Terminal covers (RXZ30.1) are available as an option, to protect the connection terminals from physical contact and dirt. The service LED remains visible when the terminal covers are in place, and the programming button can be operated with a pointed implement. The cable is connected to the room controller by breaking out the perforated cable entry guide.
Communication The RXL39.
Disposal The device is classified as waste electronic equipment in terms of the European Directive 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.

Mounting The room controllers can be mounted in any orientation, and fixed as follows: 80060 80061 Rail mounting The housing base is designed for snapmounting on DIN rails, type EN5002235x7.5 (can be released with a screwdriver) Surface mounting There are four drill holes for screwmounting (see “Dimensions” for drilling template). The housing base is fitted with raised supports. When mounting note the following: • The controller should not be freely accessible after mounting.
