Description

RF-L UN-ST IP53 und RF-L LED-ST IP53 

are radio dimmers for the WS1 and

WS1000 Color or Style, WS1000 Connect controls and for radio control system So-
lexa II. A halogen or fluorescent light is connected to the 

RF-L UN-ST

. The 

RF-L

LED-ST

 is provided for LED lights. The radio dimmer allows dimming in 1% incre-

ments. 
A light connected to the radio dimmer can also be operated directly using the remo-
te control Remo 8/pro via the button interface RF-B2-UP or the solar radio button
Corlo P RF (without an additional control unit).

Functions:

Universal dimmer with automatic load recognition (phase angle control/
phase sector control)

RF-L UN-ST 

for hight-voltage/low-voltage halogen lamps in combination 

with dimmable power supplies and for energy saving lamps,
load max. 300 W

*These 

Radio dimmer RF-L UN-ST IP53 and RF-L LED-ST IP53

 should be in-

stalled in a protected area despite a high degree of protection because water can en-
ter in via the connectors. Please observe the instructions in Chapter 

Connection

.

The product conforms with the provisions of EU directives.

Installation and start-up

Installation, testing, operational start-up and troubleshooting should 
only be performed by an authorised electrician.

DANGER!
Risk to life from live voltage (mains voltage)! 

There are unprotected live components inside the device.

• Inspect the device for damage before installation. Only put undamaged 
devices into operation. 

• Comply with the locally applicable directives, regulations and provisions for 
electrical installation. 
• Immediately take the device or system out of service and secure it against 
unintentional switch-on if risk-free operation is no longer guaranteed.

Use the device exclusively for building automation and observe the operating inst-
ructions. Improper use, modifications to the device or failure to observe the opera-
ting instructions will invalidate any warranty or guarantee claims.
Operate the device only as a fixed-site installation, i.e. only in assembled condition
and after conclusion of all installation and operational start-up tasks, and only in the
surroundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may
occur after publication of these operating instructions.

2.1. Notes on wireless equipment

When planning facilities with devices that communicate via radio, adequate radio
reception must be guaranteed.  The range of wireless control will be limited by legal
regulation and structural circumstances. Avoid sources of interference and obstac-
les between receiver and transmitter, that could disturb the wireless communicati-
on. Those would be for example:

Walls and ceilings (especially concrete and solar protection glazing).

Metal surfaces next to the wireless participants (e. g. aluminium construction 
of a conservatory).

Other wireless devices and powerful local transmitters (e.g. wireless 
headphones), which transmit on the same frequency. Please maintain a 
minimum distance of 30 cm between wireless transmitters for that reason.

2.2. Connection

The radio module is connected between the appliance and the power supply. It may
only be connected to flexible lines using STAK/STAS connectors. The connectors
must be locked using the locking bow.

Do not expose to continuous sun radiation 

to avoid overheating. 

The housing is not UV-resistant.

Assembly the device in a protected area (e. g. in 
the box for the blinds/marquee/shutters in a construction
profile beneath the roof tiles or in a housing). 

No water may run along the supply line and device 

because water 

can enter in via the connectors

.

Assembly the device in a protected area (e. g. in 
the box for the blinds/marquee/shutters in a construction
profile beneath the roof tiles or in a housing). 

Lay the supply lines out and down from the device.

No vibrations!

Assemble the device in a place that is free of vibrations.
