2 FEATURES
WRR 1 is a multifunction built-in mini receiver for indoor
use, which can be in wireless control of connected lighting,
alarm, HVAC and applicable in house, office, small-scale
store etc.
Advantages:
Compact size, built-in design with 21 mm thickness,
completely free installation in the wall by existed junction
box. .
Receiver works on band of 433MHz, the reception range
can therefore reach 20-30m in open air. It provides
interference-free with well stability.
Red LEO are designed as clear indicators, red one is to
specify signal reception, code learning / deleting
operation.
6 precise time adjustments for convenient selections.
With external push button, the lighting can be switched
on / off manually.
Potential free contact can fit different way of wiring.
3 INSTALLATION ANO WIRING
A Please disconnect power completely and read the
~ entire instruction manual carefully before installation.

3.2 Helpful tips for a better reception
"OTE
Keep the antenna straight while installing, otherwise,
please organize the antenna around the receiver
properly (See FIG.2-A).
00 NOT cut or lengthen antenna voluntarily to avoid
danger or shortening reception range (See FIG.2-B).
00 NOT connect antenna with power cables to avoid
receiver damaged (See FIG.2-C). Please be noted not
to strip off antenna sheathing to avoid electrical shock.
For a better reception, please pay attention to the followings
while installing.
To install WRR1 at least 1m high from floor since ground
is the best radio wave absorber. The higher of mounting
position is, the better of reception performance obtains.
Make sure transmitter and WRR1 are ali within effective
working range.
Keep WRR1 at least 1m away from any conductive
devices such as aluminum reinforced UPAC, metallic
window and door or electric cables etc to avoid
shortening transmission range.
Avoid installing WRR1 on thick wall that blocks the
transmission and the reception of radio waves and
shortens the working range.
Ouring installation, keep WRR1 at least 2m away from
other same frequency receivers to avoid interference or
shortening transmission range (See FIG.3).

4 CODE SETTING
The receiver must complete learning procedure to identify
the radio signal (10 number) of the transmitter in order to link
.each other. Each transmitter is already assigned an
individuallO code number before ex-factory to register a
transmitter to a receiver by learning transmitter specific 10
code number for activating a valid radio command.
Combined transmitter is taken example for WT2 (See FIG.8).
NOTE
Make sure the power supply connects well before
learning the code.
The working range of learning code to be teach-in or
deleted for combined transmitter and receiver is between
0.5m and 5m to assure successfullearning.
Each receiver can store up to 20 different transmitter
codes, the first code set will be deleted while the 21 st is
teach-in.
Learning code can be teach-in or deleted only under
learning mode .

transmitter or manually controlled by contact external push
button switch.
In normal operation mode, the connected load and the
can be switched on Ioff manually at any time by
simply pressing the learning ( ~ 1sec) button of WRR 1
(See FIG.8).
This can be used to test if the load works normally and wiring
is connected correctly.

5.3 Auto off timer knob setting
NOTE
Time knob must be set at right position of value figure
marked. 00 NOT set knob between two value figures to
avoid value confusion. I.e. If set the value between"4H"
and "00" but the desired value is "4H", therefore, the time
setting may be "4H" or "00".
When receiving an effective ON signal, time of WRR1
starts to run and the lighting turns on until time setting is
elapsed. Ouring timer ON period, the lighting will turn off
either by receiving an effective OFF signal or by manual
switch off.
WRR1 has 6 precise TIME adjustments: JiS'LI 3m. 130m. I
1H. I4H. 100. Can be adjusted according to user's
desire. Time knob is set to "1 H" ex-factory (See FIG.11).
