Installation
1. Lift the lid to access the terminals.
2. Connect the receiver to the master controller via the RS485 terminal.
3. Connect the receiver to the supply voltage. The display will beep once
and two small LED lights will start blinking on the display.
4. Mount the receiver on any flat surface. If it is installed in a humid
environment, vertical mounting is recommended.
When the receiver is powered on it will automatically forward signals
received from the paired sensors and detectors to the controller.

Settings
The joystick is used to manoeuvre through the channels (see Table 1). For
each selected channel four different values are shown subsequently in the
display:
1. Current channel, e.g. 01
1
2. Received signal strength indicator (RSSI), S.1...9
S. = signal strength, 1 = weak signal, 9 = strong signal
S.- = no sensor is paired on the selected channel
Note that the signal strength abbreviation S. should not be mistaken
for number 5.
3. Value 1 for the sensor or detector (if available), 0...99. If both value 1
and 2 are available, value 1 always shows the temperature.
4. Value 2 for the sensor or detector (if available), 0...99. Value 2 can for
example show the humidity.
