Radio coupling of transmitter and receiver
The transmitter/thermostat is already paired with the receiver at the factory. If for some reason the
devices are still not tuned to each other, the following steps must be carried out to re-couple the devices
1.
The distance between transmitter and receiver should be at least 1 metre.
2.
If the red LED on the receiver is currently lit up, press the receiver's on/off button briefly to
switch it off (no LED should be lit up!).
3.
Now keep the receiver's On/Off button pressed until the yellow LED is permanently lit.
4.
Now set the lower switch (8) of the transmitter/thermostat to ON.
5.
Carefully pull the setting wheel of the transmitter/thermostat upwards, if necessary lift the
setting wheel carefully from the right side using a screwdriver.
6.
Briefly press the small black button under the dial.
7.
The display of the transmitter/thermostat switches off briefly and then shows 1. The yellow LED
of the receiver lights up 6 times simultaneously and then goes out.
8.
The units are now coupled. Put the setting wheel back on and switch the receiver on again (red
LED lights up).
9.
To check whether the coupling works, simply turn the setting wheel to the highest temperature.
The receiver now switches on and the red and green LEDs light up.
Error messages
E1
= Check temperature sensor, possibly defective or short circuit
E2
= Receiver not found, check if out of range, or repeat radio coupling.
Battery symbol in the display
= battery voltage is decreasing, the battery should be changed soon.
