RX RECEIVER SETTINGS
12.1.
Establishing a connection between 4020TX thermostat and RX receiver or
receivers (pairing)
Each thermostat and each receiver has a unique number that distinguishes it from others. It is
not possible for any thermostat not paired with the particular receiver to interfere with the
operation of another pair or set.
The thermostat may be paired with other receivers at any time. A blackout, battery
replacement as well as a complete reset of all thermostat settings do not affect the pairing of
devices in any way.
Pairing procedure:
•
Enter the configuration mode in the thermostat
•
Select the pairing mode (P)
•
Press the central button
–
the display shows 0
•
Insert the receiver into the plug socket
•
Press the button on the receiver 3 times
–
the blue LED lights up
•
When the receiver is detected, the display shows OK and the digit 1 (first receiver)
•
If you are using only one receiver, press the central button and exit the menu. The
pairing mode is ended.
If you are going to pair multiple receivers (maximum 6), proceed as follows:
•
When the first receiver is detected (digit 1 on the display),
•
insert the second receiver into the plug socket.
•
Press the button on the receiver 3 times
–
the blue LED lights up.
•
When the receiver is detected, the display shows 2 (second receiver).
•
Proceed similarly with the connection of subsequent receivers, then press the central
button and exit the menu.
Caution!
The pairing mode is available for 10 minutes after the receiver has been connected to
the mains!
Factory-established thermostat-receiver pairs are paired, however, pairing may be
repeated if necessary.
