Description of controls and operation


The receiver is already paired at the factory with the corresponding Techno device. Should it be necessary to repeat the operation, proceed as follows taking care to operate with a single pair at the time: each receiver can be paired with one Techno device only.
Power the receiver device and proceed to pair it with the Techno device.

  • Press button A for about 5 seconds until the LED B turns on and turns red to indicate that the procedure is in progress.
  • Follow the instructions of the Techno device to activate the pairing procedure with the receiver.
  • Wait for the LED B to become flashing green, the pairing procedure is complete.
  • After 5 seconds after the procedure has been completes, the LED B becomes fixed green and the receiver is ready.

To verify the correct operation of the system, on the transmitter:
Winter mode: set a temperature higher than the temperature detected and make sure that the symbol on the display turns on.
Summer mode: set a temperature lower than the temperature detected and make sure that the symbol  on the display turns on.
Check the tripping of the relay on the receiver and the activation of the controlled load.


Off: receiver off
Fixed green: receiver active
Fixed red: receiver pairing with Techno device
Flashing green: pairing complete
Flashing green/red: the communication with the Techno device has been interrupted for more than an hour. The load is not active. Normal operation is restored automatically when the radio communication is reactivated.

Possible cause
  • Check the connections of the power supply to the terminals

The system does not turn on correctly

Possible cause
  • Check the settings of the Techno device paired;
  • Check the connections of the load to the terminals of the receiver.

Communication problems between the receiver and the transmitter

Possible cause
  • Try changing the position of the receiver.
