Each time the button is pressed the three operating modes are started in turns:
AUTOMATIC
("AUTO" led: ON)
In this operating mode, the receiver receives a radio signal coded by the chro-
nothermostat via the transmitter interface and triggers the integral relay. The
"POWER ON" led takes on a different colour according to the quality of the
signal received:
• RED: signal absent or very disturbed
• ORANGE: satisfactory reception
• GREEN: good reception
Fast and brief led fl ashing indicates the reception of radio data sent by the
transmitter.
