actuator output is ON.
- When a LED is either off or only faintly lit, it means that the corresponding
actuator output is OFF.
- The colour of the LED provides information about the quality of radio
communication. See paragraph on "Checking the signal strength".
- A continuously blinking LED indicates the presence of a fault in the system
which requires the user's intervention. In this case the colour of the LED has
the following meanings:
Green: Error in the temperature probe of the wireless thermostat.
Yellow: Wireless thermostat battery low
Red: Absence of radio communication.
When the channel is in a fault status and the LED is blinking, it may blink in two
different ways depending on the output relay status.
If the output is inactive the LED will normally remain off but then emit a short
flash, whereas if the output is active, the LED will normally remain lit and then
go off briefly.

link between the thermostat (or chronostat) and the receiver, shown with
