Green LED blinking: there is a problem in communication with
the active antenna or with other modules connected in the
chain (for example, there may be a problem with the data
cable connection)
Actuator output "1 - 2" status LEDs (
There are 2 status LEDs, each of which corresponds to a
channel, and they may light up green, yellow or red.
Each LED provides information about the output and the
radio thermostat controlling it.
In general, the following rule should be borne in mind:
- When a LED is lit, irrespective of colour, it means that the
corresponding 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 thermostat
transmitter.
Yellow: Thermostat transmitter battery low.
Red:
Absence of radio communication.
When a channel is in a fault status and the corresponding
LED is blinking, it may blink in two different ways depending
on the output relay status.
If the output is deactivated the LED will normally remain off
but then emits a brief flash, whereas if the output is active,
the LED will normally remain lit and then go off briefly.
Auxiliary output on/off LED "
The yellow LED, marked by the "
status of the auxiliary output relay.
- LED on:
auxiliary output ON (the pump or boiler
- LED off: auxiliary output OFF.
