LED Indications (Ref . A)
Error Display
Communication error. The circuit board expects continuous information exchange on the serial
line with the wall-mounted control. If this exchange is lost for more than 5 minutes, an error
warning is displayed and the unit deactivated.
6 f pause
Problem with fan motor (e.g. blockage caused by foreign objects, faulty rotation sensor). 2 f pause
Water temperature probe fault.
In this case, ensure that the probe installed is 10 kΩ.
3 f pause
Engaging of grille microswitch S1 due to filter cleaning operation.
Continuous rapid
flashing
Water demand detected by probe H2 insufficient (above 20°C when cooling, below 30°C when
heating). Stops the fan until the temperature returns to a suitable level to satisfy the demand*.
1 f pause
* If after having powered the board the water probe is
detected, start-up takes place with the minimum and
maximum water temperature thresholds. - The board also has a function when there is no probe,
in such cases the fan stop thresholds are ignored.
- The circuit board for remote control is for all functions
of the fan coil system from the wall-mounted remote
control.
- A remote control can be connected to a maximum of
30 fan coils that will be controlled in broadcast mode
(simultaneous commands to all fan coils).
- It can be installed on all versions, the board has a
green LED that indicates the operational state and any
anomalies.
- The main operational parameters, the set point and
the room temperature are transmitted from the wall-
mounted remote control to all terminals connected to
the network, allowing unified operation.
- Refer to the instructions for this control for use of the
fan coils.
- The 10 kΩ water temperature probe positioned in the
device battery regulations the minimum level when
heating (30°C) and the maximum level when cooling
(20°C).
Continuous modulation circuit board for connecting remote thermostat
Green LED: Indicates that the unit is operational.
Flashing indicates an anomaly.
LED off: unit is off or has no power.
