Electronic board with continuous modulation for remote thermostat connection
The electronic board for remote control allows the control of all cooler-
radiator functions from the wall-mounted control panel .
You can connect to e remote command up to 30 cooler-radiators that will
be controlled in broadcast (with simultaneous commands to all cooler-
radiators) .
It can be installed on all versions; the board has a green LED indicating
the status and any faults .
The main operating parameters, the setpoint and the room temperature
are transmitted from the wall-mounted remote control panel ECA649 to
all connected terminals in the network, ensuring smooth operation .
For cooler-radiators use please refer to the instructions of this control
panel .
The 10 kΩ water temperature probe located in the device battery can
manage the minimum in heating (30 °C) and maximum in cooling (20 °C)
functions .
LED Signals (rif .A)
Green Led: Signals the functioning of the
device . Flashes in case of faults .
Error signals
Error
Communication error: The board is provided with a function that allows continuous
information exchange on the serial line with the wall-mounted control panel ECA649 . If it is
missing for more than 5 minutes the relative error is displayed and the device is deactivated .
Fan motor fault (for example jamming due to foreign bodies or fault in the rotation sensor) .
Water temperature probe failure for 2-pipe versions (H2).
In this case make sure the probe has 10 kΩ.
Operation of the S1 grill microswitch due to filter cleaning
Unmet water request detected by H2 probe (over 20 °C in cooling, below 30 °C in heating).
The fan will stop until the temperature reaches an appropriate value to meet the request* .
* If after powering the equipment the board detects the water probe, the start-up will take place with minimum and
maximum water temperature thresholds .
The board can also operate without a probe, case in which the fan stop thresholds will be ignored
