If operation of the appliance is arrested several times, contact an authorised Robur
Technical Assistance Centre (TAC).
When activation is successful, the appliance is managed by the electronic board (see
following paragraph).
2.2 ON-BOARD ELECTRONICS
The following descriptions refer to the electronic board with firmware version 3.016.
If the appliance is connected to a Direct Digital Controller (DDC):
if the DDC is in controller mode, control of activation and deactivation of the
appliance occurs exclusively via the DDC. If the DDC is in "monitor" mode, control of
activation and deactivation of the appliance occurs via the on/off commands
provided by the electrical installation technician. For instructions regarding the use of
the DDC, refer to the two books supplied with it, and in particular manual 2:
"final user manual - book 2".
The appliance is equipped with a microprocessor-controlled S61 electronic board
interconnected with an AR10 satellite board, located on the side of the S61 board itself
(see Figure 1, page 8).
The S61 electronic board , contained in the electrical panel, controls the appliance and
displays data, messages and codes during operation. This is how the S61 appears, with
its main components highlighted:

Programming, control and monitoring of the appliance take place by interacting with the
display and encoder of the board. The CAN bus port allows one or more appliances to be
connected to a Direct Digital Controller (DDC).
The AR10 satellite board (see Figure 1, page 8) is used for connecting the inversion
valve and the defrosting valve.
