J1. ON (for appliances with radiant panel, SLR type): in night mode and ambient temperature close to
the desired one, room heating occurs through natural convection and irradiation, as in traditional
radiators (under these conditions ventilation is inhibited for maximum acoustic comfort);
J1. OFF (for appliances without radiant panel, SL type): heating occurs always through forced convection,
with activation active also in night mode (at reduced speed).
J2. ON: in cooling mode, the fan remains powered even when the desired ambient temperature is
reached.
J2. OFF: in cooling mode, the fan is deactivated upon reaching the set temperature.
J3. ON (appliances to be installed in 2-pipes systems): the board is set for management of a single water
valve for summer (cooling) and winter (heating) operation.
J3. OFF (appliances to be installed in 4-pipes systems): the board is set for management of two water
valves, one for summer (cooling) operation and one for winter (heating) operation.
The three selectors can be positioned in all the possible combinations since the respective
functions are independent from each other.
At each reactivation, the display shows the code corresponding to the setting of the internal selectors for
5 seconds:
