Connection to the mains supply can be carried out with fixed connection or with mobile plug and
MUST be equipped with an omnipolar switch compliant with the current IEC EN standards, with
a contact opening of at least 3mm (better if equipped with fuses).
Correct connection to the ground system is essential to ensure safety of the
appliance.

2.1 - CONFIGURATION
The printed circuit board must be configured depending on the type of installation and based on particular
operating preferences of the machine.
The three selectors J1, J2 and J3 indicated in fig. 1 must be set as described in the next page:
J1.
ON: in night mode, heating works in natural convection and irradiation mode only, without ventila-
tion; In all the other cases of heating, ventilation switches off approximately 1°C before reaching
the desired temperature and continues in irradiation and natural convection only up to the desired
temperature.
J1.
OFF: for appliances without radiant panel: 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 upon reach the desired ambient temperature.
J2.
OFF: in cooling mode, the fan id deactivated upon reaching the set temperature.
J3.
ON: for appliances to be installed in 2-pipes systems: the board is set for management of a single
water valve (Yc) for summer (cooling) and winter (heating) operation.
J3.
OFF: for appliances to be installed in 4-pipes systems: the board is set for management of two water
valves, one for summer (Yc - cooling) operation and one for winter (Yh -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:
