4.4 HOW TO MAKE THE ELECTRICAL CONNECTION FOR SUMMER
OPERATION
To change from winter to summer operation (fan operation only), follow the instructions
below.
You will need:
the heater connected to the power and gas supply.
1.
Close the gas valve and disconnect the appliance from the power supply.
2.
Access the instrument panel and move the "electrical bridge" from the WINTER
position (terminals 1-3) to the SUMMER position (terminals 1-2) (see Figure 18 on
page 30).
3.
Power the appliance: in this way only the fan(s) will operate, providing a pleasant
movement of air in the room.
4.
At the end of the summer season, to change from summer to winter operation, it is
necessary to move the "electrical bridge" from the SUMMER position (terminals 1-2)
to the WINTER position (terminals 1-3).
Alternatively, rather than performing the operations described above, to change easily and
immediately from summer to winter operation and vice versa, it is possible to replace the
supplied control box with a command equipped with a summer/winter button (available as
an accessory - O-CTR000 - see Figure 17).
