ACTIVATING AND DEACTIVATING THE UNIT

- Put the on/off switch to ON

Cooling mode:

- To switch on the cooling mode, keep button K pressed for 5
sec.The mode of operation and the pump indicator lights come
on.

One or both compressors may activate according to the tempe-
rature of the return flow of water.

Turning off:

To turn off the unit in the cooling mode, keep button K pressed
for 5 sec.

At every change of season,

make sure the operating

conditions fall within the limits specified on page 16.

Check

that the compressor current input is less than

the maximum indicated in the table of technical data.

In three-phase models,

check that the noise levels

of the compressor are not abnormal. If this is the case,
reverse one phase.
Make sure the voltage is within the established limits
and that, for three phase units, the unbalance between
the phases is less than 3%. Check that the cover is
closed again following the setting procedure

- The temperature of the water returning from the system
appears on the display:

Heating mode:

- To switch on the heating mode, keep button J pressed for 5
sec.The mode of operation and the pump indicator lights come
on.

One or both compressors may activate according to the tempe-
rature of the return flow of water.

To turn off the unit in the heating mode, keep button J pressed
for 5 sec.
