The ST1 connection is bridged by default. Do not
remove the jumper.
If the installation involves the use of thermostats
or timer-controlled thermostats to manage the
heat request, it is necessary to ensure that they
do not have a proportional-band control logic.
This logic may indeed cause inefficient behaviour
of the system and fail to guarantee the fulfilment
of the room temperature set-point. We recommend
using modulating thermostats, modulating
timer-controlled thermostats or ON/OFF thermostats
without proportional band logic.
Electrical connections
– Fasten the power cable (2) to the terminal board (M1).
– Fasten the communication cable (3) between the outdoor
and indoor units to the terminal board (M2).
– To ensure adequate resistance to pulling, the power cables
must be secured using the cable clamps (4).
