a a The ST1 connection

a a 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).
