exchanger is ≤ 56°C. When this conditions occurs, Outdoor Unit’s fan may be started again.
A further intervention level of overload protection in Heating mode foresees that if temperature detected
by TP1 sensor is at least 63°C, forced stop of compressor and fan on Outdoor Unit is commanded, and
after 2 minutes 4-way valve moves to OFF position. Rotation speed of Indoor Unit’s fan will correspond
to the speed set by IR remote control.
The intervention of this protection level will end after 6 minutes, as soon as normal operation (restart)
of system will be restored in Heating mode. However, irf within 10 minutes the required condition for the
intervention of this protection level occurs, Control PCB on Indoor Unit will command the OFF all devices
and the corresponding malfunction indication will be displayed.

The levels of intervention of protection function against overload in Heating mode are shown in “Diagram
