temperature remains 35 ºC for more than 4 minutes
• The fan motor works as set if the he heat exchange
temperature remains above 38 ºC.
When the compressor stops and remains idle for 3
minutes
20 seconds after the compressor stops, the up wind
volume is weak (switching to SSLO in silent running
mode) and then slightly weak. While the down wind volume
is stoped. If the compressor stops when the heat running
starts, the wind volume is weak.
High Work-intense protection control
Under the heating mode, the high work-intense protection
will be carried out according to the heat-exchange temperatures as shown in the table below.
Low Work-intense protection control will be neglected in
the trial running.
Low Work-intense protection control will be cancelled for
3 minutes temporarily after the powerful cooling starts
for 1 minute.
