4 Description of functions

The compressor's speed change
The compressor's greatest speed change is 6 rps/30 sec.
Compressor start
The compressor restarts if the following conditions are
met:
■The inner unit sends start signals.
■More than three minutes have passed since the
compressor was stopped.
The compressor's speed is calculated by the connected
indoor unit which requests the necessary output.
Upon first start-up in heating operating mode, after
the current has be switched on, the outdoor unit delays
the compressor start by 30 minutes, to prevent oil being
drained from the compressor.
During the delay, ”Protection” appears in menu 5.0.
Start procedure for the compressor
Process 1
The compressor usually starts with process 1.
The compressor starts at a speed of 30 rps and attempts
to meet a target speed of "55 rps" with a speed increase
of 5 rps / 5 sec.
Defrosting stops when the pressure difference exceeds
0.34 MPa in heating operation.. In cooling operation
it is stopped when the low pressure is 0.8 MPa. When
the pressure difference is achieved the target speed is
changed to "A" rps and maintained for "B" minutes.
B minA rpsState
420Cooling mode
255Heating mode
Process 2
First start after the heat pump has been powerless.
The compressor starts at a speed of 30 rps and attempts
to meet a target speed of "55 rps" with a speed increase
of 5 rps / 5 sec.
Defrosting stops when the pressure difference exceeds
0.34 MPa in heating operation.. In cooling operation
it is stopped when the low pressure is 0.8 MPa. The
compressor then holds "A rps" for "B min".
B minA rpsState
1030Cooling mode
1030Heating mode
Process 3
If both the following conditions are met:
■Restart of the compressor in heating operation if the
compressor has been stopped for 2 hours or more.
■Ambient temp. at restart is lower than 0 °C.
The compressor starts at a speed of 30 rps and attempts
to meet a target speed of "55 rps" with a speed increase
of 5 rps / 5 sec.
Defrosting stops when the pressure difference exceeds
0.34 MPa in heating operation.. In cooling operation
it is stopped when the low pressure is 0.8 MPa. The
compressor then holds "A rps" for "B min".
