No. Temperature scope Frequency limitation
1 Wh_c<-12 Max_hz8 120 HZ
2 Wh_c<-8 Max_hz7 120HZ
3 Wh_c<-2 Max_h z4 120 HZ
4 Wh_c<5 Max_hz5 120HZ
5 Wh_c<12 Max_hz1 100HZ
6 Wh_c<18 Max_hz2 56 HZ
7 Wh_c> 18 Max_hz6 44 HZ
Remarks: the above are the maximum frequency limitations of the complete appliance which are
affected by the environment, and they have nothing to do with the ability of the indoor unit.

Serial No. Temperature scope Frequency limitation
1 Wh_c<16 Max_hz1 26 HZ
2 Wh_c<24 Max_hz2 40 HZ
3 Wh_c<32 Max_hz3 58 HZ
4 Wh_c<44 Max_hz4 80 HZ
5 Wh_c>44 Max_hz5 40 HZ
Remarks: the above are not only the maximum frequency limitations of the complete appliance
which are affected by the environment, but also the maximum ability limitation of the system.
When the starting ability is not the maximum, its maximum frequency limitation is calculated by
the following equations:
The frequency limitation which is affected by the temperature and under the condition of actual
ability
the actural running system ability*the maximum frequency which is limited by the
temperature and under the condition of maximum ability/the maximum designing ability of the
system
T= Ti*Pi / Pi ( Ti=|Tst_i-Tnh_i the indoor environment temperature| ;Pi i the
ability of the indoor unit)
