In heating mode, when
T2<T2_ExitT4LowFre_ADD , and T4<-4

,
there’s frequency elevation:
elevated frequency= Recent frequency * 110%
When T2> T2_ExitT4LowFre_ADD-2 and T4>-6,
the highest frequency can’t exceed F17
When T2> T2_ExitT4LowFre_ADD-4 and T4>-8,
the highest frequency can’t exceed F18
When T2> T2_ExitT4LowFre_ADD-6 and T4>-10,
the highest frequency can’t exceed F19
For all other conditions, the highest frequency is
