(f) Selection of max. required frequency by heat exchanger temperature
(i) Maximum required frequency is selected according to the outdoor heat exchanger temperature (Tho-R) during
cooling/dehumidifying or according to the indoor heat exchanger temperature (Thi-R) during heating mode.
(ii) When there are 3 indoor heat exchanger temperatures (Thi-R), whichever the highest applies.
When there are 2 outdoor heat exchanger temperatures (Tho-R), whichever the higher applies.
