The outdoor unit has better efficiency than the electrical heater. Therefore, the
electrical heater is limited and turned OFF first. The system limits power

1 Turns OFF the backup heater.
2 Limits the outdoor unit.
3 Turns OFF the outdoor unit.
Example
If the configuration is as follows: Power limitation level does NOT allow operation
of backup heater (step 1).
Then power consumption is limited as follows:
