1.5.5 Auxiliary Electric Heater ON/OFF Temperature
∗1. S value varies automatically based on the room temperature trend.
There is a limitation of combination between Ton and Toff as below due to 2°C (3.6°F) hysteresis
required for reliability.

1.5.6 Setting of Airflow Rate when Heating
The fan revolution is changed to maintain the sufficient distance for warm air to reach during the
heating operation. The setting should be changed depending on the installation condition of the
unit.
