2.3.2 Detailed Explanation of Setting Modes
Filter Sign Setting
If switching the filter sign ON time, set as given in the table below.
Electrical Heater Setting
Selection of the heater
The capacity of the electrical heater should be selected locally.
01: When the heating capacity of the heat pump is insufficient during heating, the heat pump is
stopped and heating operation is performed with an electrical heater. (It is switched by a hot-
water heating instruction from the outdoor unit.)
03: If heating is insufficient in heat pump system alone, an electrical heater is used as the
auxiliary electric heater.
Electrical Heater Step Setting
01: Controls ON/OFF of the heater in accordance with the thermostat step.
03: Without heater
Fan Speed Changeover when Thermostat is OFF
By setting to “Set Fan Speed,” you can switch the fan speed to the set fan speed when the
heating thermostat is OFF.
Since there is concern about draft if using “fan speed up when thermostat is OFF,” you should
take the setup location into consideration.
On warming, the priority is given to this over "airflow OFF switch on thermostat OFF".
.
This is used to correspond with the improvement of the electrical collection capability.
