By default, the Intesis device reports ambient
temperature to the IntesisHome App.
The indoor unit's return temperature sensor controls the
system base on its return temperature.
Caution:
• Intesis device shall be install inside living space.
• The ambient temperature shown in the application is
not a control temperature of the unit. The controlling
temperature is located in the return of the indoor unit.
The Fujitsu wired remote controller can be use to
control the system base on ambient temperature of the
controller.
Benefits:
• Intesis device can be install away from plain sight
without affecting ambient temperature reading in the
application.
•Application can show the control temperature.
Caution:
• Fujitsu wired remote controller shall be install inside
living space
Please follow the steps below to activate sensor of
Fujitsu wired remote controller. Refer to 9b-1 and 9b-2.
Example
If 9b-1 and 9b-2 are not set, ambient temperature on the application is
