Outline With the human presence signal and the floor temperature signal from the optional sensor kit, the
system provides the energy saving control, or the comfortable temperature control and airflow
direction control preventing the direct draft to the human.
To use sensor related functions, a wired remote controller (BRC1E73) and optional sensor kit
(BRYQ60A2W(S)) are necessary to be installed.
Details 1. Draft prevention (with presence sensor)
When the sensor detects human presence during auto-swing operation, the system sets the airflow
direction parallel to the floor (position 0) to reduce unpleasant draft.
The operation returns to the normal auto-swing as the sensor detects no human in the room.
Draft prevention is enabled only when decoration panel BYFQ60C2W1W(S), sensor kit
BRYQ60A2W(S) and wired remote controller BRC1E73 are connected to the main unit and
draft prevention is set to “enabled” on the wired remote controller.
Factory setting is “disabled”.
Draft prevention cannot be activated when individual flap control is set, even if draft prevention
is enabled on the wired remote controller.
