8.4.11 Follow me (optional)
1) If the indoor PCB receives the signal which
results from pressing the FOLLOW ME button
on remote controller, the buzzer will emit a
sound and this indicates the follow me function
is initiated. But when the indoor PCB receives
signal which sent from remote controller every
3 minutes, the buzzer will not respond. When
the unit is running with follow-me function, the
PCB will control the unit according to the
temperature from follow-me signal, and the
temperature collection function of room
temperature sensor will be shielded, and the
error detective function of room temperature
sensor will be still invalid.
2) When the follow-me function is available, the
PCB will not respond according to the setting
temperature from follow-me signal every 3
minutes.
3) The PCB will take action to the mode change
information from remote controller signal, and
the follow-me function will be turned off. (if the
wired remote controller does not initiate follow
me function).
4) When the unit is running with follow-me
function, if the PCB doesn’t receive any signal
from remote controller for 7 minutes or
pressing FOLLOW ME button again, the
follow-me function will be turned off
automatically, and the temperature collection
function of room temperature sensor will be
available, the PCB will control the unit
according to the room temperature detected
from its own room temperature sensor and
setting temperature.
5) When the indoor PCB receives the follow-me
signal from wired remote controller, the control
is the same as that from wireless remote
controller, but buzzer will not emit a sound.
When the PCB receives turning-off follow-me
signal from wired remote controller, the unit will
quit follow-me function at once. The follow-me
function controlled by wired remote controller
prevails that by wireless remote controller.
