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.
8.4.12 Mode conflict
The indoor units can not work cooling mode and heating at same time.
Heating mode has a priority.
(1) Definition
No: No mode conflict;
Yes: Mode conflict
(2) Unit action
In case of one Indoor unit working in cooling mode or fan mode, and another indoor unit is set to heating
mode, the indoor unit working in cooling mode or fan mode will change to off. The outdoor unit will
change to heating mode after compressor stop 3 minutes. .
In case of one Indoor unit working in heating mode, and another indoor unit is set to cooling mode or fan
mode, the indoor unit setting to cooling mode or fan mode will change to stand by. The outdoor unit will
continue working in heating mode.
If heating mode stops (not including the indoor unit in heating mode reaching the set temperature), 3
minutes after the outdoor unit restarts and works in cooling mode or fan-only mode.
