5 Optional functions
Optional functions through Remote control
J4 – Not used
J5 – Not used
J6 – Not used
J7 – Not used
J8 – Eco-operation
This function is used to optimise the setting of temperature and provide energy saving.
When the setting temperature is changed during the air conditioning operation and while the operation is started/stopped
by RUN/STOP on the remote control switch, the set temperature automatically returns to "Automatic Reset Temperature
for Cooling/Heating (F5/F6)" (as shown in the next illustration).
However, the setting temperature is not automatically reset in the case that "Automatic COOL/HEAT Operation" mode, or
"Prohibiting Operation by Remote Control Switch" is set by the centralized controller.
Operation mode:
COOL
DRY
FAN
Operation mode:
HEAT
Jg – Not used
JA – Not used
Jb – Not used
k1 – Not used
k2 – Not used
k3 – Not used
k4 – Not used
k5 – Detection level of the motion sensor kit
This function is used to determine the amount of human activity depending on the reaction rate.
When "High" is set, the detection level becomes more sensitive. When "Low" is set the sensor becomes lower.
Human activity
Large
Small
Not available
k6 – Selection of allowed operation modes
This function is used to select the operation modes in which the setting of C8 (use of remote control switch sensor or
remote sensor on THM4 to control the indoor unit) is enabled.
