FF
– Lock function for timer
This function is used to lock timer activation.
H1
– Maintenance alarms
This function is used to display or hide maintenance alarms.
H2
– Automatic control indication
This function is used to display or hide the automatic control indication.
H3
– Operation mode change restriction
This function is used to configure restrictions to the HEAT mode.
H4
– Operation modes for the ventilation unit with energy recovery
This function is only available for the ventilation unit with energy / heat recovery.
J3
– Run indicator color
This function is used to set the run indicator colour.
Setting conditions Colour
00 Green
01 Red
J8
– Eco-operation
This function is used to optimize 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.
