6 Optional functions
F3 – Automatic reset of setting temperature (PC-ARF) / Not available (PC-ART).

mode or operations using the remote control for the central unit are forbidden.
This function is used to economise the operation. When this function
is valid, the temperature configuration is automatically initialised
for Cooling/Heating (55/56) under the following conditions:
• If the automatic temperature Reset (54) is not performed du-
ring temperature configuration.
• If it is effective for optimum temperature configuration and
energy is saved.

In case that the set temperature is changed and kept within the set time at "F4", the temperature is automatically
changed to "F5" and "F6". In case that the set temperature is out of range at "F5" and "F6", it is applied within
upper and lower limit for the set temperature.
