Miscellaneous
Indemnity
This company shall not compensate in the following cases.
y If the identification number (password) is found out by a third party and problems result
y If a USB memory device malfunctions and backed up data (accumulated data, distribution data) is lost
Where large errors can occur in calculation
Some models (semi-centralised models, floor mounted models, etc.) and old models with electric heaters for example, may show large
differences in calculations of air conditioning distribution ratios. Furthermore, if you use large pan type humidifiers that use a lot of power, the
operating times of the humidifiers will not be reflected in the calculation of the distributions, leading to a large difference.
Contact the place of purchase or your servicing agent for details.
Remote control-less systems
In a system without remote controllers where only one centralised device has been installed, if that device breaks down then you may be faced
with the problem of not being able to run the air conditioning units. It is our recommendation to install multiple centralised devices for safety
purposes.
The identification number (password)
You should take a note of the identification number (password) and keep it in your records. You should also take care not to reveal the number
to a third party.
Contact the place of purchase or your servicing agent if you forget the number.
Screen disruptions
There may be some disruption to the screen when it is refreshing, but this is not indicative of a malfunction.
