8. Intelligent Controller (CZ-256ESMC2U) Things you should know Miscellaneous Indemnity This company shall not compensate in the following cases. y If the 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 You should take a note of the identification number 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. Things you should know Interface adaptors (sold separately) Interface adaptors for on/off control Using interface adaptors for on/off control enables you to connect devices (ventilation fans, room air conditioners, etc.) to turn on or off. There are the following limitations you should be aware of, however. Contact the place of purchase or your servicing agent for details. Items that can be centrally controlled Centralised control is possible only with the following items: y ON/OFF y Remote controller prohibition (only prohibiting "ON/OFF") You can also make timer settings, but settings other than "ON/OFF" and "remote controller prohibition" will be invalid. "Remote controller prohibition" is only for when local prohibition signal output is connected from the interface adaptor to the device. Alarm display "C12" (interface adaptor batch alarm) is displayed, but no details are displayed. (However, only when the alarm signal input is connected to the interface adaptor) Air conditioning distributing Indoor unit fan speed data The cumulative operating hours by fan speed will be fixed to "Mid.". Even when the thermostat ON signal input is connected to the interface adaptor, the cumulative operating hours will be counted as fixed to "Mid.". ON hours for electric heater The cumulative ON time for electric heaters is not displayed. Indoor unit performance fixed values As these are not identified automatically, set the performance fixed capacity values (kW) in the "Edit unit settings" screen (P.143). Distribution methodology Only time distribution is supported. Note y If a device meets the contact specifications as a interface adaptor for on/off control, you can control this unit from any device, but as this entails dangers to life, property, etc., it is strongly advised that you do not. y After starting distribution operation, if you change the address of an indoor unit or switch the address of an indoor unit with another, for example, distribution calculations will be inaccurate, and other problems may occur so care should be taken. 3 - 269 Control of 2WAY VRF SYSTEM Appendix Appendix Appendix Appendix $;&4.$6@0*QEG
