NOTE: If not abide them strictly, it may cause slight or medium damage to the unit or the people. This sign indicates that the items must be prohibited. Improper operation may cause severe damage or death to people. This sign indicates that the items must be observed. Improper operation may cause damage to people or property. WARNING! This product can’t be installed at corrosive, inflammable or explosive environment or the place with special requirements, such as kitchen. Otherwise, it will affect the normal operation or shorten the service life of the unit, or even cause fire hazard or serious injury. As for the above special places, please adopt special air conditioner with anti-corrosive or anti-explosion function. 2 Operation Notices The power supply for all indoor units must be unified. Prohibit installing the wired controller at wet or sunshine places. Do not knock, throw or frequently disassemble the wired controller. Do not operate the wired controller with wet hands. This product is applicable to VRF unit, Big Duct Type unit, Air- cooled Packaged unit and U-Match unit whose outdoor unit and indoor unit communicate with each other by live line and neutral line. 1
When two wired controllers control one (or more) indoor unit(s), the address of wired controller should be different. Functions with “*” are optional for indoor units. If a function is not included in an indoor unit, wired controller can’t set the function, or setting of this function is invalid to the indoor unit. Please pay attention to below items when matching with VRF unit: When the system mode priority is the master-slave mode, in one system network, you must set one indoor unit as the master indoor unit, other indoor units are slave indoor units. When the system mode priority is the master-slave mode, the operation mode of the system is basing on that of the master indoor unit. The master indoor unit can be set to any mode (including auto mode), while the slave indoor unit can’t set to the mode that conflicts with the system mode. When the system mode priority is: Cooling mode is prioritized, heating mode is prioritized, first-set mode is prioritized, or last-set mode is prioritized. The indoor unit can be set to any mode (excluding auto mode). The indoor unit will automatically switch to the system mode, when the operation mode of the indoor unit conflicts with the system operation mode. When the system mode priority is the voting mode (indoor unit’s capacity is prioritized / number of indoor units is prioritized). The indoor unit can be set to any mode (excluding the auto mode). The indoor unit will be stopped, when the operation mode of the indoor unit conflicts with the Owner’s Manual 2
Owner’s Manual system operation mode after voting. System mode priority defaults to master-slave mode, and only certain units have other system mode priorities.
