4 2. FEATURES DESCRIPTION This unit shall be installed as a medium between in Building Management System (BMS) which provide with LonWorks interfaces, and Midea central A/C system, associating these two systems to realize the systems integration. BMS is allowed to access any online A/C in Midea central A/C system for information collection and operation control, after proper installation Midea A/C, the 3-Generation Central A/C Monitored Control System and this unit. 2-1 Information Collection This unit is provided a function that collecting information from Midea central A/C by BMS, which operation states' data of indoor units and outdoor units within A/C system could be obtained by modify the corresponding LonWorks network variables. Refer to Operation Instances for detail operation examples, and see Network Variables charts for specific information variables. 2-2 Operation Control The unit provides BMS control Midea central A/C, with six setting functions to control the indoor units in which of the system. Setting functions included Operation mode setting, Open time setting, Close time setting and Auxiliary function setting. By modify the corresponding LonWorks network variables to set the unit's operation status. Refer to Operation Instances for detail operation examples, and see Network Variables charts for specific information variables. Hardware Software PC Electric meter WHM The 3-generation network external assembly Uninterrupted power supply UPS Other Operation system Equipment specifications Recommendation CPU: Pentium 4, above 2G main frequency hard disk, not less than 40G; Intenal storage: More than 512M; Lenovo, Dell Communication terminal: Not less than 2 items of products RS-232 terminal, and 3 items of USB terminal. Functions: The meter can alter electric address as per to convention dynamic state, and can read the reading data from electric meter according to dynamic address input by main board. Includes: Installation manual,soft lock dog, and transition port Capacity: 200~250 W/20min; Voltage: As per practical operation; Control signal: Power cut signal. With 3-cord shielded twisted pair line WIN2000/WINXP The 3-generation moniter software Mircosoft SQLServer 2000 Personal edition (Personal Edition) Chint DTS634 or relevant model APC Su700 series Note Recommending to use XP system shall be installed Sp4 or above, otherwise SQL Server could not be installed properly. 2

5 3 OPERATION INSTANCES 3-1 Reading Operation Data from Indoor Unit: BMS read data from indoor unit which main unit address is 6, network address is 1, process as following: 1) Modify the network variable nvimainaddr=6, therefore, set the A/C main unit address as 6; 2) Modify the network variable nvimainaddr=1, therefore, set the A/C NET network address as 1; 3) Modify the network variable nvigetlasvalue= , convey the latest information of which set equipment to LonWorks. Needs to renew the system once only, the system return all information from the appointed A/C at a time, of which corresponding network variable would be refreshed automatically. 3-2 Setting Operation Modes for Indoor Unit BMS read data from indoor unit which main unit address is 8, network address is 2, process as following: 1) Modify the network variable nvimainaddr=8, therefore, set the A/C main unit address as 8; 2) Modify the network variable nvimainaddr=2, therefore, set the A/C NET network address as 2; 1) Modify the network variable nvisetworkmode= HVAC_COOL, therefore set the appointed equipment service at cooling mode. Enactments include: Operation mode setting, Air speed setting, Temperature setting, open time setting, close time setting and auxiliary function setting, each time with only one kind of enactments by Data set to control A/C equipment. Combination operate setting shall be set time after time. Readable variables and writable variables is individually in LonWorks network, thus the amendment of the network variable nvisetworkmode would not reflect at network variable nvoworkmode at once, unless the network variable nvoworkmode have been renew by BMS. 3-3 Reading Operation Data from Outdoor Unit BMS read data from indoor unit which main unit address is 9, network address is 16, process as following: 1.Modify the network variable nvimainaddr=9, therefore, set the A/C main unit address as 9; 2.Modify the network variable nvimainaddr=16, therefore, set the A/C NET network address as 16; 3.Modify the network variable nvigetlastvalue= , convey the latest information of which set equipment to LonWorks. Needs to renew the system once only, the system return all information from the appointed A/C at a time, of which corresponding network variable would be refreshed automatically. 3

6 This system adopts the manner of shared network variable to manage A/C system, which cannot access the appointed A/C within central A/C system, until the main unit address nvimainaddr and network address nvinetaddr are modified to the one that is intended to access, such main unit address variable is nvimainaddr, network address variable is nvinetaddr, refresh variable is nvigetlastvalue, and the rest parameters refer the following table. 4-1 Table of Operation Data Reading Table of Indoor Unit Network Variables Table 4.1 Model information Operation mode Mode locking state Indoor fan state Setting temperature Ts See annexed table for detail1 = HVAC_NUL = -1 Mode have not been set =HVAC_AUTO = 0 Auto mode =HVAC_COOL = 3 Cooling mode =HVAC_HEAT = 1 Heating mode =HVAC_DEHUMID = 14 Dehumidified mode =HVAC_FAN_ONLY = 9 Fan only mode =HVAC_OFF = 6 Off mode = HVAC_NUL = -1 Mode have not been locked =HVAC_AUTO = 0Lock on auto mode =HVAC_COOL = 3Lock on cooling mode =HVAC_HEAT = 1Lock on heating mode =HVAC_DEHUMID = 14 Lock on dehumidified =HVAC_FAN_ONLY = 9Lock on fan only =ST_LOW = 1 Low speed =ST_MED = 2 Medium speed =ST_HIGH = 3 High speed =ST_ON = 4 Auto 16~32 stand for 16~32 Setting temperature T1 Evaporator pipe temperature T2A Mid-part of evaporator pipe temperature T2B Condenser pipe temperature T3 Compressor current 0~200 stand for current 0A~200A Humidity 0~100 stand for relative humidity 0% 100% 4

20 DE - COMMISSIONING DISMANTLING & DISPOSAL This product contains refrigerant under pressure, rotating parts, and electrical connections which may be a danger and cause injury! All work must only be carried out by competent persons using suitable protective clothing and safety precautions. Read the Manual Risk of electric shock Unit is remotely controlled and may start without warning 1. Isolate all sources of electrical supply to the unit including any control system supplies switched by the unit. Ensure that all points of electrical and gas isolation are secured in the OFF position. The supply cables and gas pipework may then be disconnected and removed. For points of connection refer to unit installation instructions. 2. Remove all refrigerant from each system of the unit into a suitable container using a refrigerant reclaim or recovery unit. This refrigerant may then be re-used, if appropriate, or returned to the manufacturer for disposal.under No circumstances should refrigerant be vented to atmosphere. Where appropriate, drain the refrigerant oil from each system into a suitable container and dispose of according to local laws and regulations governing disposal of oily wastes. 3. Packaged unit can generally be removed in one piece after disconnection as above. Any fixing down bolts should be removed and then unit lifted from position using the points provided and equipment of adequate lifting capacity. Reference MUST be made to the unit installation instructions for unit weight and correct methods of lifting. Note that any residual or spilt refrigerant oil should be mopped up and disposed of as described above. 4. After removal from position the unit parts may be disposed of according to local laws and regulations. UG-AMR07Y/E ENGLISH
