BACnet Gateway Kit for Central Air Conditioners
38
Instance Number: YYY*8192+ZZ*64+1
Description: this object is used to monitor the error code of the GMV water heart. For more
details see Appendix E�
Present_Value:
0x00010000-0x0001FFFF (See Appendix E)
Note :
1) When some error occurs to the GMV water heater, Present_Value property will be a decimal
numeral related to the error code.
2) Multi errors may concur. Each error has a independent error code, e.g. 0x00000040 for “Water
Tank Upper Temp Sensor Error”, 0x00000080 for “Water Tank Lower Temp Sensor Error”. When
these two errors just happen together, Present_Value property will be192 (conversion method:
0x00000040 OR 0x00000080 is 0x000000C0,equal to192).
3) This parameter is only for the GMV water heater.
(19) Water tank temp(status)
Member number :18
Object name:WaterTankTempStatus_XX_YYY_ZZ (XX means Air condition type, like GMV
is 01;YYY means Outdoor Unit's number, like GMV is between 001 and 004 now;ZZ means
Indoor Unit's number, like GMV is between 01 and 16 now, otherwise 00 means device YYY's
Parameters.)
Object type: Analog Input
Object ID: AI(0)+YYY*8192+ZZ*64+1
