•  Modify the content of the status register structure to change the MODE parameter to zone hold mode and 

the active zone parameter to the zone which you wish to hold 

•  Send this updated status register structure back to the AGM300 using PRESET MULTIPLE REGISTER 

COMMAND to the HOLD ZONE REGISTER (0x0018h). 

•  Read the AGM300 Status Register (0x0011h) 
•  Modify the content of the status register to change the MODE parameter to normal mode and the active 

zone parameter to the zone which you would like to resume normal activity on 

•  Send this updated status register structure back to the AGM300 using PRESET MULTIPLE REGISTER
