Then there is possible to change relay status by Modbus communication protocol command by
requested value writing to following addresses:

Description Status
Far condition for Relay1 0x0042 66
0 ... Relay1 open
1 ... Relay1 closed

With Modbus communication protocol there is possible to set regulator’s parameters described at
chapter „ Actual regulator preset” at page 10. Follow next steps:
1) To address 0x0044 (68) write value1 – it enables Modbus setting. By the way it blocks
regulator’s keyboard – local keyboard is blocked during remote control setting change.
2) Write the desired settings / changes to the addresses from 0x0045 (69) to 0x004E (78). New
setting can be done simultaneously or each register can be written alone
3) To address 0x004F (79) write value 1. Once this step is done, new setting is physically stored
into device memory (confirm change). Then registers 0x004F (79) and 0x0044 (68) are
automatically cleared (zero). It automatically unlocks the keyboard too.
Whole setting process can be cancelled by writing value 0 to address 0x0044 (68). At this time no
changes are stored and last setting stays valid.
