Fan speed control problem - Long - 22.10.2022
Hi everyone!
I have a modbus problem, need someone help. according to the modbus documentation the register for the fan control flag should be set to 6, but it's not clear to me how to set the flag for the register. Thank you very much!

Check point (2). You need to write 6 to bits 4..7 to enable fan control.

Update the profile, map an object and write 6 there.
Code:
{
"name": "1-00 Fan Control Enable",
"type": "register",
"address": 2000,
"datatype": "uint16",
"bus_datatype": "uint8",
"value_bitmask": 0x00F0,
"writable": true,
"write_bitmask": true
