Add entity for low-temperature boilers pump start temp

[SMHRambo]

I have a Buderus MC10 with RC310 Controller. The MC10 is installed in an Buderus S315T low-temperature boiler. For low-temperature boilers, there is a setting available to define a minimum switch-on temperature for the pump. But the value is missing in ems-esp.

The telegram is: thermostat(0x10) -W-> boiler(0x08), UBAParameters(0x16), data: 22 (offset 23)

Could you create a Custom Entity to test this, both reading and writing? When it works, we can add it to the C++ code. That will save us hours of troubleshooting. thanks.

[SMHRambo]

I have already tested it with a custom entity. Both reading and writing work.

[proddy]

perfect, it's an easy add then. thanks.
