Error when enabling Switch enable_fixed_system_supply_set_point

[de0021]

Hi,

Benn running Home assistant and this integration for a few months and works great.

Just got o problem yeasterday when trying to enable the switch "enable_fixed_system_supply_set_point".

If I deactivate it and reload the integration it starts working again.
Running Version 13 on the heatpump and 23.5

Thanks :)
