Ariston Nimbus and Heating Flow Temperature for Cooling

[mauropriori]

Hi, I'm using this integration with my Ariston Nimbus 70M.
This is the first year and for all the winter i've controlled the configuration, on, off, setpoint temperature with Home Assistant and i've achieved a better confort and lower power consuption.
Then... this summer i'm preparing some automations for the same scope but when i try to set the heating_flow_temperature entity to set the desired set point i get this error

Error: Value 18.0 for number.ariston_heating_flow_temperature_1 is outside valid range 22.0 - 35.0

i can't find a similar entity for the cooling temperature
i think with this limitation i cannot use manual control for the summer...
