Script humidity and heating

[Danny]

Good afternoon,
I want to create a script with the following options, but I can't figure it out.

I have a humidity measurement and a floor/room temperature.

The underfloor heating should turn on when the humidity exceeds the set value. However, the floor must not get warmer than 29 degrees Celsius. The underfloor heating should also turn on when the temperature inside reaches 5 degrees Celsius.

The ventilation should also turn on when the moisture content exceeds the set value. It's regulated from 1 to 100% and should increase in speed in several steps.

Room temperature 
3/1/1
Floor temperature
3/2/1
Humidity
4/1/1
Maximum humidity
4/2/1
Switch underfloor heating
3/4/1 (1-bit)
Ventilation
5/1/1 (1-byte)

Thanks in advance for your help.
