[kwertie01]

In this PR I added new features for the Moduline 400 Thermostat.

I added 5 parameters of the 0x3A telegram from the Moduline 400 (RC30) thermostat. (RC30wwSettings)

• wwmode
• wwwhenmodeoff
• wwdisinfect
• wwdisinfectday
• wwdisinfecthour

I added 7 parameters of the 0x40 telegram from the Moduline 400 (RC30) thermostat. (RC30Temp)

• heatingtype
• controlmode
• nighttemp
• daylowtemp
• daymidtemp
• daytemp
• holidaytemp

Added reading/writing of the switch points (switchtime1) of the Moduline 400 (RC30) clock program (0x3F telegram) including the following parameters:

• program
• pause
• party
• vacation
• holiday

Looks good.
While checking i've seen some old bugs: the RC20 also uses T1-T4, but masks wrong with & 1 when reading and set_switchtemp checks input to max 3 instead of 4. I 'll fix this later, or, if you like, you can add to this PR.

[kwertie01]

I'm a little bit ashamed and must admit that I didn't test the set_switchtemp properly. You are right that this is not working correctly now. I can set it using a number <3 but not using the letter T in front and/or number 4.
I see indeed that the mask for RC20 is &1. (old bug)
I will change/fix this in this PR.

@MichaelDvP you can approve the Merge request if you're fine with the additions.

@MichaelDvP The (old) bug of the RC20 mask and the set_switchtemp for the RC30 are fixed.

[MichaelDvP]

Thanks, only one remark:
The RC20 also have T1-T4, please set in line 2501 max_on = 4, then you don't need the if for RC30. And you can set the RC20 text to FL_(nighttemp1) (line 3697) to make it perfect.

[kwertie01]

I saw your remark too late and already created the disable usage of T0 for RC30 in set_switchtime commit.
In the second commit, I implemented your remarks.

[MichaelDvP]

Perfect, @proddy: i don't have more remarks, please merge.
