3 New Parameter descriptions found

[dasSofa]

I found new Parameter descriptions by tinkering with my
Alpha Innotec WZSV 62K3M Version V3.89.5

Channel 252 : T-HG max (Celsius)
Channel 259 : Ausgang 9 (Bool) Output 9 on the Mainboard - used for cooling active Signal for Room thermostat switching between heating and cooling. If you have the Expansion board installed, this Signal comes then from Channel 140 descriped as FP3out.
Channel 260: Freigabe Kühlung (Seconds) enable Cooling

Channel 267: descriped as "Desired_Room_Temperature" gets me only the constant value 2147483647 . I dont have an RBE so maybe thats why i dont get a proper temp value there.
