Grafik Eye with timeclock

Hi all,


I'm planning on buying a 4 zone grafik eye system, the 3104

I want to be able to have the lights controlled by a timeclock so I though of buying the GRX-PRG programming interface with built-in timeclock. This way I can setup the timeclock through a pc.


I also will have a keypad in my home cinema to control the grafik which will be placed in an aother part of my house.


My question ;


will the keypad in my home cinema room overrule the timeclock? Let's say my lights are activated at 7 o'clock in the evening. If I would come home around 9 o'clock my lights will be on, great! Can I turn of the lights by simply using the keypad in my room or do have to turn of the timeclock in some other way?


Also read some stuff about the grafik 3504 which can be entirly controlled through a pc. Is this really a good feature, is it worth the money or should I stick with the 3104 which can be used for with the GRX-PRG also?


Thanks!
