Telephone Interfaced Viessmann

in THE MAIN WALL
Not sure if i am "Coding" the Viessmann correctly.

#1 charged to 011:001

#2 Changed to 027:001 ??

#3 Changed to 0C8:000

Then i set the "Reduced room temperature knob" to 60F , make and break contacts between X 4.1 and X 4.2 via a Autodailer wait for about 2 days and am finding the the temperature in the house is still around 70F.

NOT sure about the 027: 001 code? ,also is the "reduced room temperature" dial the lower setting value or is Viessmann using a "parallel shift" in the heating curve setting for the lower supply temp.?

Does anybody have experience with this setup?

Thanks Richard

    Change coding address 027 to :000 (external switching of heating program). Make sure the contacts are CLOSED on X4 1-2 for the reduced operation time. The moon dial is a "parallel shift". The other settings appear to be correct.
