I am presently restoring a Viessmann 4021 "Hobby" Block Signal. Can one of you well read folks direct me to a website or other information that would show the operating Printed Circuit Board schematic diagram and coloured wire connections. The Viessmann website and other dealer websites indicate 2 x Blue, 2 x Red, 2 X Lilac, 1 X Yellow and 1 X Brown - The Takamisawa Latching Relay is fully functional so with some help I may get this baby back into working order. Many thank's in advance.

I suggest you to follow Viessmanns printed schematic by connecting the wires correct! |
