Hi there,
could anyone help me a with wiring diagram for the danfoss 103E, not sure how it`s working but was installed when the central heating was installed on a fully pumped system. Listed below is what connections are in place upon it.
A fused spur with red. black and earth
one incoming 4 core with yellow, red, blue and earth.
one incoming 3 core with red, black and earth.
nothing in terminal 2
yellow and red from 4 core both in terminal 1
all blues or blacks in terminal 5
all earths in terminal 4
red from 3 core in terminal 6
red from fused spur in terminal 3
and a link put between 3 and 6
what I`m trying to establish is, how is the mid port valve operating via the cylander stat, or isn`t it, I would idealy like to use a programmer that would work the rads and hot water separately. I have purchased the drayton LP522, will it work with the present wiring, there is a 3 port mid valve, and cylander stat in operation, also a room stat.
kind regards
John Lockett
