Hi
I am on the home straight to installing a complete ch system in my house.
The combi is a worcester bosch 28i and I have a Horstmann centaurstat 1 to
site in the lounge. Problem is although I found the ch a doddle to install
wiring is not my strong point. The Centaurstat has four connections 1)
Live (line) 2) Load (heat) 3)load (cool) and 40 Neutral (parking). The
combi has two sets of three connectors one for the room stat and one for
the programmer. The 3 for the roomstat are 1) RN (neutral) 2) RI (switched
live) 3) RL (live) and the 3 for the programmer are 1) CN (neutral) 2) CI
(switched live) 3)CL (live). So it appears that i will have 6 wires coming
from the combi to wire to 4 terminals on the centaurstat so it seems that
some trminals on the cetaurstat are shared. If anyone knows how to wire
this I would be very grateful for the info.
Regards
Nick


Ignore the 3 for the programmer, and ignore no.3 connection on the stat, and
then neutral to neutral, live to live and Load(heat) to RI (switched live)

Job done.
