Hi all,I have been asked to wire a central heating system (y Plan)... simple enough.. but...

Its one boiler, with one 3 port.... this is where it starts to get interesting...

2 controllers/programmers and two room stats.

Basically it one two separate accomodations fed by one boiler.

The central heating circuit out of the 3 port, will split into two zone valves, one for each place.

The HW obviously won't be zone, one cylinder stat

How would you guys suggest wiring this ( with 2 controllers and rooms stats), with the CH output from each controller also opening the zone valve

The pump will be connected to the boiler (to provide over run).

Just gotta watchout for conflicts between the controllers/valve ;)

O.

ps - I have my way of doing (don't ya love DIN rail boxes with twin relays) :)
Are these two accommodation sin the same physical building...

e.g. Upstairs & Downstairs or left & Right?

 
Yes, Miss Jones.
