wiring

[fitz1]

one boiler , 3 clocks , 3 pumps, 3 2port valves. one pump for dhw and two pumps for two heating levels. how can this be wired so each will fire boiler independantly

Why three clocks on 2 zones?
Or is it three single chanels?

Basically you wire each clock to each pump to each valve so they work from each clock.
If you/customer can afford it get 3 honeywell smartfit outfits mate.

existing install in a pub where someone has muddled all the wiring up.just trying to get my head around it.what stops the boiler live from linking the other pumps when one is on. there is 1 cyl stat and 2 room stats.

baxipoti do you use the partridge as a crbon monoxide detector.

im not wiring the clocks to the pumps , im wiring the clocks to the stats and then to the pumps and valves.
