Hi guys just in the process of wiring up a 3 zone Drayton jb with 3 zone wireless heating controls.
My question is as it stands at the moment which ever zone is on ie rads, hot water and underfloor heating the pump on the underfloor heating will start running, now I’ve not done a lot with domestic systems as I’m a industrial sparks this is for my own house I’m renovating.
So what are you guys doing letting it run or is there some kind of relay mod I can do so the pump only pumps with the underfloor heating zone?
Any advice would be great thanks Underfloor heating pump DE142786-A6DB-4E6E-8A4F-F1D59AA37638 - EletriciansForums.net
 
Without knowing how your system is set up it is difficult to advise on the best solution to solve the problem
Does each zone have it's own zone valve and is each zone separately pumped or is it a single pump for the other zones controlled by the boiler or zone valves

Can you post up a diagram of how it is currently wired it may help to identify a simple solution

hi bottom set up thanks
 
And the rest of the answer is........

Does the main pump have to run with the UFH pump for heat to the UFH?, are you using a low loss header?, a layout sketch of how the system is plumbed (boiler, pumps, valves etc )would help as you are looking at something beyond a standard wiring diagram.
I'm assuming the boiler has / needs a pump overrun to dispate heat when the system shuts down
 
Funny enough I've had to look at a job today, the customer wants me to remove all his Heatmiser RF stats and install Nest everywhere. I'm going to have to remove the relay box as their is no trigger input for each zone.( RF trigger only).

There's only 2 zones on the UFH and the customer is happy to combine them,
I'm not happy triggering the UFH pump from the brown of the valve so I'll pop in a 8 pin octagonal relay.

Sorry about the dodgy diagram.
