Additional heating zone

Former Community Member
Former Community Member
So 


I’ve to add a new zone into an existing heating system.


which currently has a 3 channel programmer

- Hot water

- House heating

- UFH


now I was gonna put a new 4 channel programmer in with a Timeguard TRT037N, wireless stat for the new zone


Am I right that to make this work, I’ll take a permanent Live & Neutral to my new receiver, also take a Channel Live and put into the Common terminal on the receiver with the outgoing onto the brown of my valve?

    The TRT037N appears to be a programmable thermostat - so why the need for an extra channel from a programmer?


    What's the motorized valve arrangements? I'm guessing a simple 2-port spring return for the new zone (and similar for the existing zones) - but there are other possibilities that would make things rather different. (I have a long dislike of 3-port valves but some plumbers seem to like them).


    I guess you'd also need the microswitch output from the valve to trigger the boiler (in parallel with all the other zones) - which you probably knew anyway, but as you hadn't mentioned it I thought it best to check.

    Yes it is only a 2 port valve.


    I have the orange from my valve connected with the rest of the boiler calls.


    as for the programmable stat & channel programmer. This is what the customer wanted and picked up themselves.

    Managed to power up and all was well.


    Now I have a fresh question, how would you tie in a 2 port valve into a UFH manifold?


    I looked at the one on the job which looked to be Salus KL06, and PL07 attachment.


    How would you make this work? 


    obviously Grey/Earth/Neutral on the port valve, brown would be connected where? Then orange is the boiler core so wouldn’t be needed in the manifold?


    The Live sent from the channel programmer would be connect to the incoming Live in the manifold?


    Tried to look for a wiring diagram online so I could see how it would tie in but with no luck.

    That’s interesting.

    All of the underfloor heating I’ve worked with the ufh wiring centre had connections to control the valve, but doesn’t seem to be on this one.

    Assuming you have non-programmable room stats then yes I think channel live to the wiring centre.

    I think I would then use the PL07 to control the valve so brown to the boiler on terminal, and then the valve to switch the boiler so orange to a separate core back to the boiler.

    Does seem a bit long winded though and not familiar with this system, so stand to be corrected...

    Yeah I found this very strange to.


    so going to the PL07 terminals, 1 and 2, brown from valve into 1, then connect orange into terminal 2 which goes back to the boiler?


    Then I assume terminals 3 & 4 are the pump? Live & Neutral?
