UFH-no controls fitted

[Ted808]

Went to job last week, cust has had builder in, who has installed UFH- only one circuit, to the kitchen/dinner extension.
The pump is on a 3 pin, plugged in, on 24/7.

So my question is what sort of controls can I add.?
I was thinking of using a Danfoss RF+3 digistat (same as what they have), but wonder if would connect to the other RF.
( roomstat-timer - dial on the boiler.) as it's in the basement and would it work ?
PUMP and Actuator activated by second RF placed in the kitchen.
The UFH would be only temp controlled and off when the boiler timer is off, is this acceptable? I'm just not sure! :001_9898:

?? Is there a manifold?
is there a tmv on the manifold?

Heatmiser, best UFH controls ... Programmable room stat and wiring centre for the actuators on the manifold

Really just a single loop? bet he laid it serpentine as well, lazy ^&^&%"££$$"£ ....

yep worcester there's a manifold for a single loop and it is probably laid serpentine-can't see it floor is screed'd. I'll check out your links, but will my suggestion work?

The problem is are there any actuators of the UFH manifold? photo needed of the manifold please..

There's one actuator, and the pump, but it's not near the boiler so no cable from boiler.
Could I wire in the unit onto the ring mains and take off the pump and actuator=which will respond to the roomstat? It's not ideal but i'm not an electrician and i don't want to start running a cable from the boiler. I mean there is a RS for the radiators but i don't think i want to twin the rad's with the UFH as i want them to work independently. If this makes sense? It's a JG manifold, two circuits, one capped off.
