I would like to turn the underfloor heating off when a max temp reached and/or over night incl. controlling the underfloor heating pump. Somehow it feels that max two Thermostats would make the most sense, and to turn the existing pump for the underfloor heating with those on or off in addition. JohnMo, what do you mean by " single thermostat controlling pump". At the moment I have a grundfos pump. If they are using a switched live configuration then it'll be fine but if they are using a resistance based method you'll need to replace the wiring centre - which is what I had to do. At the moment, even when I turn of the pump and the heating is on, it gets hot water pumped through by the main boiler, of course less than with the pump on, but I would like to have the freedom to turn the underfloor complete off when possible.

Another point is that tado wireless receiver has also the connection for a relay. I was wondering if the wireless receiver could be connected via eBus to the heating system and via the relay wires to the actuator. (If yes, then I could use a tado wireless temperature sensor in the living room and get rid of the wires. (But I do not know how to configure the wireless receiver to control both eBus and relay.) I wonder if I need a wiring to the boiler in the loft by using the Tado wired smart thermostat downstairs, and the wireless smmart thermostat next to the boiler? I plan to connect the wires of the tado thermostat to a relay which could trigger the on/off of the actuator. Hopefully the tado thermostat will also "inform" (via the wireless communication) the central heating to start.

As far as I understand, the wireless one would fire up the boiler when necessary, but it can not control that for the UFH pump will go on, right? So with all other Radiators ( beside the Bathroom ) tado valves fitted it is kinda useless, or I use it in the Bathroom. Or do I understand this wrong? Somehow it feels that max two Thermostats would make the most sense, and to turn the existing pump for the underfloor heating with those on or off in addition. ProDave Do I get it right that you recommend the a motorised valve to avoid the problem which I have at the moment, which is that even when I turn of the pump and the heating is on, it gets hot water pumped through by the main boiler, of course less than with the pump on. I bought the wireless extension kit and I wired the wireless receiver directly to the heating system and it communicates wireless with the smart thermostats.

Modellkompatibilität: 2 Watt, 230V - 2 Watt, HC-12a, 230 Volt - 2 Watt, 2 W, A+++ - D, 230V - 1 Watt, Keine For example a heatmiser 4 zone with 4 actuators installed. Could I get each 2 Actuators controlled by 1 Tado wired smart Thermostat,I wonder how we can control it best via Tado and how many Tado wired Thermostats are useful, as I could just install them quite close together ( like around the corner with 1 m each from the corner ), maybe with new wiring one direct in the kitchen area and one in the Livingroom/dining room area I know you wrote that you don't know Tado, So I wonder in general if Tado can control the pump I have ( plus possible a new motorized valve ) I would like that Tado can communicate with the boiler when it needs heat, just like the radiator valves. We have a new underfloor system in an open space Livingroom / Kitchen in a L-shape. The builder put 2 zones in the kitchen are ( one end of the imaginable L-shape ), one zone in the middle where the main Livingroom area is and one zone at the other end of the L-Shape area, where the dining area is, plus it goes over in a nearby small utility / toilet. ( see image ) Our Worcester Bosh boiler is in the loft and the underfloor downstairs. Do I need wiring up to the boiler to control them, even when I use the tado wireless smart thermostat? So currently I already own the Tado Wireless Starter Kit V3+ which comes with the Boiler control and one wireless Thermostat.

Not sure why you'd want wireless if you have wired thermostats - generally the wireless route is only because you have not got wiring in place - and will be more expensive.

( see image ) Note: Wireless UFH systems are not supported - if you had one of those you have to replace the control centre. You have mentioned that : you should have the stat control the valve and then the valve control the pump and the boiler. That means the boiler fires independently if UFH or Rads request heat.

For example a heatmiser 4 zone with 4 actuators installed. Could I get each 2 Actuators controlled by 1 Tado wired smart Thermostat, At the moment we use upstairs radiators tado valves, and we have bought but not installed yet a Tado Starter Kit Wireless Smart Thermostat, to control the Worcester Bosh boiler, and one wired Smart Thermostat for the underfloor heating. PeterW, the Wunda self balancing actuators look very interesting. I will have this in mind, should I still need actuators. Thank you.

You've not said how many zones, but if you desperately wanted wireless thermostats (which makes no sense if you have wiring in place) then I think some people have managed it by fitting wired thermostats to the valves and then wireless temp sensors in the room it controls. That gets quite expensive esp if you have a lot of zones. At the moment I understand that you suggest using the wired Tado Thermostat to control all 4 valves ( actuators ) = would you recommend any special and would I need a controller box for this?

When possible I would appreciate a wiring explanation too please, and what you would recommend to install.
