Danfoss 088H3220 Actuator, White

Product Information

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 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?

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.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. 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.

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. I would like to turn the underfloor heating off when a max temp reached and/or over night incl. controlling the underfloor heating pump.When possible I would appreciate a wiring explanation too please, and what you would recommend to install. 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.)
