Thermostatic valve and floor heating
Hello,
I`m using the room thermostat at this moment with my floor heating.
in the near future i want to add the thermostatic valves to the rooms upstairs so these can be heated seperatly as well.
in most cases the rooms upstairs now are colder than the living room. so with the valves they can measure the temperature and tell my boiler to go to work to heat things up. what i don`t want is that they heat up the living room as well so i want to close this seperatly and controlled by the room thermostat.
my floorheating manifold is in the utility room. can i put a thermostatic valve on the supply pipe which is controlled by the room thermostat? so the boiler can heat up the upstairs rooms without sending the hot water to the floor heating?
greetings Frans,

Netatmo Valves as an actuator won't work well since they will take the temperature measurements wherever the splitter will be located and not in the room.
There are installations where the single valves are located in every room with an analog thermostat-head. But electric systems with a central splitter are more common these days.
A second Thermostat will work and wiring the actuator to the Thermostat while the second Relais (each Thermostat comes with and needs its own Relais) has to be wired in parallel with the existing one to the boiler, that will work as well. Relais and Thermostat always switch ON/OFF both at the same time.
However I think the software won't handle this type of installation as a single home rather than two homes (one per Thermostat) and therefore 2 schedules have to be programmed.
At least it was like that in the past. Since this season I don't have any Netatmo Energy products in use anymore, so I can't say for sure, sorry.
But both Thermostats (the one with the Radiator Valves and the one with the floor heating attached) should be able to start the boiler that way.
And what if I move the Thermostat from my living room (this room also has two valves on each of the radiators) to my new extension. Than all the smart radiators in the house can request heat whenever needed. I make the zone with underfloorheating my main room that requests with the thermostat and connects to the relay. Then I wire the Thermostat in this room with the Actuators on the floorheating. This way when the thermostats requests heat in the extension it triggers the actuators to open.
Do you know if the thermostat can be wired to multiple actuators at the same time?
If I remember correctly, the Thermostat can switch up to 4 Amps. It‘s listed in the technical specs somewhere.
It is true that the Thermostat can be placed in a room together with Valves and act as a central temperature sensor and control panel for that room while the Relais is wired to the boiler in „COMFORT priority“ mode.

However I don‘t know if this works with no Valves in the same (app)room or if the Thermostat‘s switch actually operates different than the Relais‘ or at all in this mode.
You will have to try that yourself, sorry.
EDIT: specs say:
Switching power
Switching current
Switching voltage
