Hi
I am planning on installing two UFH mats,
One 9m2 the other 6m2, i have the one controller, (living room / dining room)
Is it ok to put both mats into the one controller?
 
No not an electrician by trade
The mats are 150w

The controller says
Voltage : AC230V
Setting range: 5℃~50℃
Limitation range: 4℃-99℃
Switch differential: 0.5℃
Protective housing: IP20
Housing material: anti-flammable PC
Floor sensor: rubber-thermoplastic NTC sensor,cable length is 3m
CE Certificated
 
If you're not an electrician and clearly you are struggling with this I'd strongly advise you get an electrician to connect this for you.

Theres no way each mat is 150w. They are different sizes for a start.

If there was a total load of 300w over an area of 15m2 it wouldn't be getting very warm at all.

Like I said before, get someone who knows what they are doing. I suspect I'm banging my head against a brick wall here though.

Or a nice warm floor perhaps :tearsofjoy:

He means 150w per metre
 
so total load will be 2250watts. most stats should handle this, but should only fit 1 floor sensor, . if 2 are fitted, they will conflict.
 
Ok so i have pulled the wire i had in my wall from my last thermostat,
(replaced with a nest 12v)

I am going to wire up my new thermostat but the wires are not what i expected to be ( see photo)

So to wire up the thermostat what wires go where?
Grey (N)
Brown (L)
Black (switched live)
Green (E)

Thanks

Mark, you can not use a 12v stat to switch 230v. You are giving me the impression that you do not have the electrical competence/understanding so please don't proceed further others on here maybe not so diplomatic.
 
the new thermostat i have is 230v,

The wires that came out of my old stat, the electrician (who fitted my nest) says is 230v so i used a 12v to power my nest for my radiators and heating the water,

I planned to use the wires that came out of my old stat ( see photo)
to power my new UFH stat,
