Hi, in my house, the black indicator goes up and down as set by the thermostat. But the heater in one room is always on. I want to remove it to check the pin inside but the screw is completely rusted. How can I fix this problem?

Drilling the screw could be an option. But after this you would probably need new actuator.

Hi, I have water underfloor heating system which actuator do I need to use NC or NO and why?

For underfloor it is more common to use NC. In case electricity fails or automatics - your floor will be secured. And as concrete holds heat you will not get frozen for a cuite long time to fix the problem.

can it be comnected to 220V directly ?

Yes. 230V actuators can be connected to 220-230V directly.

I think those thermal actuators are very stupid. If you have 5 groups that are active for 50% of the time (for example with a heatpumps) you use 5 x 2W x 12 hrs per day. There are battery powered thermostatic controls for radiators, why hasn’t this technique been improved for those actuators….

Thermal actuators are reliable, may last 10-30 years, has no noise. 5 x 2W x 12h x 30days= 3,6 kWh - not a lot.

I have battery operated TRVs at the moment and looking at these wired versions as a good alternative. The smart TRVs are not strong enough long term, requires batteries and have "smart crap" in them making them not do what I want.

Waste talk all the way not necessary
