When I search for answers, your videos always show up are are the most helpful. Thank you for making these! I have a Danfoss Icon system but whoever installed it installed a Giacomini distributor and actuators. I am replacing a broken Giacomini with a Danfoss TWA-K. I believe this is a compatible connection. Is there anything I need to think about?
Hmm, TWA-K will not fit for Giacomini, unless there is an adaptor mounted. If you have Giacomini manifold and Giacomini actuators, where should be no additional adaptor. You can mount Danfoss acctuator ABN-FBH NC 230V 193B2147 (for Icon 230V, or Icon2 230V) + connector 193B2017 OR ABN-FBH NC 24V 193B2148 (for Icon 24V, or Icon2 24V) + same connector 193B2017
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.
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?
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….
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.

@@heatingsolutions123 Good to know. Plan to replace it all with Danfoss. Thanks for the quick response 👍 👌
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.
I have a Danfoss manifold with my UFH, i need 18 actuators, which type do i need for this type manifold.
@@stephenhunter956 for Danfoss manifold fits TWA-A actuator. Usually used NC type, 24 or 230V depends on controls

Drilling the screw could be an option. But after this you would probably need new actuator.
can it be comnected to 220V directly ?
Yes. 230V actuators can be connected to 220-230V directly.

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.

Waste talk all the way not necessary
Thank you for your feedback.
