Danfoss LC13 not turning heat down

#1

Made my first piston.

Using Piston to regulate temperature in bedroom. Using Danfoss LC13 valve.

The piston initiates a rise in temperature as it should - but it doesn´t turn heat down as it should.

What mistake am I making?

Could it be because of your restrictions of the heat down set point? Ie. Home, away, night? Try removing that and see what happens. That is the only difference I see in your two statements.

Tried to remove it - still doesn’t work :frowning: only setting temperature up works - do have to turn it down manually.
