MTN6214-03xx window function

[PiotrJakubczyk]

Hello 

I have read application description for MTN6214-03 ( doc P6212_562_00_1817_10_EN ) and window functionality (turn off heating cooling when window is open) is described very generally using "Locking object". Can someone explain how to configure MTN6214-03 to have window (energy holdoff) functionality and what additional device will be needed (binary input MTN644492 ?)  

Anything that can be interpreted as similar functionality is in Control general/Termination of comfort extension via objects

and then use "Comfort extension input" in group address with  switch object from Binary input?

You should use object 45 - Frost/Heat protection

See attached expert training document on page 18

Hi!
Erwin is right. You should use the frost heat protection function.
Attached an older picture but still valid.

And YES you can use MTN644492 for it.

Thanks Erwin! 

Can i switch on "bell icon" when window is open? Or user should interpret lack of heating/cooling icon as opened window?

Hi Piotr,

in general it is up to you or your customer requirements.
Of course you can use the "Bell function / Symbol" for it.
