Instructions for these?

Anyone know where i can find the instruction manual for these thermostats?
I know they have Room and Floor modes, but that's about it. My apartment has underfloor heating and these are the controls, yet there are no instructions and the landlord has no idea either since theye were there when he bought the house.
Text says El-Installasjon as. No other visible model or info. Not going to remove the bezel to check.
