Direct input/Step +/-

[Amelie]

Hello,

I'm new to the forum and a new user of the logic machine, so forgive me if I have a stupid question.  

I try to make a visualization to control te heating of my home. For the adjustement of the temperature, I want to use a 'Direct input/Step +/-'. I have to questions: about the use of it:

• Can I adjust the size of the object. It is quiet large in comparison of the rest of the visualization..
  
• Can I change the step so I can change the temperature with 0,5°?
  

Thank in advance,

Amelie
