Hi i have a dimplex duo heat 400n when i  turn on red lights come on go all the way to the top then stops at number 1,which says its a room temperature fault, we have no heat day or night any ideas what  i need to fix this.

 
At a guess it sounds like an electronic controller fault which will probably require a replacement circuit board or module.  I would contact Dimplex and ask who supports them in your area.
