i am tryint to program these heaters with this device x2d pw4 -- i set all zones to full on (or at least i think that is what i am doing because i dont have a manual and the menues are quite cryptic) but anyway i think i programmed Program 1 -- but i see no difference. The heaters still only turn ON when i switch both switches on the wall and only turn OFF from the switches too -- so what is the purpose of the switches and how do i know when the program is running --- this is very confusing
