press the two buttons on the right and hold them untill (I think) 'HS' appears, release the buttons and use the up or down arrow on the left hand side, you are looking for 'd' or 'd1', press set and use the up or down arrow to select the diff you want say 2 or 3 then press set again, once you have changed the diff and 'd' or 'd1' is showing press and hold the prg button until the display shows the temp, cheers

Thanks Paul.
Just managed to get manual.
All 176 pages. "F*** me" for a temp controller.
Out of the million codes, I think its called TR11.
Or just looking at the book, there are so many variables that could be included when the manufacturer set it up. Dynamic, off set, compensating, PID bla bla bla.
Would you not think that the equipment manufactures would send out a report showing what they have set these electronic gadget to. (not just relying on the defaults from the gadget manufacture)
Mad is mad
