hi, i have a salus digital room thermostat, it has just been fitted today and i am finding the instructions a bit confusing, i think i have set the week days , but it becomes a bit confusing when trying to set the weekend, it only seems to go on the 5 and 2 day setting, how would i get it onto the 7 day setting, can someone please email me with the instructions in plain english, not total gibberish, i am by no ways thick, but this has just done my head in please help
