my night heater had a power interuption and has reset itself back to default settings when you press the (flame) start button now it runs for 120 mins then turns off how do you get the thing to run constant ie if you left it running friday it would still be running come monday morning i no its something easy as i did it when i first got it but cant remember what i did its a webasto ( i think ) found in alot of the older trucks
if its got a button with a P on it thats the program button. from there you can set the running time it stays on for and also how many
times it comes on during a 24 hr period. if its not got a program button try turning the temp control down and it will only come on at a certain temp
Depends which night heater it is lee " what truck is it in" there is a black box out there what you buy to plug and play and it removes the hour run time and just works all the time until turned off/on, with the control unit

i thought you took yours out as they use diesal 
Im pretty sure its a webasto its in the man its the same as the iveco ive got and im sure there in dafs aswell small black flush fit box, clock, rotary temp, 5 buttons (from the left) clock , p programme button , flame start button , arrrow left , arrow right , it works but only runs for 120 mins even when you programme it i can up the time using the arrow buttons but only up to 120 mins max it would run constant until i disconnected it last week now its bugging me same problem as when i first got it its got to be something simple as i managed to sort it
its the 7 day control planner, see if you can swap it over with someone elses to try , about 180 quid, door hinge 100 quid, welding behind door hinge 60, piece of mind when you own a volvo…priceless…only joking,…marmite lorrys !
Seems a bit pointless to leave it running all weekend?
