Thanks guys really appreciate your comments:
Its an office block, tried shut off valve doesnt appear to sink so re=level. As I have said its level on arrival after fault. Cannot be sure whether anyone is in building over weekend I am told there shouldnt be but this is from office staff not maintenance staff
I dont know at this point what is causing the fault to appear, the manual just says 06 - re-level fault, it doesnt sat whether failed to relevel or relevelled several times etc. I was hoping someone might know who read this.
I am happy to keep listening, you guys are in us this is in uk just to let you know.
many thanks
