3 days ago I changed my central heating settings via UP1L programmer to "Hot water only" from "central Heating". Since then my danfoss pump has run continuously even when programmer does not call for Hot water or central heating.
The only way to stop pump is to switch off main electric switch to central heating.
Do you think I need a new programmer or is their another problem?
System worked up to three days ago and is about 8 years old.
