Hi, I don't know anything about plumbing or DIY so please bare with me as
I try to explain my problem. I have a Mainmet EMS metering system for
heating & hot water, one of those prepaid card ones. Every other month it
stops working and an error on the machine says "Unit Requires Commissioning".
And every time this happens I have to call up to have it repaired, which takes
a few days. The engineers that come to repair it advise us on what to do to
avoid it happening again, we follow this advise, it happens again and the
next engineer tells us something different.
Does anyone know what this problem is?
Any advice?
Thank you.
