TMV Temperature Testing explained
Temperature testing is carried out with calibrated equipment and issued as a signed, dated schedule per outlet for auditors and inspectors.
- Calibrated thermometer readings: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
- Mixed outlet temperature: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
- Hot and cold supply temperatures: Electrical tests and isolation belong to a qualified person; repeated resetting should not replace fault investigation.
- Signed test sheet: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.

TMV Temperature Testing: scope, checks and next steps
Temperature testing is carried out with calibrated equipment and issued as a signed, dated schedule per outlet for auditors and inspectors.
What the reported symptom tells us
outlet temperature checks needed for an audit or inspection. Record when this occurs, what changed beforehand and whether other equipment is affected. These observations narrow the investigation; they do not prove which part has failed.
