Stage 3

Thermal Audit

A readable summary of zone comfort, heating/cooling effectiveness, simultaneous heating and cooling, valve hunting, history coverage, and data quality. The CSV still exists for the spreadsheet goblins.

HIGH
14

Equipment requiring immediate review.

MEDIUM
4

Equipment worth reviewing before it becomes theatre.

AVG SCORE
29.17

Average thermal summary score. Higher is better.

DATA QUALITY
18

Equipment with stale, missing, partial, or fallback-dependent data.

High-priority thermal findings detected

Review the top action cards first. These usually point to simultaneous heating/cooling, ineffective heating or cooling, stale histories, or missing usable data.

How to read this report

Thermal score starts at 100 and is reduced by priority, data quality issues, comfort failures, valve conflicts, and ineffective heating or cooling. Readiness tells you whether enough mapped histories exist to run useful checks.

Fallback setpoint means the audit used the configured fallback zone setpoint because no usable zone setpoint history was available. Useful, but not divine truth.

Recommendation: Zone temperature was above setpoint plus deadband for a meaningful period. Check load, cooling availability, valve operation, air delivery, and setpoint assumptions. Zone temperature was below setpoint minus deadband for a meaningful period. Check heating operation, excessive cooling, schedules, and setpoint assumptions. Heating valve was highly open while supply air was not warm. Check hot water availability, valve operation, coil performance, sensor calibration, and control sequencing. Heating valve was highly open while the zone remained below setpoint. Check heating capacity, airflow, hot water availability, valve authority, coil condition, sensor calibration, and whether the fallback setpoint is appropriate. Heating valve movement suggests possible hunting or unstable control. Review PID tuning, sensor noise, actuator behaviour, deadbands, and control loop sequencing.
