What does RTU-07 mean?

On days cool enough that mechanical cooling should barely run, the compressor runs most of the time.

Why does it matter?

Points at low charge, a failed economizer, a setpoint problem, or a space sensor in the sun.

What should you do?

Verify economizer operation and changeover, refrigerant charge, and the zone sensor location/setpoint.
