A wall sensor is above a copier and receives afternoon sun. How should the control-location problem be resolved?
- ACover it with insulation
- Relocate it to a representative location
- CCalibrate it only at night for the described HVAC equipment and measured operating conditions
- DIncrease equipment tonnage
Why B is correct
The best answer is: Relocate it to a representative location. Local heat and solar gain bias sensed temperature and cause poor comfort and cycling. The sensor must represent the controlled zone rather than an abnormal microclimate. The transferred operating condition requires the same design, installation, diagnostic, or safety principle in a different HVAC context. The other choices skip a prerequisite, conflict with the listed procedure, or treat a symptom without controlling its cause.
