When to adjust temperature setpoints

Overview

Adjust temperature setpoints only when there is a clear, ongoing issue, such as:

Products too warm or too cold
Frequent temperature alarms
Excessive energy use

We normally recommend start with the default settings that come with the SCS Controller and then make small, controlled changes only when needed. It is also important to monitor results to ensure the setpoint adjustment improves performance without creating new issues for the cooler.

Common scenarios that may mean you need to change the setpoint

Issue	Cause
Products too warm High temperatures or frequent alarms	Setpoint may be too high
Products too cold / freezing Ice or frozen goods	Setpoint may be too low
Frequent alarms Repeated alerts during normal operation	Setpoint and alarm thresholds may be too close
High energy usage Unit runs frequently	Setpoint may be lower than required

When NOT to adjust

Do not adjust if:

The issue is intermittent
The system has not stabilised after install

The cause may be:

Sensor placement
Door usage
Ambient conditions
Hardware faults

What you can adjust

Setpoint ("target temperature")
Temperature range
Alarm thresholds ("when alerts trigger")

Adjust setpoint in small steps using Field app and monitor results.

Comparison: What happens when you make an adjustment?

Adjustment	What improves	Trade-offs to consider
Lower setpoint (colder)	Better cooling performance Reduced risk of warm products	Higher energy use More compressor run time Risk of freezing
Raise setpoint (warmer)	Lower energy use Less compressor activity	Higher risk of warm products Possible temperature excursions
Tighten temperature range	More stable temperature Fewer fluctuations	More frequent cycling Increased wear and energy use
Widen temperature range	Less cycling Lower energy use	Greater temperature variation

Specific guidance by Role type

Role	Suggested actions
Service Technician	Adjust setpoints when: The issue is consistent (not one-off) Hardware and installation causes are ruled out Good practice: Change gradually Record original values Verify results before further changes
Hardware Installer	Use default setpoints at install. Do not adjust to compensate for: Poor airflow Incorrect installation
Site Manager / Fleet Manager	Setpoint changes are normally made by a service technician but talk to your Customer Success Manager if you are interested in remote features that can be managed by connection to the AoFrio iQ platform. Ask your service team to review a cooler's setpoint temperature if: Products are consistently out of range Alarms affect operations Energy use seems unusually high
