Ambient temperature sets the starting point for how hard the freezer must work to reject heat.
Practical impacts in busy Irish kitchens:
Higher room temperature and nearby heat sources (ovens, hot pass, dishwasher exhaust) reduce cooling capacity, so the cabinet may take much longer to reach setpoint or may not hold it during peak service.
Poor ventilation around the condenser traps hot air, effectively raising the “ambient” the freezer is breathing, even if the room itself is not extreme.
More humidity and door openings add extra heat and moisture load, increasing frost and recovery time.
If performance issues appear mainly during hot shifts and improve overnight, that pattern strongly suggests an ambient heat or ventilation constraint rather than a control fault.

FAQ
What does a high-temperature alarm or flashing temperature display mean?
A high-temperature alarm or a flashing temperature display usually means the controller is reading cabinet air temperature above its alarm threshold for long enough to trigger an alert. After start-up, this can be normal
