Frequently Asked Questions
Why does my cold room temperature swing up and down?
Swing is usually a control issue — sensor drift, wrong differential, or a defrost cycle that runs too long. We calibrate the controller to a stable band.
Do you calibrate controllers for HACCP records?
Yes. We calibrate and document setpoints and sensor accuracy for food-safety and pharmaceutical compliance.
Can you set up temperature alarms?
Yes. We configure high/low alarm thresholds and dial-out or monitoring integration.
