FAQ's of Temperature, humidity, and co2 display and controller for cold storage applications:

Q: How do I install the Temperature, Humidity, and CO2 Display & Controller in a cold storage room?

A: The device comes with a wall-mount bracket and easy installation kit. Simply select an accessible, central wall location inside or outside the cold storage room, mount the display and sensor panels, connect the power supply (110-240V AC), and wiring for relay/analog outputs. The user manual provides clear installation instructions.

Q: What is the process for calibrating the sensors and setting alarm limits?

A: Sensors are pre-calibrated at the factory for high accuracy, but you can perform field calibration using reference standards for temperature, humidity, and CO2. Alarm thresholds for high/low values are programmable via the microprocessor controller using the setup menu or keypad interface.

Q: When will the alarm outputs be triggered, and how can I customize them?

A: Alarm relay outputs activate whenever temperature, humidity, or CO2 exceed set high or low thresholds. You can program these setpoints based on your storage requirements through the controller interface, ensuring rapid response to any deviations.

Q: Where is the best location to mount the sensors in a cold storage facility?

A: Mount the sensors where air circulation is uniform and away from direct airflow from HVAC vents or doors. Avoid corners and spots prone to condensation for optimal sensor performance and accurate environmental monitoring.

Q: What are the main benefits of using this controller in cold storage applications?

A: This system provides continuous, precise monitoring and control of environmental parameters, safeguarding sensitive goods by preventing spoilage and ensuring regulatory compliance. Automated controls and programmable alarms optimize energy use and reduce manual monitoring.

Q: How often does the display update its readings?

A: The display panel updates temperature, humidity, and CO2 values every one second, ensuring real-time visibility and prompt detection of fluctuations.
