## Article body

This comprehensive guide explains the technical information you need for data center cooling control — from project design through commissioning. It includes practical recommendations, checklists, and FAQs based on Heatemp Controls engineering and field experience.

## Hot aisle / cold aisle design

Airflow management directly affects PUE in data centers. Containment barriers improve sensor reading consistency.

Cold aisle temperature is the primary control parameter for IT equipment reliability.

## Sensor network topology

Analog and digital sensors integrate into central BMS or DCIM platforms.

Dual sensors on critical racks are recommended for redundant readings.

## Alarm and event management

Tiered alarms: define warning, critical, and disaster thresholds.

NOC integration via SNMP, Modbus, or BACnet should be provided.

## Capacity planning

Trend analysis alerts before cooling capacity is exhausted.

Update the sensor map when new racks are added.

## Maintenance and calibration

Annual calibration and sensor drift checks are part of SLA requirements.

Clean sensor surfaces periodically in dusty environments.

Correct product selection and integration directly affect your project's long-term reliability and energy efficiency. Contact the Heatemp Controls engineering team for project-specific support on data center cooling control.

## FAQ

### What is the target rack inlet temperature?

ASHRAE A1 class typically targets 18–27°C; can be narrowed per project SLA.

### How many sensor points are enough?

At least one inlet and one outlet per rack row; 3–5 m grid recommended in large halls.

### How should alarm delay be set?

Use 30–60 s delay to filter spikes; instant notification on critical threshold breach.
