Energy optimisation starts with good data.
The AccQ unit is a standards-certified, lab-grade, high-accuracy modular temperature sensor and control node for commercial HVAC and datacentre applications. Alongside highly accurate measurement, it computes on the edge and integrates with external optimisation algorithms.
±0.02 °C*
Matched-pair ΔT tracking with calibrated thermistor pairs, CHW and CDW bands.
24 channels
Up to 24 channels of high-resolution water-temperature, 6 per module (12 matched ΔT pairs).
Auto re-calibration
AccQ recalibrates itself for each measurement cycle to ensure maximum accuracy.
*Anticipated accuracy, subject to final laboratory report.
Why AccQ
Start from measurements you can act on.
Meaningful optimisation require accurate data. Highly accurate measurements supplied to algorithms in real time allow a far greater level of optimisation than traditional PID control. AccQ provides lab-grade temperature data that supplies modern optimisation algorithms with measurements good enough to act on: understanding what is happening, as it happens, is what makes a dynamic environmental control system efficient.
Certified accuracy
Each unit and probe is certified in the lab, pair-matched for ΔT, and the chain lives in the cloud, straight from us for full traceability.
Plays well with others
Sit alongside the BMS you already have. Open protocols, no licensing lock-in, no downtime for upgrading.
Read howA second loop for optimisation
The same unit that answers the BMS also feeds parallel data streams. Your measurements, your stream, your algorithms.
