Building example
Plant room and AHU, valve by valve.
Polyvalent heat pump, storage tanks, three-way valves and an air handling unit with heat recovery wheel, coils, humidifier and inverter-driven fans. Here you see control loops, sequences, energy and forecast with simulated data; one second is one minute.
With AI machine learning forecasts heating and cooling demand, optimises sequences and flags degrading valves, filters and heat recovery in good time.

Control loops · in the AHU controller, read by Link
Control runs in the AHU controller: the Suite reads the measured value, setpoint and output of every loop, stores and shows them. If a loop oscillates or stays saturated, you see it here.
Controls
- Airflow
- —
- Supply setpoint
- —
Sequence —
The controller runs the sequence; Studio triggers it from the time schedule or a button and logs every step.

In full heat recovery, the heat taken from the air by the cooling coil goes into the hot tank: reheat comes almost for free.

Devices in Link
- Polyvalent heat pump · Modbus TCP
- AHU controller · BACnet/IP
- Fan inverters (2) · Modbus TCP
- Energy meters (3) · Modbus TCP
- Room sensors · BACnet/IP
Link reads the controller, heat pump, inverters and meters and makes them available to Studio.
Anomalies · Datathesys Cloud
—
Studio sends the data to Datathesys Cloud, which compares days and flags unusual behaviour.
Weather forecast —
Expected behaviour of the plant room
Time schedule, control loops and heat pump applied to the forecast weather.
What the Building vertical does
AHU and heat pump equipment models: tags, pages and rules together. The second AHU is a copy of the first with a different address.
Control loops under watch: value, setpoint and output stored, with an alert when a loop oscillates or stays saturated.
Sequences and time schedules: start and stop triggered from Studio, every step logged.
Energy: kWh per machine, measured COP and EER, energy recovered by the wheel and the polyvalent unit.
Condition-based maintenance: filters, running hours and defrosts, with the expected date of the next replacement.
BACnet/IP and Modbus TCP in Link, anomaly detection with Datathesys Cloud and Operator from anywhere.
