Outdoor applications: Only possible where (sea) water, snow, ice, sunlight or aggressive gases cannot interfere directly with the device and it can be guaranteed that the ambient conditions remain at all times within the thresholds according to the data sheet. Only authorized specialists may carry out installation. All applicable legal or institutional installation regulations must be complied during installation. The device contains electrical and electronic components and must not be disposed of as household refuse. All locally valid regulations and requirements must be observed.22PE-5U.. • en-us • 2022-02-01 • Subject to change4 / 9 The thermal energy meter consists of a volume measuring section, evaluation electronics and two temperature sensors. One temperature sensor is integrated in flow sensor, the other temperature sensor is installed as an external sensor. The device determines the thermal energy supplied to heat exchange or coil from the volumetric flow and the temperature difference between supply and return flow. The thermal energy meter can be operated as a heat meter, cooling meter or heat/cooling meter. In addition, it can be installed either in the return or in the supply of the system. The corresponding application must be set via NFC when activated with the Belimo Assistant App. A calibration certificate is available in the Belimo Cloud for each thermal energy meter. If required, this can be downloaded as a PDF with the Belimo Assistant App or via the Belimo Cloud frontend. The energy meter can be programmed as a combined heat/cooling meter via NFC and the Belimo Assistant App. The thermal energy meter measures the current flow rate every 0.1 s in mains operation. The thermal energy meter calculates the current thermal power based on the current flow rate and the measured temperature difference. The energy consumption data can be read out as follows: - Bus - Cloud API - Belimo Cloud Account of the device owner - Belimo Assistant App - Integrated web server The "Terms of Use for Belimo Cloud Services" in their currently valid version apply to the use of cloud services. Note: The connection to the Belimo Cloud is available. Activation takes place via web server or the Belimo Assistant App. If necessary, the thermal energy meter can be supplied with power via the Ethernet cable. This function can be enabled via the Belimo Assistant App or the web server. DC 24 V (max. 8 W) is available at wires 1 and 2 for power supply of external devices (e.g. actuator or active sensor). Caution: PoE may only be enabled if an external device is connected to wires 1 and 2 or if wires 1 and 2 are insulated! Once commissioning has been completed, a commissioning report is available via the web server or the Belimo Assistant App, in which all settings and basic data are presented in a clear and structured manner. The commissioning report can be saved as a pdf file.22PE-5U.. • en-us • 2022-02-01 • Subject to change5 / 9 Measuring accuracy for water: ±(2 + 0,02 qp/q) % of the measured value q At a temperature range of 5...120°C.

Its dimensions should be at least 5x DN. a) Recommended mounting positions b) Prohibited mounting position due to the danger of air accumulation c) Installation immediately after valves is prohibited. Exception: If it is a shut-off valve without constriction and it is 100% open d) Installation on the suction side of a pump is prohibited The water quality requirements specified in VDI 2035 must be adhered to. Thermal energy meter are maintenance-free. Before any service work on the thermal energy meter is carried out, it is essential to isolate the thermal energy meter from the power supply (by unplugging the electrical cables if necessary). Any pumps in the part of the piping system concerned must also be switched off and the appropriate slide valves closed (allow all components to cool down first if necessary and always reduce the system pressure to ambient pressure level). The system must not be returned to service until the thermal energy meter has been correctly reassembled in accordance with the instructions and the pipeline has been refilled by professionally trained personnel. The direction of flow, specified by an arrow on the housing, is to be complied with, since otherwise the flow rate will be measured incorrectly. To avoid cavitation, the system pressure at the outlet of the thermal energy meter must be a minimum of 14.5 psi [1.0 bar] at qs (highest flow) and temperatures up to 195°F [90°C]. At a temperature of 250°F [120°C] the system pressure at the outlet of the thermal energy meter must be at least 36.3 psi [2.5 bar]. Before installing the thermal energy meter, the circuit must be thoroughly rinsed to remove impurities.22PE-5U.. • en-us • 2022-02-01 • Subject to change8 / 9 The energy meter must not be subjected to excessive stress caused by pipes or fittings.

The wiring of the line for BACnet MS/TP / Modbus RTU is to be carried out in accordance with applicable RS485 regulations. Modbus / BACnet: Supply and communication are not galvanically isolated. Connect earth signal of the devices with one another. Sensor connection: An additional sensor can optionally be connected to the thermal energy meter. This can be a passive resistance sensor Pt1000, Ni1000, NTC10k (10k2), an active sensor with output DC 0...10 V or a switching contact. Thus the analogue signal of the sensor can be easily digitised with the thermal energy meter and transferred to the corresponding bus system. Analog output: An analog output is available on the thermal energy meter. This can be selected as DC 0...10 V, DC 0.5...10 V or DC 2...10 V. For example, the flow rate or the temperature of the temperature sensor T1 / T2 can be output as an analog value.
