correction factor. In this case the PolluTherm is

not officially metrologically calibrated. These

installation and operation instructions specify how

to install and operate the integrator PolluTherm.

They are an essential part of the supplied items

and shall be handed over to the final user.

Annex 1: Declaration of Conformity acc. Directive 2004;22 EC (MID)

The Sensus PolluTherm is an integrator designed for measuring energy consumption in heating and cooling systems that use liquid water as the energy carrier. It can also be used with water containing antifreeze, provided a programmed correction factor is applied, though in this case, it is not officially metrologically calibrated. This device is an essential component of a comprehensive energy measurement system.

Function Description

The PolluTherm integrator calculates energy consumption based on inputs from a flow sensor and a pair of temperature sensors (Pt 500). It can function as both a heat meter and a cooling meter, with an optional "PolluTherm H" or "PolluTherm X H" version for combined heating/cooling applications. The device continuously monitors temperatures and flow rates, integrating these values over time to determine accumulated energy and volume.

For heating systems, the flow sensor is typically installed in the colder return pipe. If installed in the warmer supply pipe, the PolluTherm X version is required. In cooling systems, it is recommended to install the flow sensor in the warmer return pipe, also requiring the PolluTherm X version. The device supports various flow sensor types (AN 130, MeiStream FS, Woltman WPD FS) with specific temperature ranges.

The integrator features a comprehensive display system, organized into six menus: User, Target Day, Archive, Service, Control for Tariff Purposes, and Parameter. These menus allow users to view current and historical consumption data, maximum values, meter settings, and error messages.

Usage Features

Flexible Installation: The flow sensor can be installed in either the supply or return pipe, depending on the system type (heating or cooling) and PolluTherm version. Temperature sensors are installed at specific angles (45° for < DN 50, vertically for > DN 100) and immersion depths to ensure accurate readings.
User-Friendly Display: The device features an LC display with a red key for navigation. Short presses activate display items within a menu, while holding the key for 2 seconds accesses different menus. A flashing vane symbol indicates incoming volume pulses.
Programmable Input Pulse Value: For devices not pre-programmed at the factory, the input pulse value can be set once via the display, by pressing the red key and removing a bridge in the terminal block.
Data Interfaces and Options:
- Optical Interface: Standard on all meters, allowing data readout and settings changes via programming software (MiniCom) and optical data couplers (RS 232 or USB).
- M-Bus Plug-in Unit (EN 13757-3): Enables meter readout via primary or secondary address with an M-Bus level converter (300 and 2400 baud).
- Remote Reading Plug-in Unit (FZS/N or FZS/B): Provides heat quantity and volume pulses output for mains-operated or battery-operated devices, respectively.
- M-Bus Plug-in Unit with Two Contact Inputs: Allows connection of two external consumption meters (cold water, warm water, electricity, gas) with passive remote reading contacts.
- USB Plug-in Unit: Connects the integrator to a PC/Notebook/Handheld Computer via USB.
- LONWORKS®-FTT10A: Integrates the meter into a building automation system via LONTALK protocol.
Combined Heating/Cooling Meter (Ordering Option): Automatically switches between metering heating and cooling energy based on supply flow temperature and temperature difference.
Optional Integrated Data Logger: Stores consumption and instantaneous values (power, flow rate, temperatures) at selectable time intervals, readable via optical interface, M-Bus, or Mini-Bus.

Maintenance Features

Module Exchange: After the certification or operating life expires, only the calibrated integrator module needs to be exchanged within the casing. This involves opening the lid, removing a fastening screw, and carefully pulling out the module.
Battery Replacement: For mains-operated units supplied until September 2010, the power supply must also be replaced when exchanging the module due to a voltage change. For battery-operated units, the main battery (D) can be replaced, and a backup battery (AA 3.6V) is used for date and short-term emergency power.
Self-Checking Function: The PolluTherm is equipped with an automatic self-checking function that displays four-figure error codes (Err XYZO) in case of system anomalies, aiding in troubleshooting.
Sealing: To prevent manipulation, the meter must be sealed at specific points: flow sensor screw connections, temperature sensor installation points, and the integrator lid.
Cable Extension: Temperature sensor cables can be extended by up to 23 meters using four-wire technology (e.g., I-Y(St)Y 2x2x0.8, minimum core size 0.5 mm²) and a junction box. This ensures that cable resistance does not affect measurement accuracy.
Power Failure Backup: Mains-operated PolluTherm units with a backup battery can maintain measuring and counting operations for up to 90 days during a power interruption. After 90 days, the backup battery secures the main memory, date, and time.
