FAUN is a device designed to be used in installations with water as a heating/cooling factor. It works perfectly
in heat distribution centres, residential buildings and functional buildings, industrial buildings etc.
Depending on its design and configuration, the calculator can work as:
- heat meter for heating installation
- heat meter for cooling installation
- heat meter for heating and cooling installation in one circuit
- Possibility of cooperation with heat transducers with ultrasound or rotor impulse output available on the market
- Possibility of cooperation with temperature sensors Pt100 or Pt500, in a 2 or 4-wire system
- Possibility of installation directly on flow transducers *)
- Environmental class C (M1, E1)
- Independent opto-connection
- Power supply versions: battery (possible application of various types of batteries, battery life 6 or 12 years) or internal power supply 230 VAC
- In standard version 4 configurable impulse inputs (additional possibility of functional change into alarm inputs or inputs for digital communication with a transducer)
- More than 5000 registers of measuring data archiving, to be configured by the user
- Two independent tariff registers (superliminal registers), possible configuration of the following thresholds: power, flow, power supply temperature, return temperature, temperature difference, tariff data archiving
- Independent registers of occurrences and failure modes, configuration changes
- Additional digital communication with ultrasound transducer that identifies the transducer errors, among others the return flow, weaker measuring signal, air-locks
- Dedicated software (for PC) for the configuration of parameters of the calculator and for the reading of all current and archived data
Removable communication modules
- M-Bus
- RS232
- RS485
- Impulse outputs (2 outputs)
- Impulse outputs and inputs (2 outputs class OB, OC, or OD and 2 inputs class IB or IC)
- Analogue outputs (2 outputs, 4-20 mA or 0-10 V)
- LonWorks
- radio module Wireless M-Bus
- radio module for telemetric systems IMR
Communication protocols
- M-Bus in conformity with: PN-EN 13757-2:2005, PN-EN 13757-3:2013
- Modbus in conformity with specification Modbus RTU
- Lumbus
- LonWorks
- Cooperates with devices working in OMS standard
FaunService program for configuring Faun calculators, in particular:
- general parameters of operation with the converter: pulsing constant, nominal flow rate
- operation mode: heat meter or heat/cool meter or cold meter, including setting the cold measurement threshold
- setting the measurement unit
- parameterization of communication modules (Mbus, ModBus, Radio WMBUs)
- settings of pulse inputs (pulse value, initial state, etc.)
- insensitivity of DT measurement - energy is counted from the temperature difference (in the range of 0.1oC to 3oC)
- settings of charging tariffs
- archive settings
The program is not used for reading archive data.
The program requires an optical port with USB (product index: 0923-410-011)
