district heating or cooling, in building management services and in industrial energy metering.
It is part of a combined heating/cooling or air conditioning meter, consisting of a calculator, a pair of
temperature sensors and a flow meter, or as a transducer for a flow meter.
The environmental conditions described in the technical specifications, as well as the installation and
operating instructions must be complied with.
3.3 Inappropriate use
The device must not be used:
In explosion-risk zone
•
• In a wet environment (condensing, splashing or dripping water)
•
Outdoors, without suitable protection
• In environmental conditions (temperature, humidity, vibrations, electromagnetic interference etc.) that do not comply with the technical specifications
• In all other instances that do not conform to its intended use
The device can be dangerous if it is not used as intended, or not in accordance with the installation
and operating instructions. In order to avoid this, it is essential that the safety instructions, operating

Wiring diagram
The wiring diagram is on the
inside of the housing cover.
Connecting to mains power supply 100 - 240 VAC
The mains supply must be connected via a two-pole separator and be adequately protected
against unauthorised interruption.
The mains supply 100 - 240 VAC
may only be connected to the following terminals:
The device must be protected by a 10 AT external fuse.
The device is fully isolated and requires no grounding connections.
Connection to other terminals is extremely dangerous and can permanently dam-

8 Electrical connections
8.1 Connection instructions
Devices with 100 - 240 VAC connections must have a safety fuse with a max. 10 AT, and
must be capable of being made voltage-free by means of an isolating element!
The device must be connected to the same electric circuit and the same fusing, switching
and isolating elements as the corresponding heating or cooling system.
If the device is additionally connected via fusing, switching and isolating elements, then
these must be protected against unauthorised access (e.g. by security seals), so that the
device cannot be put out of operation by unauthorised persons.

9 Operation
9.1 PC-Software AMBUS Win II
The parameters of the device can be set both via keys and display and via one of the data interfaces
with the PC parameterising software AMBUS Win II.
With AMBUS Win II, the meter reading data can be saved, and parameter settings that have to be
executed repeatedly can be stored as macros, which can then be reloaded and run. AMBUS Win II
and the associated operating instructions can be downloaded free of charge at www.aquametro.com.
The use of AMBUS Win II offers advantages if:
• large data records have to be read,
• several devices require identical or similar parameter settings,
• complex applications with inputs/outputs are to be parameterized.
AMBUS Win II and instructions are available as free downloads at www.aquametro.com.
