Mounting as a cold meter
When mounting a cold meter or combined heat/cold meter, make sure the black cover on the measuring tube is oriented to
the side and downward (because of water condensation).
The electronic unit must be separated from the flowrate measuring tube and, for example, mounted on the wall (split moun-
ting). Make sure that condensed water cannot run along the connected pipes into the electronic unit (building a loop down-
wards).

Power supply

The heat meter can be powered either with a battery or via power supply modules. The 110 V / 230 V power supply modules
are encapsulated and comply with safety class II. The modules can be retrofitted or upgraded at any time.
In the standard version, a battery is inserted in the factory. This must not be opened. It must not come into contact with water
or be exposed to temperatures exceeding 80°C. Used batteries must be disposed of at suitable waste disposal facilities.
In a special version, a power supply module can be installed. In the 110 V AC and 230 V AC versions, a cable is brought out
in the factory that must be connected to the line voltage accordingly. The 24 V AC/DC version has terminals instead of a
cable.
The 110 V or 230 V power supply unit must be fuse-protected with 6 A near to the heat meter and protected from tampering.

Insert the battery

Press the four side tabs of the housing cover inward and remove the cover. Then turn the label plate counterclockwise until
you feel it has gone as far as it will go.
Swing open the red locking hatch to expose the relevant battery compartment (left compartment for 2x "AA" or "C", right com-
partment for "D").
Insert the battery into the relevant compartment of the electronic unit with the correct polarity as marked.
Turn the label plate back clockwise into its original position.
