Important information
This product must be installed professionally and in accordance with the pre-
scribed assembly guidelines and may therefore only be installed by qualied
and trained experts.
Application according to specication
The heat meter is used for the centralised recording of the consumption of
heating energy. The heat meter must be used exclusively for this purpose. The
medium is made up exclusively of water without chemical additives.
Use not according to specication
Any use other than the use described previously and any changes made to the
device constitute improper use. Uses and changes must be queried in writing
beforehand and are subject to special approval.
Warranty and guarantee
Warranty and guarantee claims are only valid if the parts in question have been
used in accordance with their intended use and if the technical requirements
and any applicable technical regulations have been observed.
Safety notes
Improper handling and excessively forceful tightening of screwed connections
can cause leaks. Observe the maximum torque stated in the manual. The
dimensions and thermal loads of seals must be appropriate for their application.
You should therefore only use the seals delivered with the device. Only use
water without chemical additives as the medium for this device.
The installed meter is a pressurized component.
There is a risk of persons suffering scolds from hot water.

Safety of lithium batteries
Certain heat meter components can be equipped with a lithium
battery. This type of battery is classied as hazardous.
VALID TRANSPORT REGULATIONS ARE TO BE ADHERED TO IN EACH
CASE! Inspection documents for the batteries used are available on request.
Handling lithium batteries
• store protected from dampness and moisture
• do not heat to above 100 °C or throw in re
• do not short-circuit
• do not open or damage
• do not charge
• do not store within reach of children
In the event of an accident, the following points must be heeded:
In the case of a leak:
- cover with sodium carbonate or an equivalent crystal soda
- make gases and vapours precipitate by spraying with water
- make sure of sufcient ventilation
- avoid any direct contact
In the event of injuries:
- If interior components of the dry element should come into contact with the
eyes, rinse thoroughly with water for 15 minutes.
- In the event of contact with the skin, wash with plenty of water and take off
soiled clothing.
- Move away from the accident spot following inhalation.
- Always consult a doctor.
In the event of a re:
- Use a Lith-X or Class-D re extinguisher.
- NEVER USE WATER FOR EXTINGUISHING PURPOSES
- Do not use CO2, halogen re extinguishers with dry substances or foam
extinguishers.
- Move away from the accident spot following inhalation and ventilate the area.
- Always consult a doctor.

Display Description
The data displayed apply for:
• Heat
• (empty) = Displayed value is the current value
• M (Memory) = Value on a monthly or due date
Displayed value is a date value:
• Day = Current date
• M-Day = Date applies for a saved annual
or monthly value
Displayed value is a checksum:
• Check =
Checksum refers to the current consumption value
• M-Check = Checksum is valid for a saved
annual or monthly value
