General information
Thank you for having purchased
zelsius® one of the most modern heat meters
available on the market today.
A lot of helpful functions and menus will assist you in getting better acquainted with
your use of energy and your pattern of consumption.
With time, you will be able to save costs, because of having the possibility of control-
ling your own pattern of consumption.
Expressive symbols in the display and a simple user interface and menu navigation
also make working with zelsius
®
a pleasure (see the display overview also).
zelsius®is operated using a single colored button.
It is equipped with a long-life battery, designed for operation over one calibration
period, including a buffer time of at least a year.
Certification
The seal resp. the label with the year of first calibration is located on the front of the
heat meter. The calibration validity is 5 years (in Germany; other countries may have
different regulations).
Should the device be opened unauthorized guarantee and calibration validity of the
meter expire.
Interference potential
The heat meter is constructed to comply with the national and international require-
ments on interference resistance.
To avoid further interferences, no fluorescent tubes, switch boxes or consumers of
electricity, such as motors or pumps are to be installed in the vicinity of the meter
(minimum clearance 1 m). Cables from the meter may not be laid parallel to the line
voltage carrying cables (230V) (clearance at least 0,2 m).
Care instructions
Clean the plastic surface only with a damp cloth. Do not use any scrubbing or ag-
gressive detergents!!
Remote readout output (optional)
External counting inputs from pulse
counters can be accessed using the
option „remote readout output“ (see
the type plate on the side).
For the use of this option, a firmly
connected cable is included in deliv-
ery. You must take care of the exter-
nal circuits yourself (see drawing on
the right).
M-Bus (optional)
The name of the version is imprinted on the type plate, on the side of the device.

Status Displays
The status messages display the operational status of the meter in an easily under-
standable manner (see table below).
Note :
The status messages in the table below only appear in the main display (en-
ergy)!
In all cases, in which the warning triangle represents a status message, you
should check first whether the problem is permanent or occurs only temporar-
ily.
If the symbol appears permanently, a service company should be called!
A few displays can be conditional upon the system and do not necessarily mean that
the meter is defect. The warning display disappears after a short period when the
system is operating properly.
