4. Possible displays in the error
function
If the miniature service technician is visible in the display, the
UltraMaXX ceases to calculate the energy consumed.
Possible errors are displayed in the error code display (3.9).
5. Additional functions
5.1 Optical interface
7
The UltraMaXX has an optical interface which conforms to
EN1434 and EN60870-5. Service staff can use service software
to read out data and program parameters for the options via
this interface.
5.2 Status logger
The status logger saves the last 100 status changes of the war-
ning and error messages of the UltraMaXX. It can be read out
by service staff with the aid of service software via the inte-
grated optical interface or via an integrated M-Bus option and
displayed on a PC or laptop.
6. Options
8
Options must be specified when the UltraMaXX is ordered so
that they are integrated into the product. It is not possible to
retro-fit the options onto the UltraMaXX.
7. Combi-meters
The UltraMaXX can be ordered as a heat meter, cooling meter
or as a combi-meter.
The combi-meter combines the functions of a cooling and heat
meter into a single meter and displays the energy figures in
separate displays.
The heating energy is displayed in display 1.1 and the cooling
energy is displayed in display 1.4. In addition, the energy fi-
gures are displayed in the period-end level in displays 2.x.1 for
heat and in 2.x.3 for cooling. Switching between the metering
of heat and cold is fully automatic.
The metering of cooling occurs when there is a negative tem-
perature difference between the supply and return.
The metering of heat occurs when there is a positive tempera-
ture difference between the supply and return.
Meter not programmed.
Replace the meter by a new one.

No figure in the supply temperature, return
temperature or temperature difference (3.3,
3.4 or 3.5). See error code in display 3.9.
