After the last display, the previously selected set day
is displayed again. Pressing LCD button 1 selects
the next set day.
Notice: If the number of months to be read out is
changed with the service software, this will have an
impact on the number of retrievable months in the
LCD.
Service loop 4 ("LOOP 4")
Service loop 4 shows the unit parameters. LCD
button 2 calls the displays one after the other.

Previous year's values
The electronic unit stores the meter readings for
quantity of energy, volume, the tariff register, missing
time, and flowrate measuring time as well as the
current maxima for flowrate, power, temperature
difference, flow temperature, and return temperature
with their date stamps on a yearly set day.

Monthly values

The electronic unit stores the meter readings for
quantity of energy, volume, the tariff register, missing
time, and flowrate measuring time as well as the
monthly maxima for flowrate, power, temperature
difference, flow temperature and return temperature
with their date stamp for up to 60 months on the set
day of each month.
Note: The standard time used is Central European
Time (CET). If daylight-saving time is activated,
storage will be performed accordingly.
The monthly values can also be read out via the
optical and the 20 mA interface.

The number of places after the decimal point of a
value is based on the chosen measurement path
and the chosen dimension.

Power supply

The UH50 can be powered from a power supply
module or with a battery.
The lifetime of battery depends on the type of battery
and on the requirements (e.g. short timebase,
analog module etc.).
Requirements
(for measuring timebase Q = 4 s
and measuring timebase T = 30 s)
Standard pulses
M-bus read-out (max. each 15 min.),
CL module
M-bus fast read-out, fast pulses,
analog module, radio module
Automatic power supply detection
The power supply unit detects whether a line voltage
is applied. This signal is routed to the UH50. That
enables the device to detect automatically whether it
is being powered from a battery or power supply unit.
