Service loop 3 (“LOOP 3”)
Service loop 3 shows the
monthly values
. LCD
button 1 is used to select a month out of the 18
previous months. The data for that month are then
opened with LCD button 2. Each further press of
LCD button 2 shows the next value for the selected
month.

Quantity of heat on the set day
Tariff register 1 on the set day
Volume on the set day
Max. flowrate on the set day,

Max. heat power on the set day,
at 2s intervals with date stamp
Max. temperatures on the set day,
at 2s intervals with date stamp
for flow and return maximum
Missing time count on the set day
After the last display, the previously selected set day
is displayed again. Pressing LCD button 1 selects
the next set day.
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 heat, 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 heat, 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 18 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.

Power supply
The UH50 can be powered from a power supply
module or with a battery.
The type of battery used for battery operation
depends on the requirements.

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.
