Manual Integrator Supercal 531 06-06-2011 57
9.5 Open System (In development)
In open heating systems one flow sensor is installed in the supply- and one in the return pipe. The
Supercal 531 (Supercal 533) calculates the heat energy consumption with the temperature differ-
ence and the two flow volumes.
9.6 Power Supply
Batteries or power supply modules can be used. Retrofitting is possible at any time. The Supercal
531 automatically detects the type of power supply installed.
9.7 Error Output
The error output can be used as alarm contact to signalize the freely selectable error statuses of
the heat meter.
The error outputs are programmed with the service software Prog531.
An error output will be active if at least one of the selected error messages of the heat meter is
triggered.
9.8 Energy-assessing hot water meter / 1 sensor
system
The integrator Supercal 531 (Supercal 531) can be set at the factory as energy-assessing hot wa-
ter meter.
Up to12 fixed monthly return temperatures can be set (via the tariff functions) as fixed values ac-
cording to the customer’s requirements and used as control elements. The temperature difference
can be programmed in steps of 0.5 K.
