Commissioning
This display appears after snapping the device onto the
mounting plate. Then, the display changes to the normal
mode display loop.

Remote sensor identification
The meter has detected a remote sensor and adjusts its
measuring behavior accordingly.

Technical design
Measuring principle
The heat cost allocator is delivered as a one- or two-sensor device. The following valuation factors are set when
the units are delivered:
K
cHF
= 1.28 K
c
= 2.50 K
Q
= 1000 Exp. = 1.15
If the heat cost allocator does not work with a product scale, the consumption value (VW) must be calculated
before billing, based on the readout value (AW) and the radiator-specific K-values (K
c
, K
cHF
und K
Q
).
One-sensor device VW = 7.529 * 10

* AW * K

* K

Two-sensor device VW = 3.486 * 10

The respective K
C
values can be determined by using the K
C
value database.
Default parameters
The following parameters are set when the device leaves the factory:
Zeroing after the due date Yes
Counting progress even after a device opening was identified
Opening display as clear
text
Yes
Conversion of the consumption values is not performed if the device parameters are changed
The following parameters can be set:
Sensing type From a two to one-sensor measuring system
K
C
/K
Q
Valuation factors for calculating the heat output of a radiator (depending on the
device’s algorithm and the sensor type)
Next due date Day the annual value is stored
Device name/device
password
Device access data to prevent unauthorized device access
RF mode S-mode or C-mode (depending on the variant)
