3.5 Characteristics
 Measuring by two temperature sensors, radiator and ambient temperature sensor (NTC-
resistor).
 Optional measuring principle: 1 sensor mode with start sensor or two sensor mode.
 Unit scale or product scale.
 Recording of cumulated heat consumption on the annual set day.
 Recording of 144 monthly values and 18 half monthly values for cumulated heat
consumption.
 Recording of 18 monthly values for the maximum radiator temperature.
 Optical interface for the readout of the data and programming
 For heat cost allocator Sontex 566 Radio, the Sontex radio system (Supercom) is a bidi-
rectional system. Reading and programmable by radio.
 For heat cost allocator Sontex 868 Radio, the radio module comprises a unidirectional radio
transmitter.
Two telegrams: short telegram, OMS compliant and long telegram for Walk-by reading.
 User-friendly operation by push button.
 6-digit and high-contrast LCD display.
 Automatic commissioning during the mounting on the aluminium back plate (available
when ordering).
 Check code for postcard mail-in method
 Possibility to connect a remote sensor on each version of heat cost allocator. The remote
sensor will be automatically detected by the heat cost allocator.
 Remote sensor version with 2 m cable.
 Standard aluminium back plate for nearly all existing bolts with common dimensions and
installation possibilities – thus easy installation (no cutting and welding of bolts necessary).
 Snap-on blind to cover colour shadows for increased aesthetics.
 Safe operation and fraud/manipulation detection.
 Lithium battery with a capacity of up to 10+1 year.
 Meets EN 834:2013.
3.6 Display
The heat cost allocator has a LCD-display with 6 large main digits on the right and 2 smaller di-
gits on the left as well as two special symbols and one communication indicator. The main digits
are separated by four decimal points. Below, please find the display segments:
Normally, the heat cost allocators 565 / 566 / 868 / 878 are supplied with switched-off LCD-
display. On request, the heat cost allocators can also be supplied with permanent LCD- display.
3.7 Electronics
The device has an electrical circuitry with a micro controller of the latest generation with
extremely low current consumption operating at a voltage as from 1.8 V.
The temperature measuring circuit with automatic self-calibration measures the discharging
time of a capacitor. The accuracy of the measuring circuit is independent of the supply voltage.
