Heat Cost Allocators

The new models succeed the series 555 and 556. They offer maximum flexibility in parameter setting, notably simpler installation and commissioning, as well as improved follow-up of consumption rates. All three offer Swiss precision, maximum ease of use, highly reliable transmission and guaranteed fair invoicing for the final customer.

Simple installation

Thanks to preinstalled seal, the devices are simple and fast to install. Commissioning is automatic. Registration is also extremely easy via a barcode on a removable sticker.

Impressively secure

Prog6 software allows up to 45 different parameters to be set via a standardised optical interface. Only authorised persons can change these parameters. The software itself is also equipped with a password function.

Reliability

The devices feature high reliability when transmitting the energy consumed. They have undergone a 10-year-equivalent load test – the typical lifespan of the 3V lithium battery and thus the device’s scheduled operating period.

Traceability

The devices store up to 144 monthly and 18 semi-monthly values. 18 monthly values of the highest radiator temperature are stored. This guarantees high traceability, for example when tenants change.

User-friendly

Transmission of consumption rates and stored parameters is also possible on site via the optical interface. Sontex 566 and 868: the meter can be read off both remotely by a data collection centre or mobile close to the meter’s location.

Precise room temperature

Thanks to a special algorithm, Sontex’ new-generation heat cost allocators register the room temperature much more precisely than comparable products.
