Zenner caltos-E
Description
The caltos E electronic heat cost allocator precisely records radiator heat consumption using advanced temperature measurement. Its integrated wireless M-Bus (wM-Bus) interface ensures reliable data transmission for modern sub-metering applications.
Configuration
The device is delivered pre-configured.
Wireless M-Bus Address Configuration
Where to Find the Address on the Device
The address is located at the very bottom of the device, as shown in the image below (8 digits).
Mapping the wM-Bus Address to CHESTER
The mapping must be carried out using the CHESTER Terminal, for example with:
Managing and Adding wM-Bus Device Addresses in CHESTER
Here you can manage the list of wM-Bus addresses (add/remove), adjust scan settings, and review example configurations for typical setups.
- Address List Configuration: manage and edit the list of linked wM-Bus addresses
- Scan Configuration: adjust scan settings for device communication
- Example Configurations: reference templates for typical setups
Message Encryption and Key Management
The transmitted messages are encrypted to optimize energy consumption during data transmission, which extends the overall battery life.
The received data must therefore be decrypted, which is done using decryption keys.
To achieve this, there are two options:
- HARDWARIO Cloud: tutorial on how to enter and manage decryption keys
- Decryption page: online tool for manual data decryption and analysis
