The electronic heat cost allocators WHE5.. and WHE6.. are designed for decentralized installation and used when heating costs must be allocated to several consumers based on actual consumption. Temperatures are acquired by one (radiator) or two sensors (radiator and room temperature sensor). In two-sensor mode, the actual temperature difference between room temperature and radiator temperature is acquired, while in one sensor mode, a constant value for the room temperature is predefined.
These measured values are used as the basis for calculating consumption. The main areas of application are in central heating systems, where heating energy is used individually by the different consumers.
The WHE5../WHE6.. can be operated as a one- or two-sensor measuring system with product or unit scale.
Such systems are used in e.g.:
- Multi-family homes
- Office and administrative building
Typical users:
- Service and billing providers
- Housing industry and housing cooperatives
- Building service companies and real estate agencies
The heat cost allocator is used together with the following types of radiators:
- Ribbed radiators
- Tubular radiators
- Panel-type radiators with horizontal or vertical water flow
- Radiators with internal tube register
- Convectors and bathroom radiators
Compatibility
The WHE54.. and WHE63.. replaces the WHE55.. and WHE56.. In addition to improved energy management, the WHE54.. and WHE63.. can be operated in different RF modes and are compatible with the WHE55.., WHE56.. as well as WHE3.. and WHE4…The existing heat conductors of the WHE3.. and WHE4.. device families can be reused with the WHE5... and WHE6.. The non-communicating WHE50.. (B-series) is compatible with the WHE3.. and WHE50.. (A-series).
The WHE2.. cannot be replaced by the WHE5.. or WHE6.., since neither the measuring algorithm nor RF transmitter fitted in the heat cost allocator (with WHE26) are compatible.
One- and two-sensor measuring system
The joint use of different device types in one and the same property is only permitted as long as the devices use the same standard measuring system and have a standard measuring algorithm.
Two-sensor heat cost allocators can be operated unconfigured and as often as you want in a one-sensor heat cost allocator.
Limitations
Electronic heat cost allocators cannot be used in connection with steam heaters, fresh-air radiators, floor heating systems, ceiling heating elements or flap-controlled radiators.
For combined valves and flap-controlled radiators, measuring devices may only be installed if the flap control unit is removed or disabled in the "open" position.
The electronic system must be removed or disabled on convectors where an electric fan varies output or towel heaters with an electric heating cartridge, to install electronic heat cost allocators.
