Technical solution
We found a technical solution for two-way data exchange and power management of Vaillant Protherm Skat electric boilers, according to the requirements of DSTU-NB V.2.5-65:2013.
Installation of equipment
A wireless electric heating dispatching system was designed and implemented in four buildings.
Home controller
A BC-01 building controller, which is the brain of the entire dispatching system, was installed in the concierge room of each building.
Control module
A BA-01 control module manufactured by GreenHub is connected to each Protherm electric boiler, which is connected to the electric boiler via the eBus information bus.
Floor controller
DC-01 floor controllers are installed on each floor, which provide wireless communication with equipment for controlling Protherm electric boilers.
Temperature sensors
GreenHub TC-01 temperature sensors are installed in each room and connected to the BA-01 module to ensure the balancing and prioritization algorithms.
Results
Reduced power in the Technical Conditions
Thanks to the installation of the electric heating automation system, it was possible to reduce the power from electric heating in the Technical Conditions for connecting to external networks by 2 times compared to the actual installed power of heating devices.
Functionality received by the client:
