Energy saving. Reduction of heating costs. Control and monitoring of radiator thermostats. Centralized management. Simple retrofits and conversions with minimal installation effort and minimal to no structural changes to existing building and plant infrastructure. Simplest retrofit solution! Individually adaptable and usable. Scalable from individual radiators to complex holistic buildings or entire neighborhoods. Automatic control and regulation. Remote shutdown of individual radiators. Identification of defective thermostatic valves.
ZENNER BuildingLink is an IoT solution for the control of smart radiator thermostats and enables the regulation of the heating behavior of quarters, buildings or parts of buildings. With just one click, target temperatures for buildings, floors, zones or specific rooms can be adjusted to the usage behavior, thus saving up to 31.5%* energy. LoRaWAN® makes implementation fast, easy and economical.
