A new system control package (NSC) of intelligent modules from Bosch Thermotechnology controls single or multiple zone hydronic systems for increased comfort and energy savings. It is similar to other multi-zone control systems for installation, wiring and set-up purposes, using plug and play wiring terminals. However, it can also have two-way communication from the boiler to the NSC’s Comfort Room Controller (CRC100) and Comfort Zone Manager (CZM100) modules. Indoor feedback/load compensation operation increases efficiency and comfort. Load compensation targets supply water temperature, similar to outdoor reset functions, allowing the boiler to fire to a lower supply water temperature to satisfy demand, increasing energy savings while reducing complexity and OA Reset curve set-up.
