The perfect interface between boilers and your heating system. Operates as stand alone device on all Evolution (EVS, EVSW or EVCA) or Solaris product models or easily integrates into todays BMS (Building Management Systems) with Modbus protocol. TSBC controls modulation of firing rate locally or by remote, has simple peer-to-peer staging with plug-and-play RJ11 telephone cable, and uses advanced PID (Proportional Integral Derivative) logic to optimize system efficiency by precisely matching boiler output to current building heating load.
