The Vitotronic digital control system ensures the economical and reliable operation of the entire heating system.

Common features include unified operation and simple installation, start-up and maintenance with the Rast-5 plug-in system and plug-and-work functionality.

The standardized LON bus enables a simple and complete integration into building management systems (BMS). The Vitocom 300 communication interface also allows for remote control/remote monitoring of the heating system.

The benefits at a glance: 

• Control of a 2-stage or fully modulating burner.
  
  
• Tie-in of additional zones with mixing valves possible (with Vitotronic 300 and Vitocontrol-S).
  
  
• Integrated boiler limits.
  
  
• Integrated failure diagnostic system.
  
  
• Programming unit with digital 7-day clock, separated for two zones and domestic water, shut-down program for 99 days.
  
  
• Limit for heating curves, pump logics and burner operating hour counter (with Vitotronic 300 and Vitocontrol-S).
  
  
• Using the cascade control Vitocontrol-S, it is possible to operate up to 4 boiler controls and 32 mixing valve zones via LON BUS.
  
  
• Digital technology allows for connection to a building management system via gateway.
  

Models for use in single-boiler systems: 

• Vitotronic 100, GC1
  
  Digital boiler setpoint control designed for external demands from BMS and DDC systems using a 0-10 VDC or LON signal or maintaining constant boiler water temperature without demands. Provides easy single cable connection to the Vitocrontrol-S for multiple boiler application. Domestic hot water heating is a standard feature with this control.
  
  
• Vitotronic 300, GW2
  
  Digital outdoor reset boiler control for modulating burner, boiler water temperature and up to two heating circuits with mixing valves. Domestic hot water heating is a standard feature with this control.
  

Models for use in multi-boiler systems: 

• Vitocontrol-S, CT3 / VD2
  
  Digital outdoor reset cascade control for up to four heating boilers (in conjunction with Vitotronic 100 GC1 controls). Designed to operate with or without setpoint demands from BMS or DDC systems. The Vitocontrol-S will modulate burners, stage and rotate boilers, regulate boiler water temperature, common supply temperature and up to two heating circuits with mixing valves. Domestic hot water heating is a standard feature with this control.
