Tolerance of EN 12098 – 1; 1996 controls of heating systems – part 1; Outside temperature compensated control equipment for hot water heating systems and EN – 12098 – 2; Controls of heating systems – Part 2; Optimum start – stop control equipment for hot water heating systems have been evaluated and ASHRAE Guidelines to specifying Direct Digital Control Systems with pr. EN ISO 16484-1 Building control systems – Part 1: Overview and definitions (ISO/DIS 16484-1: 1999) and pr. EN ISO 16484-2 Building control systems – Part 2: HVAC control system functionality (ISO/DIS 16484-2; 1999) have been evaluated. Application of free programmable and fixed program controller produced by different manufacturers has been developed for interoperability in LON protocol based network. Technical and economical results of Riga district heating network retrofitting program are estimated in respect of LON protocol network development. Aspects of visualization have been taken under evaluation. Research is completed with economical calculations for alternative
