Control of district heat substations Reliable and energy-efficient Answers for infrastructure.
District heating control: for trouble-free and energyefficient network operation Thanks to efficient power generation, combined heat and power and the recovery of residual and waste heat, district heating plants are an environment-friendly alternative for the separate generation of electrical power and heat. This way, emissions of thousands of tons of CO2 per year can be prevented.
■ Comprehensive range of district heating controllers and systems Siemens range of district heating controllers and systems covers the entire area of application: From power generation and distribution to commercial and residential usage, from controllers for standard applications to communicating and freely programmable automation systems for complex building services plants.
RVD range – RVD240 Synco 700 – RMH760B District heating control for every application area ■ RVD range of controllers for standard district heating plants The district heating controllers of the RVD range excel in functionality and straightforward and uniform operation. The affordably priced RVD110 and RVD130 are suited for basic substations where communication is not required. Preconfigured standard applications simplify commissioning.
DESIGO PX automation system – PXC36 ing, time programs and trend data storage satisfy all types of requirements. The automation stations work autonomously and decentrally and are available in two product lines. Communication takes place via the open BACnet™ protocol on LonTalk®, Ethernet/lP, or via modem. DESIGO PX OPEN is designed especially for universal and open communication, supporting easy and favorably priced integration of third-party systems and devices.

Energy efficiency thanks to patented DRT limitation The return temperature is an important criterion for ensuring economical operation of district heating networks. Heat transfer capacity, pumping power, heat losses and efficiency depend on it. To ensure that the return temperature in the network is kept as low as possible, Volumetric flow (primary side) the district heating controllers supplied by Siemens acquire the difference between the primary and the secondary return temperature and limit it.
