5578-E

Special features

• Heating and district heating controller
• SAM DIGITAL READY
The TROVIS 5578-E Heating and District Heating Controller is used to control max. three control circuits:
• Control of a primary heat exchanger or boiler with max. two mixing and one non-mixing heating circuit (both outdoor temperature controlled) as well as control of DHW heating in the secondary circuit
• Outdoor-temperature-controlled buffer storage tank control with max. two mixing heating circuits and continuous-flow hot water module
• Control of two outdoor-temperature-controlled heating circuits and a DHW heating with three valves in the primary circuit
• Control of three outdoor-temperature-controlled heating circuits with three valves in the primary circuit
• Extension to 6 control circuits with expansion module TROVIS I/O
• Direct access to the operating modes and essential parameters of the individual control circuits using a rotary pushbutton
• Enter and retrieve data intuitively by turning and pressing the button
• LC display with plain-text and icons
• 365-day clock with max. four time schedules (without TROVIS I/O) and automatic summer time/winter time changeover
• Max. three times-of-use per day (entered in steps of 15 minutes)
• Room panels can be connected for the individual heating circuits
• Demand-driven control by set point demand by subsequent controllers using device bus or an 0 to 10 V signal
• Applications including solar thermal DHW available
• Instantaneous heating systems with water flow sensor configurable
• Heating characteristic optionally based on gradient or four points
• Flexible limitation of the return flow temperature
• Adaptation: automatic adaptation of the heating characteristic (room temperature sensor required)
• Optimization: calculation of the best possible activation and deactivation times for heating (room temperature sensor required)
• Drying of jointless floors function with adjustable parameters
• Controller flash EPROM (operating system) can be updated
• Integrated meter bus interface for communication with max. three meter bus units
• Galvanically isolated RS-485 interface for Modbus RTU/device bus communication
• Ethernet interface for Modbus TCP/IP communication and connection to SAM DISTRICT ENERGY
