5576

Special features

• Heating and district heating controller
• SAM DIGITAL READY
The TROVIS 5576 Heating and District Heating Controller is used to control max. two control circuits:
• Control of a primary heat exchanger or boiler
• Max. one mixing and one non-mixing heating circuit (both outdoor temperature controlled) as well as control of DHW heating in the secondary circuit
• Control of one outdoor-temperature-controlled heating circuit and a DHW heating with two valves in the primary circuit
• Control of two outdoor-temperature-controlled heating circuits with two valves in the primary circuit
• 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
• Illuminated display
• 365-day clock with max. four time schedules 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: the primary circuit controls the maximum flow temperature demanded plus adjustable boost
• 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
• Data logging function
• Integrated Modbus RS-232 communication interface
• Meter bus communication with up to six meter bus units using meter bus plug-in module
• Configuration and parameter setting using memory module or online using USB Converter 3 and the TROVIS-VIEW Software
• Alarm notification by text message (modem and access to a TAP service provider required)
• Controller flash EPROM (operating system) can be updated
• Service hotline for heating controllers from the TROVIS 5400 and 5500 Automation Systems (fees apply)
