TROVIS 5575 Heating and District Heating Controller - 1

T 5575 EN TROVIS 5575 Heating and District Heating Controller Application Control of max. two control circuits. To control more circuits, several controllers can be linked by a device bus. The TROVIS 5575 Heating and District Heating Controller is used to control max. two control circuits: Control of a primary heat exchanger or boiler with max. one mixing and one non-mixing heating circuit (both weathercompensated) as well as control of DHW heating in the secondary circuit Electronics from SAMSON –– Control of one weather-compensated heating circuit and a DHW heating with two valves in the primary circuit –– Control of two weather-compensated heating circuits with two valves in the primary circuit Special features •• Rotary switches for direct access to the operating modes and essential parameters of the control circuits •• Intuitive data retrieval and input by pressing and turning the pushbutton •• Illuminated display •• 365-day clock with max. four time schedules and automatic summer time/winter time changeover; maximum three times-of-use per day (input in steps of 15 minutes) •• Room panels may be connected for each heating circuit: –– Convenient room panels for adjustment of the operating mode, the day and night set points, the times-ofuse for heating, the controller clock and party mode. Additional outdoor and room temperature readings. Connection via device bus –– Room panel to override operating mode and rated room temperature •• Demand-driven control by set point demand by subsequent controllers over a device bus or 0 to 10 V signal. The primary circuit controls the maximum flow temperature demanded plus adjustable boost. •• Applications with solar hot water system available •• Instantaneous heating systems with water flow sensor configurable Fig. 1: TROVIS 5575 Heating and District Heating Controller •• Heating characteristics optionally based on the gradient or based on four points; variable return flow temperature limitation •• Adaptation: automatic adaptation of the heating characteristic (room temperature sensor required) •• Optimization: calculation of the best possible activation and deactivation times for the heating (room temperature sensor required) •• Drying of jointless floors function with adjustable parameter settings •• Updatable flash memory in controller (operating system) SAMSON AKTIENGESELLSCHAFT · Weismüllerstraße 3 · 60314 Frankfurt am Main, Germany Phone: +49 69 4009-0 · Fax: +49

Electrical connection and installation The controller consists of the housing containing the electronics and a separate terminal board for electrical connection. Two wires of max. 1.5 mm² may be connected to each terminal. The sensor connection lines must be installed separately from the lines carrying the power supply. For wall mounting, screw the terminal board to the wall. After wiring the controller, place the controller housing onto the terminal board and fasten it with two screws. Two fastening elements for panel mounting are included. 144 Ordering text TROVIS 5575-00xx Heating and...

Terminal assignment CAUTION! Never connect terminals 12 (ground for sensor) and 13 (ground for 0 to 10 V/0 to 20 mA)! 1) A 50 Ω resistor is required between terminals 03 and 13 for applying a 20 mA signal. Fig. 5: Terminal assignment of TROVIS 5575-000x and TROVIS 5575-002x Controllers CAUTION! Never connect terminals 12 (ground for sensor) and 13 (ground for 0 to 10 V/0 to 20 mA)! 1) A 50 Ω resistor is required between terminals 03 and 13 for applying a 20 mA signal.
