TROVIS 5576 Heating and District Heating Controller - 1

T 5576 EN TROVIS 5576 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 controller can communicate with up to six heat meters using the retrofittable meter bus plug-in module. The TROVIS 5576 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 outdoor-temperature-compensated) as well as control of DHW heating in the secondary circuit Electronics from SAMSON –– Control of one outdoor-temperature-compensated heating circuit and a DHW heating with two valves in the primary circuit –– Control of two outdoor-temperature-compensated heating circuits with two valves in the primary circuit Properties •• 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 Fig. 1: TROVIS 5576 Heating and District Heating Controller SAMSON AKTIENGESELLSCHAFT · Weismüllerstraße 3 · 60314 Frankfurt am Main, Germany Phone: +49 69 4009-0 · Fax: +49 69 4009-1507 ·

TROVIS 5576 Heating and District Heating Controller - 3

For systems with two control circuits and five pumps, the second heating circuit can only use the 0 to 10 V output. 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...
