Automation System TROVIS 5400 Heating and District Heating Controller TROVIS 5433 Application Self-optimizing, weather-compensated flow temperature control and domestic hot water heating in max. two control circuits TROVlS Electronics from SAMSON The TROVIS 5433 Heating and District Heating Controller is used to control maximum two control circuits: - Control of a primary heat exchanger or boiler with a secondary, non-mixing heating circuit and domestic hot water heating in the storage tank system or storage tank charging system - Control of a weather-compensated heating circuit and a domestic hot water heating with two valves in the primary circuit. Special features • Direct access to the operating modes and essential parameters of the control loops using rotary switches • Intuitive data retrieval and input by turning and pressing the pushbuttons • 365-day clock with max. three time schedules and automatic summer time/winter time changeover; maximum three times-of-use per day (input in steps of 30 minutes) • Room panels to adjust the operating mode and rated room temperature • Demand-driven control via set point request of subsequent control circuits using 0 to 10 V. The primary circuit controls the maximum flow temperature required plus adjustable boost. • System with instantaneous water heating can be configured using a hydraulic pressure switch. • Heating characteristics either according to gradient or four points; variable limitation of the return flow temperature • Optimization: calculation of the best possible activation and deactivation times of the heating (with and without room temperature sensor) • Drying of jointless floor function with adjustable parameter settings • Configuration data and parameters can be exchanged using a memory pen. • Configuration and parameterization over TROVIS-VIEW software Fig. 1 • TROVIS 5433 Heating and District Heating Controller

Inputs and outputs • 7 inputs for Pt 1000 or PTC temperature sensors • One 0 to 10V input and one 0 to 10 V output to process or pass on the set point demand and outdoor temperature • Three-step or on/off outputs configurable with PI control algorithm, system with instantaneous water heating configurable with PID control algorithm Operation The TROVIS 5433 Heating and District Heating Controller is adapted to the specific plant by setting the appropriate system code number. To select the code number, refer to the system schematics described in the associated mounting and operating instructions....

Technical data * In systems with one control circuit, up to 4 pump outputs are available. Electrical connection and installation The controller consists of the controller housing containing the electronics and a separate terminal board for electrical connection. Two wires of max. 1.5 mm2 can be connected to each terminal. The sensor connection lines must be installed separately from the lines carrying the operating voltage. For wall mounting, screw the terminal board to the wall. After wiring the controller, plug the connector housing onto the terminal board and fasten it with two screws. Two...
