Characteristics:

• two temperature sensor inputs
• floating relay output with varistor protection
• Minimum running time, minimum break time and wheel lock control for pump output
• System temperature rise protection
• Collector minimum temperature
• Manual operation
• Temperature difference and maximum and/or target temperature adjustable
• Functional announcement
• Temperature display (only ZPR-D)
• DIN rail assembly

Documentation

The solar thermal controller SOL3-1 serves for the control of solar thermal systems with one collector field. It has two temperature sensor inputs and two floating relay outputs.

The automatic controller is characterised despite complex function of extent by a serving which can be handled intuitively surface. So the announcement can be switched on the level of information with rotatary push button between the time and the temperature sensors, the supervisor states always in the view in the information level. The most important settings (switching on and off swell) are directly accessible over the rotary switch. In the parameter level extensive settings are possible, e.g. minimum pump running time and minimum break time, absolute min. and max. temperature at the collector.

The solar thermal controller SOL71 is an application to control simple to complex solar thermal systems using the programmable logic controller SAMSON TROVIS 5571 (PLC). The solar control spoils with special control comfort.

On the large display the diagram of the current operating parameters of the system is visible - the pollution free power production becomes experiencable so not only by the warmth feeling, but also by the presentation.

The selection of one from more than 100 hydraulic system variants effected on the grafic display by addition and/or deselection of components.

The control is expandable as well as control technical function range extension, so that also special systems with more temperature sensors, storage tank pumps or valves, additional heating circiuts or also fans can be integrated.

Features:

• universally applicable, simple assembly, simple operability
• grafic display for system presentation
• pump speed control for up to 4 pumps
• less than 2 W in standby operation
• integrated heat meter and counter for hours of operation
• 17 universial sensor inputs
• 12 floating relay outputs
• binding at building control system and Internet possible
• up to 2 collector arrays, 2 storage tanks, heat exchanger, heating circuit, auxialary heating, domestic hot water circulation
