Controls

SUNMARK’s solar heating plants run with quality control systems

SUNMARK’s solar heating plants run with standard control systems based upon standard PLC equipment and a local touch screen panel.

SUNMARK CONTROLS are used for adjustment of e.g. the flow and temperature of the liquid which circulates in the solar heat circle.

The controls have following advantages:

• Operation and control through a local operation panel.
• Possibility to connect to superior systems.
• Regulation of the pump speed resulting from radiation and temperatures to achieve a constant supply line temperature.
• Collection of production data.
• Integrated alarm system, which registers and shows alarms.
• Trend system for showing temperature and plant data.
• Report system for showing and storing production data.
• Distal service via the internet.
