Steca Suntana Solar Thermal Controller
Steca Suntana Solar Thermal ControllerThe Steca Suntana solar thermal controller is another member of our solar thermal controller family. The controller monitors and controls solar thermal systems with one collector array, one storage tank and alternatively with an appropriate back-up heating or circulation pump.
Apart from controlling the solar energy system, the controller also performs important system monitoring and safety functions. The system parameters and measured values can be viewed and modified via a 2 x 16-digit LCD display. The amount of solar energy fed from the collector array into the storage tank can be read from the LCD display at any time, thanks to a volumetric flow meter with pulse output. The controller has a maximum of five inputs for temperature measurement, a digital pulse input for recording heat quantity, and two outputs for controlling pumps. A programmable timer with selectable switching times for controlling a solar circuit pump is integrated into the controller. Installation mistakes are avoided from the very beginning through the automatic recognition of the temperature sensors. The components delivered with the controller include one collector temperature sensor and two storage tank sensors.
