Page 3: General Information
Declaration The Manufacturer declares that STDC E Solar Controller is marked with CE mark and meets the requirements of the following Directives: - Directive 2006/95/EC – Low Voltage Directive (LVD) - Directive 2004/108/EC - Electromagnetic Compatibility (EMC) General information Please read carefully! This Instruction Manual contains basic instructions and important information on the safety, commissioning and the best use of the Controller. -
Page 4: A 1 - About The Controller
A 2 - About the controller The STDC E controller is designed to control automatic operation of solar systems with solar collectors for heating fluids. This type is intended for use in solar systems with one collector field and one solar heat sink. - Page 5 B - Hydraulic variants The following pictures represent possible hydraulic variants of solar systems controlled by STDC E controller. The following illustrations should be viewed only as schematic diagrams showing the respec- tive hydraulic systems, and do not claim to be complete. The controller does not replace safe- ty devices under any circumstances.

- Page 27 0V = Off F 7.3 - Speed control R1 If the speed control is activated, the STDC E makes it possible to vary the speed of standard pumps at relay by means of special internal electronics. This function should only be activated by a specialist. Depending on the pump and pump stage used, the minimum speed should not be set too low, because otherwise the pump or the system may be damaged.
- Page 28 This value is the control setpoint for mode V3 (see Chapter 7.3.1). If the value at the sensor drops below this, the speed is reduced. If it rises above this, the speed is increased. Setting range: 0° to 90°C/Default setting: 60°C REGULUS - STDC E Controller - www.regulus.eu │...
