Technical Data Sheet Differential controllers SGC universal differential controllers are intended for the control of solar systems for domestic hot water heating as well as a support system for room heating. Advanced operation algorithms ensure an optimal usage of solar energy and provide the control of energy efficient circulation pumps. The SGC controllers have integrated preset hydraulic schemes that provide a fast and simple installation. Typical application - In domestic hot water heating systems with flat or vacuum collectors. - In domestic hot water heating systems with auxiliary heat sources. - In storage tank heating systems using a solar system and auxiliary heat sources. - In pool heating systems. - For a single-stage storage tank loading. - For a two-stage storage tank loading. - Up to 65 preset hydraulic schemes. - Up to 3 freely programmable outputs. - Speed (RPM) control of standard pumps. - Speed control of energy-saving pumps (PWM, 0^10 V). - Control of collector field systems. - Control of storage tank systems. - Possibility to control heating systems using a solid fuel boiler. - Option of using stratified storage tank loading with a quick start function in the case of a cold storage tank. - Wizard for an easy and quick device start-up. - Measurement and display of generated energy. - Solar system protection when collectors are overheating. - Notifications on the activated protection functions and warnings about system failures. - Possibility to simulate sensors and analyse the system operation. - Remote control with the help of the SeltronHome system. Description of settings buttons 2 - lisc Move backwards key. 4 - Move left or reduction key. 5 - Move right or increase key. 6 - (0K1 Menu entry or selection confirmation key.

Operation mode with several storage tanks Constant operation in the “OPTIMUM” mode means an optimum use of solar energy for heating all of the storage tanks taking into account the preferred storage tank The "AUTO" operation mode automatically switches between winter and summer modes according to a preset calendar Constant operation in the “SUMMER” mode means the heating of only the preferred storage tank, other storage tanks are heated only when the preferred one reaches the desired temperature Continuous operation in the “WINTER” mode means an alternating parallel heating of all storage tanks...

Technical Data Sheet Outlined functions Start-up wizard The SGC controller is equipped with a start-up wizard, which takes you through the initial setup of the controller in 2 steps. Step 1: language selection. Step 2: hydraulic scheme selection. Step 1 When the solar system is also used for domestic hot water heating, we want to know how much heating energy has been obtained from the solar system. 1 2 3 4 5 6 7 8 9 101112 Measurement of the energy obtained The SGC controllers provide an informative and accurate measurement of the solar energy obtained and the display of the data in weekly, monthly...
