Differential controllers SGC16H | SGC26H | SGC36HV | SGC67HV They feature domestic hot water heating control, storage tank loading and energy source management such as: solid fuel boilers, pellet, oil or gas boilers, heat pumps or electric heaters.

Differential controllers SGC Introduction 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....

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 and yearly diagrams. - For informative...
