Presentation
SGC universal solar heating controllers are intended for the regulation of solar systems for hot water production as well as a support system for room heating. Advanced operation algorithms ensure an optimal usage of solar energy and allow for the regulation of energy efficient circulation pumps. The SGC controllers have integrated preset hydraulic systems that allow a fast and simple installation.
Application SGC67HV
- In hot water production systems with classic or vacuum collectors
- In hot water production systems with additional heat sources
- In supply device heating using solar heating system and additional heat sources
- In pool heating systems
- Single-stage supply device charging
- Two-stage supply device charging
Advantage SGC67HV
- 65 preset hydraulic diagrams,
- controllers with 3 free programmable outputs,
- rotation speed control of 2 classical pumps (RMP),
- rotation speed control of 2 energy-efficient pumps (PWM, 0–10 V),
- system regulation with 2 collector fields,
