DetailsVR68 Solar Module
The Solar Module VR 68 enables the Weather Compensator VRC 430 / VRC 430f to control the solar hot water system. It actively keeps the boiler off during times of solar gain and therefore maximise the solar gain into the system. All necessary solar displays automatically appear in the VRC 430 / VRC 430f and are integrated in its functionality.
The Solar Module VR 68 and the Weather Compensator VRC 430 / VRC 430f allow the combination of Vaillant solar collectors with ecoTEC system or an open vent boiler and an auroSTOR twin-coil unvented stainless steel cylinder.
The Solar Module VR 68 is designed as a wiring centre that is used specifically with the VRC 430 or VRC 430f Weather Compensators giving full solar functionality to these controls. Wiring is simplified by the use of via e-bus communication connection. All components in the solar circuit like solar pump, collector sensor, solar cylinder sensors, as well as legionella pump where used are connected to the VR 68.
