## Summary description

Vaillant VR 70 mixing-solar module (0020184844) is a dedicated component for solar thermal installations. It provides mixing control between solar circuit and heating/ storage systems, enabling correct flow temperatures and integration of solar collectors. Intended for use with Vaillant and compatible solar-thermal systems to optimize heat transfer, temperature regulation, and system protection.

## Long description

The Vaillant VR 70 mixing-solar module is a component designed for solar thermal installations to manage mixing between the solar circuit and heating or storage systems. It ensures correct flow temperatures from solar collectors to storage tanks or heating circuits, enabling smooth integration of solar-generated heat into existing systems. The module is intended for use with Vaillant and compatible solar-thermal equipment to improve temperature regulation and protect system components from excessive temperatures or thermal stress.
Advantages
The VR 70 mixing-solar module provides stable temperature control by regulating the proportion of return and collector water, helping maintain target flow temperatures. It contributes to system protection by preventing overheating and reducing thermal shock to storage tanks and heat exchangers. The module's design facilitates straightforward integration into solar-thermal installations and supports improved efficiency of heat transfer from collectors to storage or distribution systems.
Suitable for
Solar thermal systems requiring temperature mixing between collectors and storage tanks
Integration with Vaillant boilers, solar controllers and compatible heating systems
Retrofit or new installations where flow temperature regulation and system protection are needed
Key specifications
Function: mixing control between solar circuit and heating/storage circuit
Purpose: maintain correct flow temperatures and protect system components
Compatibility: designed for Vaillant solar-thermal systems and compatible systems from other manufacturers
Application: solar collectors to storage tanks or heating circuits
Control features: temperature regulation via mixed flow—suitable for automatic integration with solar controllers
How to use
Install the VR 70 mixing-solar module in the hydraulic circuit between the solar collector loop and the storage or heating circuit according to the system design and local installation standards. Configure the module in conjunction with the solar controller so that the mixing ratio produces the required flow temperature for the storage tank or heating circuit. Verify correct sensor placement and pipe connections, then test the system operation across typical collector temperatures to ensure stable regulation and proper protection of downstream components.
Usage recommendations
Use the mixing module in combination with appropriate temperature sensors and a compatible solar controller. Regularly inspect connections and seals for leaks and schedule maintenance according to the overall solar-thermal system guidelines to maintain efficient and reliable operation.
