## Summary description

RED-3 is a Saunier Duval multibrand mixing and solar module designed to work with the MiPro regulator (model 0020257508). It integrates solar circuit control and mixing functionality to manage temperature and flow between heat sources and heating circuits. Suitable for domestic or small commercial solar-assisted heating systems, it supports coordinated control of collectors and mixers for efficient hot water and space heating.

## Long description

Saunier Duval RED-3 Multibrand mixing-solar module for MiPro regulator (model 0020257508) integrates solar circuit control and mixing valve management in a single unit. Designed to interface with the MiPro regulator, the RED-3 module coordinates the operation of solar collectors, circulation pumps and mixing valves to maintain required temperatures and flow rates between heat sources and heating circuits. The module is intended for domestic or small commercial solar-assisted heating systems where combined solar and auxiliary heat sources require controlled mixing to ensure safe and efficient distribution of hot water and space heating.
Advantages
The RED-3 module combines solar circuit regulation and mixing control in one compact device, reducing wiring and integration complexity when paired with a compatible MiPro regulator. Its multibrand design allows it to be used in systems with different heat sources and components, supporting coordinated control of collectors, pumps and mixers. The module helps maintain stable delivery temperatures, reduces risk of overheating or scalding by controlling mixer action, and supports efficient use of solar energy within an existing heating layout.
Suitable for
Domestic solar hot water systems with auxiliary heating
Small commercial buildings using solar-assisted space heating
Systems requiring coordinated control of solar collectors, pumps and mixing valves
Installations where integration with the MiPro regulator is required
Key specifications
Functionality: Solar circuit control combined with mixing valve management
Compatibility: Designed to interface with MiPro regulator (model 0020257508)
Application: Domestic and small commercial solar-assisted heating systems
Control capability: Coordination of collector pump(s), mixing valve(s) and auxiliary circuits
Mounting: Panel- or wall-mountable module for integration in heating control panels
How to use
Install the RED-3 module according to the manufacturer's wiring and mounting instructions and connect it to the MiPro regulator using the specified communication and control interfaces. Wire the module to the solar collector pump(s), mixing valve actuator(s) and any auxiliary pump or sensor inputs required by the system. Configure the MiPro regulator to recognise the mixing-solar module and set the desired temperature setpoints, differential values and pump activation thresholds. Verify sensor readings and perform commissioning steps to ensure coordinated operation of collectors, pumps and mixers under varying solar input and auxiliary heat conditions.
Usage recommendations
Use the RED-3 module in systems with compatible MiPro regulators and follow Saunier Duval installation guidelines. Regularly check sensors, pumps and valve actuators for proper operation and perform periodic commissioning after maintenance or changes in system hydraulics to maintain safe and efficient control of solar and mixed heating circuits.
