## Long description

The Afriso mixing module BTU 501 AP for underfloor heating integrates a hydraulic mixing assembly with an ATM 561 temperature control valve and an AFRISO APH 15-7/130 circulation pump to manage supply water temperature for heated floor systems. The unit blends water from the primary heating circuit with return flow to deliver a stable, adjustable forward temperature to the underfloor manifold. It is intended for residential and light commercial underfloor heating installations where precise temperature control and dependable circulation are required.
Advantages
The mixing module combines temperature regulation and pumping in a compact assembly, reducing installation complexity and saving space in plant rooms or service cabinets. The ATM 561 control valve provides accurate modulation of mixing ratio to maintain the selected supply temperature. The integrated AFRISO APH 15-7/130 circulation pump ensures continuous and reliable flow through the underfloor circuit, designed for low-noise operation and energy-efficient performance. Materials and hydraulic connections are arranged for straightforward integration with typical manifold and boiler systems.
Suitable for
 Domestic underfloor heating systems requiring a controlled supply temperature
 Small commercial or light commercial heated floor installations
 Renovation projects where a compact mixing and pumping solution is needed
 Systems using a central boiler or heat source with a separate underfloor circuit
Key specifications
 Integrated hydraulic mixing module with control valve and circulation pump
 Temperature control via ATM 561 mixing valve for adjustable forward temperature
 AFRISO APH 15-7/130 circulation pump suitable for underfloor heating flow requirements
 Compact assembly for wall- or cabinet-mounted installation near manifolds
 Connections compatible with standard underfloor heating piping and manifolds
How to use
Install the mixing module in the plant room or distribution cabinet close to the underfloor manifold and primary heat source. Connect the primary supply and return lines, the underfloor circuit feed, and the return connection according to hydraulic drawings and local plumbing codes. Set the desired supply temperature on the control valve or associated actuator following system design requirements. Commission the pump and verify flow through each circuit, adjusting balancing valves on the manifold if present. Perform system flushing and fill procedures, then check temperature stability under normal operating conditions.
Usage recommendations
For reliable operation, ensure correct hydraulic balancing and periodic inspection of the circulation pump and control valve. Use corrosion-inhibited fill water and follow local regulations for pressure testing and safety devices. If in doubt, consult a qualified heating installer for commissioning and maintenance tasks.
