## Long description

Purmo MIX-BOX 3 with Grundfos UPM3S Auto 15-60 pumps, two SMT 83 groups, CX 2F manifold and P2 wall cabinet is a preassembled hydronic heating set engineered for domestic and light-commercial heating systems. The kit integrates circulation pumps, zone-control pump groups with actuators and a compact distribution manifold housed in a dedicated wall-mounted cabinet to simplify installation, reduce on-site plumbing work and provide a tidy service access point.
Advantages
The set combines energy-efficient circulation with modular zone control: Grundfos UPM3S Auto 15-60 pumps deliver electronically controlled variable-speed operation, while the two SMT 83 groups manage independent heating circuits through actuators for accurate room-by-room control. The CX 2F manifold offers a clear connection layout for distribution to multiple radiators or underfloor circuits, and the P2 wall cabinet provides secure, space-saving installation with easy access for maintenance. Preassembly reduces installation time and potential errors compared with separate components.
Suitable for
 Residential central heating systems with multiple zones
 Small commercial or office heating installations
 Renovation projects where compact, wall-mounted solutions are required
 Hydronic systems combining radiator and underfloor heating circuits
Key specifications
 Circulation pumps: electronically controlled variable-speed pumps suitable for automatic differential pressure regulation
 Pump groups: two preassembled groups with motorized actuators for zone control
 Manifold: compact CX 2F distribution manifold with connections for multiple heating circuits
 Cabinet: P2 wall-mounted cabinet designed for neat, concealed installation and service access
 Application: preassembled set intended for hydronic heating systems and zone management
How to use
Installers mount the P2 wall cabinet at a convenient service height and connect supply and return hydraulic lines to the CX 2F manifold following local plumbing codes. Electrical connections for the Grundfos UPM3S Auto 15-60 pumps and SMT 83 actuators must be carried out by a qualified electrician according to the manufacturer wiring diagrams. After filling and venting the system, use the pump controls to set automatic operation; the UPM3S pump adapts pumping speed to system demand. Commission each zone by checking actuator function, balancing flow where required and verifying correct temperature and pressure readings.
Usage recommendations
Use corrosion-inhibited water and perform routine system flushing and filter maintenance to protect the pumps and manifold. Follow recommended electrical and hydraulic commissioning steps and schedule periodic checks of pump operation and actuator response to ensure long-term, efficient performance.
