## Summary description

SiGMA-Li RMZTP-2 is a brass manifold designed for two heating or cooling circuits, equipped with a thermostatic valve and individual flow meter. It enables balanced distribution and control of medium flow to each circuit, supports temperature regulation via the thermostatic element and provides visible flow measurement for commissioning and adjustment. Suitable for underfloor heating, radiator circuits or small hydronic systems.

## Long description

SiGMA-Li RMZTP-2 is a brass 2-circuit manifold designed for precise distribution and control of heating or cooling medium in small hydronic systems. The unit integrates a thermostatic valve on one branch and an individual flow meter on the other, allowing automatic temperature control on the thermostatic side and visible flow measurement for balancing and commissioning. Constructed from brass, the manifold is intended for use in underfloor heating, radiator circuits, or other two-branch applications where compact, serviceable flow control is required.
Advantages
The brass construction provides corrosion resistance and mechanical durability for long-term operation. Integration of a thermostatic valve enables local temperature regulation without additional actuators, while the built-in flow meter delivers direct visual feedback for balancing and adjustments. The compact two-branch arrangement simplifies installation in small systems and reduces the need for separate components, making system layout and maintenance more straightforward.
Suitable for
Two-branch underfloor heating loops in residential or light-commercial buildings
Small radiator circuits requiring individual flow control and temperature regulation
Hydronic heating or cooling systems where visible flow measurement is needed for commissioning
Retrofit projects needing a compact manifold with integrated thermostatic control
Key specifications
Material: brass body suitable for potable water heating systems and general hydronic use
Number of circuits: 2, with independent control elements
Controls: thermostatic valve on one circuit for temperature regulation and a flow meter on the other for flow indication and balancing
Visible flow measurement: graduated indicator to assist with commissioning and manual balancing
Compact design: intended for installations with limited space or for modular manifold assemblies
How to use
Install the manifold in line with the system hydraulic layout, ensuring correct orientation and secure connections to supply and return piping. Connect each circuit to its respective outlet and verify that the thermostatic valve and flow meter are accessible for adjustment and reading. During commissioning, use the flow meter to set target flow rates and the thermostatic element to achieve the required local temperature setpoint. Follow standard plumbing practices for sealing threads and bleeding air from the system before bringing it into service.
Usage recommendations
Use compatible fittings and sealing materials rated for the system pressure and temperature. For accurate balancing, perform flow adjustments and system flushing during initial commissioning; verify thermostatic valve operation at varying supply temperatures. Periodic inspection of the flow indicator and the thermostatic element is advised to ensure reliable performance.
