2 FMU Floor Mixing Unit FMU - Floor Mixing Unit The FMU Floor Mixing Unit is a pre-assembled competitively priced manifold designed for underfloor heating systems. Enabling you to purchase more simply, involves less risk and administration and will reduce installation time. Included in the FMU Floor Mixing Unit is a TM Thermostatic Control Group, Lowara Ecocirc circulating pump, temperature gauge, mounting brackets and swivel joints for connection to the manifold assembly. Available from way - way fixed at mm with options of either flowmeters or locksheilds on the flow rail. Both the flowmeters (FM) and locksheilds (LS) are double regulating with isolation function. The return rail has a blue capped integrated electrothermic body (ready for the electrothermic head) per circuit. The TM thermostatic mixer included in the FMU Floor Mixing Unit ensures that hot water from the heat source and return water from the underfloor circuit are mixed together in the valve body to produce a range of temperatures from o C to o C. This range of temperatures suits a wide range of underfloor heating applications, from commissioning new floor screeds to operating with very thick floor screeds in commercial applications. Another key component to the FMU is the Lowara Ecocirc pump. High efficiency single wet rotor circulators with fixed or variable speed and threaded connections. The Ecocirc is a high efficiency circulator using a shaft less spherical motor design. This design combine s high efficiency and low noise. The Ecocirc is, ErP compliant It also has a high magnetite resistance due to the revolutionary Anti-Block technology prolonging the life span of the pump.

4 FMU Floor Mixing Unit FMU - Floor Mixing Unit Thermostatic Mixing Valve Exploded Diagram The FMU Floor Mixing Unit incorporates a TM thermostatic mixer which ensures accurate temperate control of underfloor heating. The unique design of the internal mixing valve components ensure that hot water from the heat source and return water from the underfloor circuit are mixed together in the valve body to produce a temperature range between C to C. This temperature range suits a range of underfloor heating applications from commissioning new floor screeds to operating with very thick screed in commercial applications.

7 FMU Floor Mixing Unit How the TM works - Low Temperature Thermostatic head set to a low temperature (e.g. for commissioning with a new floor screed). The mixing valve has almost closed off the primary hot water and is mixing a higher proportion of return water into the mixing chamber which reduces the mixed water temperature right down to o C if required.

9 FMU Floor Mixing Unit Setting the Flow Increase Valve Δp [mbar] Mixing Perdite unit carico pressure gruppo drops miscelazione Kv= Kv=, Kv=, Kv=, Kv=, Kv=, Once the total flow rate of the system has been calculated: Qip = total underfloor system flow-rate = (P [W] x.) / (ΔTip) Where P is the total calculated heat demand in Watts and ΔTip is the calculated temperature difference across the underfloor system the pressure drop for the mixing unit can be read off on the graph above. The mixing unit pressure drop curves show the Flow Increase Valve settings from fully closed to fully open and allow the installer/ designer to choose a suitable flow rate and pressure drop to suit the system. Together with the calculated pressure drop of the underfloor system and manifold, the pump setting can then be chosen. The tables below show two examples of required system output against the Flow Increase Valve setting based on assumed values of underfloor flow temperature, temperature drop and pressure drop for the underfloor system for guidance.

10 FMU Floor Mixing Unit FMU - Floor Mixing Unit Lowara Ecocirc Pump High efficiency single wet rotor circulators with fixed or variable speed and threaded connections. The Ecocirc is a high efficiency circulator using a shaftless spherical motor design. This design combine s high efficiency and low noise. The Ecocirc is, ErP compliant It also has a high magnetite resistance thanks to the new Anti-Block technology. Quick and easy to install Energy Saving High efficiency and long term quiet operation Only one moving part No common shaft, shaft seals and conventional bearings No back bearing No air vent bleed valve Floating spherical impeller LED light showing the status of the pump Speed selector switch with automatic regulation Self realigning ultra-hard ceramic ball bearing Antiblock device Permanent magnet electronically commutated type motor. Anti-Block Technology The new anti block technology separates the main flow of the pumped media, completely from the permanent magnetic parts The main flow of the pumped media (blue) and its magnetite and sludge particles (red) flows outside the influence area of the permanent magnetic rotor (bottom). The side flow of the wet running circulators, which is required for lubrication and cooling of the bearing is separated from the main flow which contains the magnetite and sludge. Optimised motor technology The integrated over temperature protection can automatically reduce the speed of the pump or even make it stop and start again to protect the electronics and the bearing in case of dry run situations Easy to access The screw ring design results in a pump motor that be rotated in any positions around the circle. The electrical connection as well as the control knob is therefore easy to access. Automatic air venting mode Easy to control Two in one control: Step-less manually control with constant speed, displayed by a white LED, or alternatively Automatic differential pressure, displayed by a blue LED.
