The in-line solution for both high and low temperature systems Manifold solutions are usually thought of as only for underfloor heating applications. Today there are a large number of applications where both underfloor systems and radiators or towel rails are all part of the same heating system. The is designed to cater for both high (wall hung radiators) and low (underfloor heating) temperature applications in a simple to use, compact format. The Touch illustration screen above shows the Programmable convenience of the in-line format thermostat of manifold when thermostat connecting to both radiators and underfloor circuits. This means that both radiators and underfloor circuits can be connected in the same way with the same benefits in terms of: Installation - point to point plumbing - no joints to leak below floor level and the convenience of flexible plastic pipes to and from the manifold for each circuit Controlability each room, whether heated by radiators or underfloor circuit can be controlled separately with its own thermostat. Emmeti have a great range of controls for both wired and wireless applications together with wiring centres and remote sensors to ensure that the installer has a range of solutions to meet any system application Economy precisely because the system can be accurately controlled, room by room, zone by zone, it offers great scope for reducing room temperatures and minimising operating times, with the use of programmable thermostats, the user can save as much as 20% (depending on the property and system) so saving energy costs. Flexibility the M3V control group at the heart of the manifold assembly is purpose designed to offer both fixed temperature thermostatic control of the underfloor heating system or variable temperature control such as weather compensation using the same control group with different controls from the Emmeti range to give exactly the kind of performance being looked for Convenience the in-line format of the manifold means WIRED HETING CONTROLS that both underfloor heating and radiator circuits can Dial thermostat be connected in exactly the same way. The FCU Floor Control Unit is available with a selection of high and low temperature circuits pre-assembled to the M3V control group in a range of options designed to give maximum flexibility in meeting the requirements of the heating system. It is also available as a control group only so that the customer can match their requirements from Emmeti s comprehensive manifold range Ease of commissioning - because each circuit can be separately balanced using our patented flowmeters and lockshields, each circuit is accurately balanced at a single central control point to ensure optimum performance 2
M3V Control Groups How does it work? Boiler Flow General 2 1 10 Boiler Return Fig. 1 7b 7a 8 t the heart of the is the M3V Control Group which uses a PP composite resin moulding to create a compact format with built-in components such as the mixing valve, air vent, fill and drain valve. It is available with a choice of Integrated circulating pumps. The has a Wilo Hu 1/6 three speed pump; the Plus has a Wilo E2/1- variable speed, class B pump. Both versions have built-in isolating valves to facilitate replacement of the pump if necessary. They both comply with ErP regulations. Both versions offer a choice of temperature control head for the mixing valve. The thermostatic head and remote sensor for fixed temperature heating applications (provided) and a 3-point motorised actuator (not provided) which can be used in variable temperature applications for both heating and cooling combined systems, with a BEMS system such as RCE weather compensating kit. Operation In normal operation, the mixed low temperature water supplied to the underfloor heating system is controlled either by the thermostatic head with remote temperature sensor (illustrated and purchased separately or alternatively the 230V, 3-point motorised actuator fitted to the mixing valve (optional extra). 9 3 4 10 Underfloor Return 12 Underfloor Flow 1.

The calibration and bypass valve (2) controls the bypass flow rate of the underfloor heating system, ensuring that the design ΔT is reached. Differential pressure bypass valve operation The high temperature bypass valve 7 in Fig. 2 keeps the inlet pressure constant, consistent with the maximum high temperature flow rate required by the system, in the event of manual or automatic shut-off of high temperature circuits that are installed. The low temperature bypass valve 7B in Fig. 3 keeps the underfloor system pump pressure constant in the event of manual or automatic shut-off of the low temperature circuits. The valve recirculates part of the circulator flow to the intake of the circulator itself as shown. The Plus models have a variable speed circulator which automatically keeps the pump pressure constant and so do not require the low temperature bypass valve. 7 7B Fig. 2 Fig. 3 High temperature differential pressure bypass valve Low temperature differential pressure bypass valve 3
