FMU2

FMU2 Floor Mixing Unit

Supplied as a pre-assembled mixing valve and manifold assembly between 2 and 12 ways, incorporating the TM3 Control Group that uses an integrated thermostatic mixing valve with a remote actuator to give a temperature range of between 20oC and 70oC. The FMU2 includes a Lowara EcoCirc Class A pump, ErP 2015 compliant with variable and fixed speed control with antiblock technology.

Technical Data

The FMU2 Manifold and Mixing Assembly

The FMU2 is a pre-assembled manifold and control group designed for underfloor heating systems. The combination of TM3 control group and manifold is factory tested to 10 bar and includes remote sensing thermostatic mixing valve, high efficiency circulating pump, temperature gauge, integral automatic air vent and non-return valve for easy system filling.

The pre-assembled unit can be simply fixed to the mounting surface and connected to pipework and electrical components making installation extremely simple.

Available in 2-12 ways with optional double regulating flowmeters or lockshield valves fitted to the flow bar. The return include electrothermic valves which are designed to be opened on demand by Control T electrothermic heads. The mixing valve assembly is designed to supply a set mixed temperature between 20oC and 70oC which will suit a wide range of applications. The low range has been designed to ensure that the screed drying process in carried out correctly.

An electronic actuator can be fitted to the mixing valve to give electronic control of the system when used with the RCE weather compensator.

The addition of the ErP 2015 Compliant Lowara Ecocirc circulating pump gives high efficiency operation with combined anti-block technology. The pump can be set to variable or fixed speed to overcome high resistance systems or large installations.
