Tio Manifold Control Set with with thermostatic mixing valve and high efficiency Grundfos UPM3 pump

The TM3 Control Group has an uniquely designed mixing valve at its heart which ensures
accurate temperature control of underfloor heating. The unique design of the internal
mixing valve components 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 20°C to 70°C. This range of temperatures suits the whole field of
underfloor heating applications, from commissioning new floor screeds to operating with
very thick floor screeds in commercial applications. The illustrations below show how the
mixing valve operates through its remote sensing thermostatic head

Key Features

  • Adjustable temperature range from 20°C to 70°C
    making it suitable for screed drying purposes.
  • Thermostatic mixing valve with remote sensor for
    accurate control of flow temperature.
  • Flow increase valve to increase flow rate for larger
    accurate control of flow temperature manifolds / heat outputs.

Low Mixing Temperature

Initially the cool liquid in the remote sensing probe, allows almost all of the primary hot water from the heat source through the valve.


Gradually the temperature of the probe rises as the underfloor circuits begin to warm up.

Depending on the temperature setting of the thermostatic head, as the temperature of the probe rises, the shuttle starts to close off the primary hot water allowing return water to maintain the temperature set on the head, up to 70°C if required.

Once the temperature set on the head has been reached at the probe, the shuttle balances the right amount of primary hot water and secondary return water to maintain this temperature.


Depending on the thermostat setting, the hot water could be almost completely closed off allowing very low temperatures suitable for commissioning screed floors right down to 20°C if required.
