T3 UFH Control Group with thermostatic mixing valve, electrothermic head and pump – U9700033
Using a similar specification to the U9700090 Control Group above, the thermostatic mixing valve incorporates a thermal actuator, which when de-energised, shuts off the flow of hot water through it, to the Underfloor heating manifold. The actuator incorporates an auxiliary switch to operate other equipment, e.g. boilers. This enables the Control Group to be used in four different applications:
1. Isolation of the manifold when the pump and valve are de-energised
2. Where an additional level of temperature control is required to ensure that a maximum floor temperature is not exceeded. This requires a suitable safety thermostat.
3. Single zone applications, when a minimum water temperature is required to switch the zone on. This also requires a suitable safety thermostat.
4. Single zone applications where the actuator auxiliary switch energises the boiler and primary pump in conjunction with an existing controls system for heating and hot water.
The Group includes as standard a temperature gauge measuring the mixed flow temperature, and a supporting bracket to support the weight of the pump. It includes a non-return valve to assist filling the system. It has the same compact overall dimensions as the range.

T3 UFH Control Group with motorised mixing valve and pump – U9700043
Designed for applications where both a higher flow and flexible control of water temperature is required. This allows the Control Group to be used with a range of temperature control options.
To complete the product, specify one of three temperature management actuators which mount directly on the valve.
- Actuator only U9750010 for use with an external temperature control system
- Actuator U9750021 with built-in fixed temperature controller complete with remote water temperature sensor
- Weather compensating controller U9750030 complete with water and outside temperature sensors
The Group includes as standard a temperature gauge measuring the mixed flow temperature and a bracket to support the weight of the pump. It includes a non-return valve to assist filling the system. It has the same compact overall dimensions as the range.

Can you install the T3 control set upside down? Yes:- the mounting bracket will need to be re-fixed so that it can be secured to the mounting surface and the pump rotated to the front.
What are the 6 temperature settings equivalent to on the T3 UFH Control Set? 35°C - 40°C - 45°C - 50°C - 55°C - 60°C
Can a T3 UFH Control Set be used with another branded manifold? Yes, if the centres and connections of the manifold are compatible.
What is a ‘shunt unit’? A 'shunt unit' is the description given in Nordic countries to a underfloor heating pump and temperature management unit. Emmeti UK call this the T3 Control Set.
Can a T3 Control Set be fitted to a standard non inverted Topway Type 2 manifold? No, because-
- This would cause noise in the manifold valves fitted with an Electrothermic head because the flow would be in the wrong direction
- Flowmeters, where fitted, would not work accurately as the flow would be in the wrong direction
Both new and replacement systems (a system where a new boiler is fitted is classed as a replacement system) are required by the Building Regulations
1 to be thoroughly cleaned and flushed and a water treatment inhibitor added to protect the system from further corrosion. This is also particularly important where an underfloor heating (UFH) system is added to an existing heating system, to prevent the new UFH system becoming contaminated by water in the older system which may be contaminated with corrosion sediment. For further details of how to do this consult the following guides and code of practice:
- Domestic Building Services Compliance Guide
- BS 7593 – Code of practice for treatment of water in domestic hot water central heating systems
- BSRIA Guide BG29/2012 - Pre-Commission Cleaning of Pipework Systems
- BSRIA Guide BG 4/2011 – Underfloor Heating and Cooling
Yes but we only cater for 10mm and 15mm pipe
