Function 

The mixing group GM 1192 is a regulation group which combines a 
number of components in a single device able to maintain a pre-set 
temperature in the radiant panels circuit of mixed heating systems. The 
temperature in the panels is kept constant by a regulating valve which 
mixes hot water coming from the boiler with the low temperature one 
circulating in the panels. The GM 1192 can be connected directly to 
Luxor manifolds for radiant panels by means of a G 1” male fitting with 
soft seal. This makes the GM 1192 particularly convenient, since 

it can be kept in stock as a modular component.  

Moreover, the GM 1192 makes mixed heating systems extremely 
flexible, since the regulation group can be adjusted to meet the future 
requirements of the secondary circuit. It is therefore possible to expand 
the radiant panels system simply by adding outlets, without temperature 
or pressure issues downstream of the group. 

The GM 1192 can be set both to increase the heating capacity 

and to balance pressure drops. 

Finally, thanks to its great regulation capacity, the GM 1192 allows to 
make the secondary circuit independent from the primary in case of 
replacement of important parts of the system, for example when a new 
boiler with a different operating principle is installed. By means of the 
bypass circuit, the circulation pump can keep on operating at design 
conditions. 

This type of system can supply a max thermal power of 20 kW with a 
temperature of the primary circuit of ≥ 70°C.
