GM VJ mixing unit for heating and cooling in floor/ceiling/wall systems. The supply water temperature is controlled by a mixing valve managed by a 24V actuator with 0-10 output signal. The module also contains an electronic circulation pump with variable flow-rate and head, ensuring high efficiency and very low power consumption. It also includes two shut-off valves provided with flow and return thermometers, PPE insulating shell and check valve to avoid bacterial diffusion. The mixing unit can be mounted in series on wall manifolds. It can be used in combination with RDZ WI controllers. • Pump centre distance: 125 mm • Max. temperature: 95 °C • Max. working pressure: 8 bar • Electric supply: 230V- 50 Hz • Size (wxhxd): 250x400x210 mm • Weight (DN 25): 5.4 Kg • Weight (DN 32): 5.7 Kg
