Quick connection kit with 4-way mixer, for boilers 400 kW

Quick installation kits based on the Victaulic quick installation system are an elegant and technically complete solution for organizing the connection of the boiler to the heating system. Structurally made in metal, for the organization of a full and complete design of the boiler circuit. Further connection can be made with both steel and plastic pipelines. When working on a pellet burner, it is allowed to connect to the heating system without a heat accumulator or buffer.
Built-in 4-way mixing valve for preparing the temperature of the coolant, whether it is underfloor heating, a fan heater, a classic radiator heating system or non-standard systems - the required temperature of the coolant will be prepared exactly. Complete with automation of FOCUS boilers - regulation is carried out according to a weather-dependent algorithm.
Separate screw connections for organizing the connection of the DHW circuit complete the design of the quick assembly kit. What is included with the automation of FOCUS boilers - allows you to work both in DHW priority and without priority, both in winter and summer algorithms (when the boiler can only work on DHW).
