Product description 3.2 Function Controlled circuit with constant value 20-50 °C with 3‑way mixing valve and bypass 0-50% The flow temperature of the heating circuit is controlled by the integrated mixing valve. Hot water from the boiler and cold return water are mixed to obtain the desired flow temperature of the heating circuit. -
Page 7: 3-Way Mixing Valve With Bypass [Specialist]
Product description 3.2.1 3-way mixing valve with bypass [specialist] The 3-way mixing valve is a constant-value mixing valve for radiant panel heating systems (radiant floor heating, wall heating etc.) which are operated with a constant flow temperature and thus guarantee a basic heat supply. The desired flow temperature can be adjusted at the thermostatic head. - Page 8 Product description If the slot of the bypass screw is in a horizontal position, the bypass is completely open. A maximum flow rate from the return to the flow line is thus enabled. This adjustment may be necessary for radiant floor heating systems which require a very high water flow volume.
