3 Product description 3.2 Function K33 - constant value control circuit 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. -
Page 7: 3-Way Mixing Valve With Bypass [Specialist]
3 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 3 Product description 1. During commissioning, determine the optimum bypass position for the operation of the installation through a trial-and-error process. If the slot of the bypass screw is in a vertical position, the bypass is closed (normal operation). If the slot of the bypass screw is in a horizontal position, the bypass is completely open.
