Belimo How-To: Commissioning 3-way control BFV

With the commissioning workflow for PR actuators, application-dependent, predefined settings can be selected easily and quickly and then written to the actuator. For the use as a 3-way control butterfly valve, the necessary parameters can be adjusted in just a few steps using the commissioning workflow. The adjusted parameters include the reduction of the maximum position (opening angle) to 60% and setting a linear characteristic curve to provide a constant mixing curve. The use as a 3-way control butterfly valve requires the commissioning of two devices. The control signal of the second actuator is automatically inverted using the commissioning workflow for parametrisation. The use as a 3-way control butterfly valve and a linear characteristic curve are only possible in combination with Belimo butterfly valves and are unsuitable for retrofit applications.
