How to Wire a Modulating Actuator as an On/Off Actuator
Are you trying to find out how to wire a modulating actuator for on/off? In this blog post, Brian Parks and Christian from Belimo Technical Support provide step-by-step instructions on how to do just that. They explore two wiring configurations for different types of actuators, with instructions applicable to both non-spring return and spring return units. With their guidance, learn how to correctly wire an actuator for on/off functionality. So keep reading to learn more about this important topic!
When wiring a modulating actuator for On/Off function, you typically use two types: a Non-Spring Return, and a Spring Return actuator. Both types require the same basic wiring with a transformer, black wire connected to common, and red wire connected to 24 volts hot transformer.

Non-Spring Return
- White wire connected to the control output of a 2-10V output signal
- Orange wire to Feedback (optional for position monitoring) Spring Return
- White wire connected to the 24 volts hot
- Orange wire (optional) disconnected, or tied off
Both types of actuators have the same functionality when wired for On/Off. When 24V is applied, the actuator fully powers open. When 24V is removed or zero volts is received, the actuator drive will then close. For the spring return actuator, it will fail to open or close depending on the application requirements. Depending on your application you may also want to connect the feedback wire.
As seen in the YouTube video, wiring a modulating actuator as an on/off actuator is not a difficult process. With the right information and tools, it can be done quite easily. As explained in the video, there are two ways to wire a modulating actuator, depending on whether it is a spring return or non-spring return model. It is important to make sure that the correct wires and connections are used. With this guide, we hope you have a better understanding of how to wire a modulating actuator for on/off applications.
