1 Location (Single Pole)
2 Locations (3-Way) with a toggle switch
2 Locations (3-Way) with Maestro companion switch (MA-AS)
3 or more Locations (4-Way) with Maestro Companion Switches (MA-AS)
Maestro Companion  Switch (MA-AS) for 3-Way or 4 Way applications sold separately. Note: The MS-Z101 will not work with MA-R companion dimmers.

Section (2):  FAQs
  • Do I have to use a companion switch in a 4-way (three locations) application?
Yes, a Maestro  companion switch (model MA-AS) must be used with the MS-Z101 for a 4-Way application.
  • How does a Maestro wire in a 4-way if there are only 3 terminals?
In a 4-way location, two wires will be connected to the blue screw terminal. These will be the wires that are tied to the blue screws on the other two dimmers.
  • Can I use two Maestro sensors in a 3-way application?
No. You can use only one sensor in a 3-way. You'll need to use either a mechanical switch or a Maestro companion switch (model MA-AS) in the other location. For 4-way applications, you'll need to use two Maestro companion switches with the sensor; you won't be able to use mechanical switches.
  • Can I run the low-voltage wire in the same conduit as the line voltage wire?
This answer depends on local codes and the capabilities of the ballast/driver. Local codes that allow Class 2 wiring to be run as Class 1 will call out what is required for reclassification, such as adding Class 1 labels over the Class 2 markings. However, running the 0-10 V signal as Class 1 wiring does introduce some concerns, including noise/interference caused by coupling between the line voltage and low voltage wires. This noise/interference can cause a voltage fluctuation on the 0-10 V wires which can create a difference between the light level requested by the control and the light level signal being received by the ballast/driver.
