Question about 3-way behavior

[ds7771]

Hi, I have been using Insteon switches for a while, controlled by ISY994. However, I just had the opportunity to install my very first 3-way 2477D setup. The switches behave a bit differently than I am used to, and I am wondering if this is normal behavior:

 

assumptions

Box 1 = Line

Box 2 = Load

ISY scene programmed with both switches as controller/responder, with on-level set to 70%

 

Box 2 behaves like I would expect.

Single tap turns the light on 70%.

Subsequent single tap sets level 100%.

Subsequent single tap sets level back to 70%.

 

Box 1 is different.

Single tap sets level to 70%.

Subsequent single tap does nothing. Only a subsequent double-tap will set level to 100%.

Subsequent single tap sets level back to 70%

 

Is Box 1 behavior normal, or am I doing something wrong?

 

Thanks!

That is normal operation. Box 2 is directly controlling the load. First tap from Off turns it to the Local On Level. Next tap On goes to 100%, next tap to Local On Level.

 

Box 1 is not directly controlling the load. Turning On this device it goes goes to Local On Level. Next tap On goes to 100% On Level, next tap to Local On Level. No mention about whether this is a Dimmer or a Relay so I assumed a Dimmer. This device has the device in box 2 as a Responder. When an On command is sent to a Responder that device goes to the defined Responder On Level. The next On command goes to the same Responder On Level. As a Responder it always goes to the defined Responder On Level. The Local On Level does not participate. Local On Level controls what the device does when the local paddle/button is pressed. Local On Level has no affect on the Responder On Level information.

Makes sense, thanks for the explanation. I assumed this behavior was unique to the virtual 3-way switch, where box 1 is not connected to the load.

That is the way Scene Responders work. Take a look at the device User Guide in the area where the Local Ramp Rate is discussed. There are two modes of operation related to how the Local On Level works. Perhaps the other way would be better for you.
