Unlink the "dedicated" off/on buttons on the 2487S from the internal switch

[Andy Wylde]

Does anyone know if it is possible to unlink the "dedicated" on/off buttons on the 2487S? 

The reason I would like to do this is that I am controlling a 2475 FanLinc with it (among other things.  It would just be really nice if the big off/on buttons could control the dimmer for the light in the fan via the 2475 (the main room light).  I would just wire the light directly to the 2487, but there is no dimming function.   I have the output of the switch itself wired to another motor which rotates the fan assembly (it has multiple fans attached to a rotating assembly). 

I have the big buttons control the light dimmer, but it also turns on or off the rotation. 

Even if this is not possible I would appreciate knowing that so I don't waste any more time.

Thanks in advance,

Andy

I’m making a lot of assumptions to help you think through based on what you’ve written but would need a wiring diagram to understand layout and maybe suggest a solution. If you don’t fully understand the process then get an electrician. That said...

Think through putting a wire nut on the red load wire of the 2487S which effectively unlinks it from direct control of anything.

Run wires to the FanLinc so it’s always got power (wired hot). In 2487S switch box,the hot black wire coming in with power wired to black (line) on switch and to black wire going out of box to the fanlinc electrical box. Same logic for white wire but on 2487S white wire is marked as neutral. These wires would be wired to fanlinc neural and line wires giving it power all the time. You might use scenes linked to buttons on the 2487S to control the fan and it’s light. Lastly sounds like you could create a scene including switch from overhead lights, 2487s, and fanlinc lights node to have them be in sync on lighting.

Again, NOT offered as a solution. Just something to aid you in thinking it through.

It sounds like you've connected the 2487 to the fanlinc directly which is the incorrect way to wire it when used in connection with the fanlinc. 

Hart2hart's explanation is what you need to do in order to accomplish what you're trying to do. 

Once re-wired, you'll be able to link the light to the buttons for control and control the speeds separately. You'll also be able to dim the fanlinc from the big buttons as well.

Thanks. To OP, you need to closely read how to setup fan speed scenes with keypadlinc buttons A-D. It was far from intuitively obvious to me.

Thank you for your replies.  I do indeed have power run to the switch and fan -- they are not directly connected.   The issue as you point out is that I was wanting to use the 2487 to turn on or off the assembly rotation, which by default is the large buttons and as I understand it that is not going to change, although they can be programmed with a scene to do other things like dim the light.   I have programmed it as mentioned above and it works, but I can't control the assembly rotation without adding another relay.   Or I can program the other buttons and use the output from the 2487S to turn off and on the light, but no dimming because it is an S.   After reading your replies and testing various configurations I have ordered a 2487D and will use the output of it to power the light and program the smaller buttons to operate the FanLinc for the fan itself and the rotation, using the light output to power the rotation.  

And yes, I read the instructions about 4 times for the buttons before I got it right.  I read several other ways to do it which were overly complicated.  I am happy with how it controls the fan speed now.  Its just this other motor which makes it unlike most fans that throws everything for a loop.

Thank you again.

Is the red wire on the 2487s capped off? 

As mentioned in my previous reply; you CAN dim the fanlinc from the 2487s.

Glad it’s working for the most part. I’m still not completely clear on the other motor. If there is something independent that you want to control, maybe a micro module could be wired in to control it as part of a scene. Depending on space you might be able to hide a relay with button or inline relay (think someone posted they were out of stock) if amps exceeds a micro module. Also, as lilyoyo1 stated, the 2487S will dim as part of a scene but not when directly wired. Was odd to me too.

I'm not clear on the other motor as well. What kind of fan is it? Make/model

[PurdueGuy]

The quickest answer is, as far as I know, the on/off on the keypad are directly tied to the "load" output from the switch.

They cannot be decoupled.

As I am reading the OPs original post:

Wiring:

• FanLinc input wired to Hot
• 2487S (KPL) input wired to HOT
• FanLinc:
  • Light output wired to fan light.
  • Motor output wired to fan motor.
• 2487S load (red) wired to secondary fan assembly that rotates fans.

Desires:

• KPL On/Off BUTTONS control fan light via FanLinc
• KPL scene button (A/B/C/D) control fan motor via FanLinc
• KPL load (red) controls rotation assembly motor

The short answer is: no, I don't think you can do this with 1 FanLinc and 1 2487S.  The KPL On/Off button will always control the load.  You can have the load go nowhere, but you can'y decouple them.   It would be great if I am wrong though.

I am guessing it is some setup like this.  (In this example there is no secondary motor to spin the fans, but doing do would be easy.  This example just spins them based on the fans moving air themselves.

I think your best bet is to cap the KPL load wire and use a secondary Insteon device (micro module, etc. as suggested) to control the second motor with an ISY program based on Fanlinc status.
