Hi,

I have a few of the newer dual-band KeypadLinc devices which support a 'Detach Load' feature, and whose load control I have no use for. In other words, they are not connected to any lights, they are just there for the buttons themselves.

I use HomeSeer 3 and the mnsandler plugin supports this 'Detach Load' feature. I use 8-button configuration and the A button is linked to a different Insteon device.

My question is, would enabling detach load have any affect on the longevity of the KeypadLinc by NOT ever engaging the triac (on a dimmer) or the relay (on an on/off switch)? I am only using the dimmer KeypadLincs in these situations. Do triacs even do any work if they are turned on but have no load attached?

Just wondering if I should bother enabling this feature on these KeypadLincs given their use situation, and if I would get any benefit from doing so.

Thanks for any input!

More than likely not. Generally, unless you're using an incompatible device, it'll be something else that goes out (usually capacitors).

My guess is that it would prolong the life of the dimmer, but since you are not using it, I do not think that you would see any impact. The only other advantage would be safety, even if the wire nut came off it would not matter.

Nearly all reported problems have been with the power supply (capacitors). As long a power is applied, the device is in use.

Thank you all for the feedback. I understand the device itself is always powered and that other components can fail which are completely separate from load control. I would think an on/off keypad with a mechanical relay would definitely benefit from this feature in this situation due to the wear and tear on the moving parts of the relay. I know nothing about triacs, though, and don't know if they actually do any work if the circuit isn't complete, or even if triacs can wear out. Does anyone know anything about that?

The triacs are engaged whether they are used or not. Since there is no load it does not matter.

As mentioned by all, generally the triacs don't go bad anyway (unless am incompatible lead is used). Most times, when a device goes bad its the capacitors.
