Question 3 way and a dimmer, need clarification

Guy's I need a little clarification on this item.

Customer comes in to buy a 3 way dimmable switch to replace only one of the non-dimmable switches. Wants to know if the non-dimmable will bring light to full brightness if the dimmable is off or partially in a dimmable mode.
My educated guess was yes it should, but I'm not sure.

No. whatever the dimmer is set to is what the non dimmer switch will turn it on to.
I find this very frustrating and only install three way dimmers with it's associated remote.

So if the dimmer is in the off position, the non-dimmer switch will not turn on the light?
What if two 3-way dimmer switches are used?

PS... the customer has no remote involved, just typical switches.

The non dimmer switch will still turn on the light but at whatever level the dimmer is set to.
so if you have the dimmer on minimum but off when you switch on the non dimmable switch, the lights will go to minimum.

No.... 2 three way dimmers is no better. If one dimmer is off.... the other one can't force it on.

I've been doing this a long time. I get customers asking me to install a three way dimmer and using the other existing three way switch..... it just doesn't satisfy and doesn't always work. Recommend to the customer to get a dimmer and it's matching companion. I keep a Lutron Maestro dimmer and it's matching companion on hand.

In the link is the incandescent kit. They also offer an LED/CFL model. In my opinion..... based on using them specifically...... this is the best three way dimmer package. The LED/CFL model works well with ALL bulbs.

Thanks Pete. I'm sure the customer will return the switch then I'll explain to him what you taught me. I have the Caseta but I never used the Maestro.

The Caseta should be a very similar setup.

Hey, Pete, thought you might like to know. Customer came in yesterday and returned the switch. He said he was too unsure of himself to even attempt the swap out. So I told him I did some investigation with experts and explained that it would not work anyways.
Thanks again for the info.
