Problem with 8 button Keypad 2334-222


Recommended Posts

I recently replaced a 8 button Inseton keypad 2486 with the new Insteon 8 button keypad 2334-222 because the LED's would not illuminate despite setting the LED brightness level to 15 in the ISY admin console. I have since spent some time searching the forum and investigating the symptoms of this problem. The interesting part is that button A is assigned as a controller for a floor light which is set at a "on level" of 98% (to reduce voltage to light and save the bulb a bit). When I set the LED brightness for the keypad in the admin console to 15 and operate button A the LED comes on when pressed and goes off when pressed again, just as is should. I operated it multiple times and the LED comes on and off just as it should. Now Button B is assigned as a controller for a scene called "Movie Scene" the "Movie Scene" turns on two lights, both at 24% when I FIRST press button B after changing the brightness level in the admin console the LED backlight and the "Movie Scene" is activated, a second press turns off the "Movie Scene", the two lights and the LED backlight...now pressing it a third time activates the "Movie Scene" and the two lights but the LED backlight for Button B does NOT illuminate. Furthermore, when I return to the Admin Console to check the LED brightness it has reset to 0 for all buttons. I have done this several times (reset in Admin Console, press B button three times, LED Brightness resets to 0). I'm stuck, this functionality used to work with my old 8 button 2486 but when the 2486 quit working I replaced it with the new 2334-222 and the problem persists. What has changed? anyone have any ideas? Thanks in advance for the help!

First, the Backlight level cannot be set for individual buttons. Setting a Backlight value applies to all buttons. The newer devices use Backlight value as a % On rather than an Off/On value. An Off/On setting of 7/15 (0x7F) is 100% On. An Off/On value of 3/15 (0x3F) is approx 50% On level. An Off/On value of 0/0 turns the button LEDs completely Off. It does not logically turn the button Off, only the LEDs Off for those who want a dark KPL at night. Going from 0/0 to 7/15 will turn the LEDs back to the previous button LED On/Off state. That is, a button LED that was On before going to 0/0 will be On when going back to 7/15.

LeeG, thanks for your quick response. I did set the KPL to 7/15 using the admin console and in the OFF state all the buttons were lit. I pressed the "Movie Scene" which is on button B a couple of times and all the KPL buttons turned off and stayed off. Returning to the Admin Console I found that the LED Brightness was back to 0/0. I then reset it to 7/15 using the admin console and again found all buttons lit. I repeatedly pressed the "A" button (100% floor light on) and all the buttons stayed lit. I then pressed the "B" button and all the buttons went dark, returning to the admin console I found the LED Brightness in the Admin Console to be reset to 0/0. I don't understand what is resetting the LED brightness and why the brightness will not hold in the KPL, any ideas?

This sure sounds abnormal to me. Have you checked the keypad manual to determine how to manually set the backlight levels? Does it involve button B somehow? I wonder is there is some failure or stuck button on the keypad that is causing this.

I did play with trying to manually set the backlight level, involves tapping the C and F buttons and holing the A (or on button). I can set them locally but have the same issue. Wondering if the scene assigned to be toggled by button B has anything to do with this issue? the Button assigned to Scene B turns on two room lights at 24%. I'm stuck, any help appreciated.
