Dimmers controlled by this switch will start dimming from their current level. Disable transmitting commands to Z-Wave devices that are in Group 4 without disassociating those devices from the group. In night-light mode the LED on the switch will turn ON when the switch is turned OFF. Change the top of the switch to OFF and the bottom of the switch to ON. Note: If you invert the switches and also install the product upside down, remember the load will now be controlled by the right, not the left switch. This dimmer will start dimming from its current level. When you press and hold the bottom of the ZDM230 switch once, the Z-Wave devices that are associated into Group 1 are sent the Dim command. If this parameter is set to "Yes" the devices in Group 1 will not go to the same level as the ZDM230. Indicates how many levels the dimmer will change for each dimming step. This value indicates in 10 millisecond resolution, how often the dim level will change. For example, if you set this parameter to 1, then every 10ms the dim level will change. If you set it to 255, then every 2.55 seconds the dim level will change. Indicates how many levels the dimmer will change for each dimming step.

If you set it to 255, then every 2.55 seconds the dim level will change. Units in Group 4 only track when the dimmer is being turned ON and OFF and not while dimming. The ZDM230 can operate shade control devices via its group 2. The ZDM230 can operate shade control devices via its group 3. The ZDM230 will flicker its LED when it is transmitting to any of its 4 groups. This flickering can be set to not flicker at all, to flicker the entire time it is transmitting, or to flicker for only 1 second when it begins transmitting. Poll Group 2 Interval Poll Group 2
