Night Light
The LED on the ZDW120 will by default, turn ON when the load attached is turned ON. To make the LED turn
ON when the load attached is turned OFF instead, set parameter 3 to a value of 1.
• Parameter No: 3
• Length: 1 Byte
• Valid Values = 0 or 1 (default 0)
Invert Switch
To change the top of the switch to OFF and the bottom of the switch to ON, set parameter 4 to 1.
• Parameter No: 4
• Length: 1 Byte
• Valid Values = 0 or 1 (default 0)
Ignore Start Level When Receiving Dim Commands
The ZDW120 can be set to ignore the start level that is part of the dim command, regardless
of whether the
command itself is telling the dimmer to ignore the start level or not ignore the start level embedded in the
command (see Parameter 1). Setting parameter 5 to a value of 0 will cause the ZDW120 to dim or brighten
from the start level embedded in the command.
• Parameter No: 5
• Length: 1 Byte
• Valid Values = 0 or 1 (default 1)
Adjusting Dim Rate
There are 3 sets of parameters that can adjust the dimming rate of the ZDW120.
1. One set to control how fast the dim rate is when the dimmer receives a Z-Wave command,
excluding ALL ON or ALL OFF command (Parameter 7 and 8).
2. One set to control how fast the dim rate is when the dimmer is locally controlled (Parameter 9 and 10).
3. One set to control how fast the dim rate is when the dimmer receives an ALL ON or ALL OFF command
(Parameter 11 and 12).
These values can be changed instantly to allow various scenes and effects.
The first of these parameters is the “dim step” (dim rate) parameter. It can be set to a value of 1 to 99. This
value indicates how many levels the dimmer will change when the timer (discussed below) expires.
The second parameter is the timing (how fast the dim rate) parameter. It can be set to a value of 1 to 255.
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 10 mS the dim level will change. If you set it to 255, then every 2.55 seconds
the dim level will change.
With the combination of the two parameters that can control the dim rate, the dimmer can be adjusted to dim
from maximum to minimum, or minimum to maximum at various speeds between 10 millisecond and 252.45
seconds (over 4.25 minutes).
