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.
Invert Switch
• Parameter No: 4
• Length: 1 Byte
• Valid Values = 0 or 1 (default 0)
To change the top of the paddle to OFF and the bottom of the paddle to ON, set parameter 4 to 1.
Ignore Start Level When Receiving Dim Commands
• Parameter No: 5
• Length: 1 Byte
• Valid Values = 0 or 1 (default 1)
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.
Don’t Send Level Command After Transmitting Dim Commands
• Parameter 6
• Length: 1 Byte
• Valid Values = 0 or 1 (default 1)
When you press and hold the bottom of the ZDW120 paddle once, the Z-Wave devices that are associated into
Group 1 are sent the Dim command. After you release the paddle, the ZDW120 follows up by commanding the
devices to go to the same level of the ZDW120. By default, the ZDW120 is set not to do this. To enable ZDW120
to do this set this parameter to 0.
Adjusting Dim Rate
• Parameters 7-12
• Length: 1 Byte
• Valid Values: (See below)
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
max to min or min to max at various speeds between 10 millisecond and 252.45 seconds (over 4.25 minutes).
On/Off Command dim rate (excluding ALL ON/ALL OFF commands)
Parameter 7 Dim step Parameter (default = 1)
Valid Values: 1-99
Parameter 8 Dim timer Parameter (default = 3)
Valid Values: 1-255
