The LED on the ZTW230 will by default, turn ON when the status of the devices in Group 1 is ON. To make the
LED turn ON when the status of Group 1 is OFF set this parameter to a value of 1.
Invert Switch
• Parameter No: 4
• Length: 1 Byte
• Valid Values = 0 or 1 (default value is 0)
To change the top of the transmitter to OFF and the bottom of the transmitter to ON, set parameter 4 to 1. To
change back to original settings, set this parameter to the value of 0.
Ignore Start Level When Receiving Dim Commands
• Parameter No: 5
• Length: 1 Byte
• Valid Values = 0 or 1 (default value is 1)
Note that this only affects a level that is reported or possibly sent by the ZTW230 since the ZTW230
does not control a load.
The ZTW230 can send Dim commands to Z-Wave enabled dimmers. The Dim command has a start level
embedded in it. A dimmer receiving this command will start dimming from that start level. However, the
command can be sent so that the dimmer ignores the start level and instead start dimming from its current
level. By default, the ZTW230 sends the command so that the dimmer will start dimming from its current dim
level rather then the start level embedded in the command. To change this, simply set the configuration
parameter above to 0.
Adjusting Dim Rate
• Parameter 7-12
• Length: 1 Byte
• Valid Values: (See next)
Note that this only affects a level that is reported or possibly sent by the ZTW230 since the ZTW230
does not control a load.
For example: There are 3 sets of parameters that can adjust the dimming rate of the ZTW230.
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.
2. One set to control how fast the dim rate is when the dimmer is locally controlled.
3. One set to control how fast the dim rate is when the dimmer receives an ALL ON or ALL OFF command.
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 10mS 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 minutes).
On/Off Command dim rate (excluding ALL ON/ALL OFF commands)
• Parameter 7
• Dim step Parameter (default value is 3)
• Valid Values: 1-99
• Parameter 8
• Dim timer Parameter (default value is 10)
• Valid Values: 1-255
