Operation
NOTE: Before using the HZ-KPEX, ensure the device is using the latest
firmware. Check for the latest firmware for the HZ-KPEX at
www.crestron.com/firmware. Firmware is loaded onto the device using
either Crestron Toolbox™ software or Crestron Home™ software.
Disconnect the Power
Power to the keypad buttons, LEDs, and the connected load(s) can be
disconnected by using the air-gap switch, which is located at the bottom
of the device. Slide the air-gap switch to the right to disconnect the power
to the device buttons, LEDs, and to the connected load(s), and slide the
switch to the left to restore power.
NOTE:
lWhen the air-gap switch is in the right position, power is still supplied
to the HOT terminal of the device.
lThe switch must be in the left position for the device to operate.
Default Button Functionality
The figure below illustrates the press and hold actuation sequences for
each local button option as selected in programming. There is only one
local button available per device. The HZ-KPEX can be used as a multiway
controller. When using the device as a multiway controller, the local
button that controls the master load controller must be selected.
Button behavior can be altered by the control system program. If the local
button is disabled in the control system program and communication to
the control system is lost, the device will default to the shown behavior.
When enabled, the local button can still act as a remote trigger. However,
LED feedback for the local button will be dictated only by the On/Off
state of the master load controller. When the HZ-KPEX is not used as a
multiway controller, the local button should be disabled in programming.

LED Behavior
The LED on the local button of the HZ-KPEX (if enabled) displays the
state of the remotely controlled device’s load. The LED behavior described
here only pertains to the local button. All other LEDs are controlled in
programming. The LED used for local feedback cannot be controlled
remotely.
Each LED can be in one of the following states:
lOn: The load is powered.
lOff: The load is not powered.
NOTE: LED functionality for both local and remote behavior can be
modified when programming the device.
Wireless Communications
The device connects to the Crestron network via the infiNET EX
communications protocol. Use the following procedures to join or leave an
infiNET EX network and to verify communications between the device and
the control system.
NOTE: The HZ-KPEX is not compatible with the MC3 internal gateway
when using channels 25 or 26.
Joining an infiNET EX Network
Before a device can be used in a lighting system, it must first join an
infiNETEX network by being acquired by an infiNETEX gateway.
NOTE: A device can be acquired by only one gateway.
1. Put the infiNET EX gateway into Acquire mode from the unit itself or
from Crestron Toolbox software, as described in the gateway’s
manual at www.crestron.com/manuals.
NOTE: In an environment where multiple gateways are installed,
only one gateway should be in Acquire mode at any time.
2. Place the device into Acquire mode.
a. Tap the top button three times, and then press and hold it down
(tap-tap-tap-press+hold) until all of the LEDs flash red once
(this can take up to 10 seconds if the device has been previously
acquired to a gateway).
NOTE: If a side-to-side rocker is in the top position, either
side of the rocker can be pressed and held.

b. Release the button to start the acquire process. The top
button’s LED flashes red slowly to show that the device is
actively scanning the infiNET EX network.
lThe top button’s LED lights red for 5 seconds to show
that the device has been successfully acquired to the
infiNET EX network.
lThe top button’s LED flashes red quickly to indicate that
the device was not successfully acquired by the infiNET
EX network. Tap the setup button to acknowledge failure
to acquire the infiNET EX network. Before attempting the
acquire process again, ensure one of the following:
oThe gateway is in Acquire mode and within range.
oA non-battery powered infiNET EX device is in Acquire
mode on the same gateway.
3. Once all devices have been acquired, take the gateway out of Acquire
mode. Refer to the gateway’s manual for details.
Leaving an infiNET EX Network
To leave an infiNET EX network, put the device into Acquire mode. Ensure
that no gateway is in Acquire mode when removing a device from an
infiNETEX network.
To place a device into Acquire mode, refer to step 2 in Joining an infiNET
EX Network.
Verifying Communications Status
To check the communications status of the device, tap the top button
three times and then press and hold it down (tap-tap-tap-press+hold) for
up to 2 seconds. The button must be released before the LEDs flash to
indicate the communications status. Refer to the following table for
details.
NOTES:
lIf a side-to-side rocker is in the top position, either side of the rocker
can be pressed and held.
lIf there is a communication error and a remote button is pressed, all
of the LEDs will flash red in one of the patterns described in the table

Ambient Light Sensor Calibration
An LED backlight behind each button illuminates engravings. The ambient
light sensor adjusts the backlight brightness according to the light level in
the room. The ambient light sensor can be affected by room conditions
and should be calibrated manually (locally or through programming), or
the appropriate setting can be changed in control system programming.
To locally calibrate the light sensor:
1. Ensure that all room lights are fully on.
2. Ensure the faceplate and bottom trim piece are installed correctly.
Remove the top trim piece.
3. Press and hold the setup button with a small pointed object for about
2 seconds until all keypad backlights flash magenta. This can also be
triggered in programming.
4. Avoid blocking the light sensor on the bottom of the HZ-KPEX. The
light sensor should remain unobstructed and free of direct light. After
about 5 seconds, the calibration process is complete. The keypad
returns to normal operation.
Backlight Customization
Backlight color customization can be accomplished locally or through
programming.
NOTE: Custom and preset color themes may be defined in the control
system program. Custom programming will override local settings.
To locally change the color of the LED backlights:
1. Press the setup button with a small pointed object once. The LED
backlights will light brightly for 15 seconds.
2. Press the setup button repeatedly to cycle through the backlight color
options.
