Crestron DIN-1DIMU4 DIN Rail Universal Dimmer
DIN Rail Universal Dimmer:
DIN-1DIMU4
Introduction
The DIN-1DIMU4 is a four channel universal lighting control module
designed to support dimming of both forward and reverse phase type
loads. A single model supports both 120 and 220-240 Volt electronic and
magnetic low-voltage, incandescent, neon/cold cathode, 2-wire dimmable
fluorescent, and non-dimmable lighting loads up to 5 Amps per channel,
10 Amps total.
Features and Functions
• Four channels of forward or reverse phase dimming
• Auto load detection
• 120 to 240 Volt 50/60 Hz operation
• Selectable non-dim mode
• Extreme stability in noisy environments
• Short circuit and overload protection
• Master air-gap relay
• Override input
• Cresnet®communications
• Setup via front panel or software
• Programmable functionality via DIN-AP2
• 12M wide DIN rail mounting
Operations & Installation Guide – DOC. 6668D DIN Rail Universal Dimmer: DIN-1DIMU4 •1

DIN Rail Universal Dimmer Crestron DIN-1DIMU4
Auto Load Detection
Each channel of the DIN-1DIMU4 is capable of auto-detecting the
dimmable load type connected to it and selecting the appropriate
operating mode to control that load. Reverse phase (trailing edge) mode
supports incandescent and electronic low-voltage load types, while
forward phase (leading edge) mode handles magnetic low-voltage, neon,
and other inductive load types. A non-dim mode is also selectable for
switching of non-dimmable lighting fixtures. Any channel may be set for
any mode, allowing one dimmer module to handle any combination of
lighting types on four separately controlled circuits.
Phase-Synchronous Detection Circuitry
Crestron®proprietary zero cross filter technology provides superior
immunity to noise on the power line, reducing lamp flicker and
compensating for fluctuations in line voltage and frequency.
Short Circuit Protection
Built-in over current protection (OCP) prevents failure of the
DIN-1DIMU4 caused by excessive loading or improper wiring of the
outputs.
Master Air-Gap Relay
When all four channels are turned fully off, the internal master relay
automatically opens providing air-gap isolation to allow safe servicing
and changing of light bulbs on all four controlled circuits.
Override Input
An override input is provided to allow an external contact closure to
momentarily override the control system program and set each channel
output to its override preset level. Levels can be adjusted and saved
locally from the front panel, or remotely via software.
DIN Rail Installation
The DIN-1DIMU4 is designed to snap onto a standard DIN rail for
installation in a wall mount enclosure. Wiring connections are made
using screw terminals positioned along the bottom, clearly accessible
from the front for easy installation and servicing. All setup controls and
indicators are positioned on the center front panel. When installed in an
2 •DIN Rail Universal Dimmer: DIN-1DIMU4 Operations & Installation Guide – DOC. 6668D

Crestron DIN-1DIMU4 DIN Rail Universal Dimmer
enclosure utilizing 45 mm cutouts, the DIN-1DIMU4's front panel stays
accessible while the connections are concealed.
Cresnet®
The DIN-1DIMU4 communicates with a DIN-AP2 2-Series Automation
Processor, or other Crestron 2-Series control system, via the Cresnet
control network. A pair of Cresnet ports is provided on the DIN-1DIMU4
allowing for easy daisy chaining of several DIN Rail Series automation
control modules.
Applications
The following diagram shows a DIN-1DIMU4 in a typical application.

Setup
Network Wiring
When wiring the Cresnet network, consider the following:
• Use Crestron Certified Wire.
NOTE: Cresnet HP cannot be used.
• Use Crestron power supplies for Crestron equipment.
• Provide sufficient power to the system.
CAUTION: Insufficient power can lead to unpredictable results
or damage to the equipment. Use the Crestron Power Calculator to
help calculate how much power is needed for the system
(www.crestron.com/calculators).
• For networks with 20 or more devices, use a Cresnet Hub/Repeater
(DIN-HUB) to maintain signal quality.
For more details, refer to “Check Network Wiring”, which starts on page
28.
Identity Code
The Net ID of the DIN-1DIMU4 has been factory set to 86. The Net IDs
of multiple DIN-1DIMU4 devices in the same system must be unique.
Net IDs are changed on the front panel of the DIN-1DIMU4 or from a
personal computer (PC) via Crestron Toolbox™ (refer to “Establishing
Communication” on page 21).
To set the Net ID using the front panel:
1. Press the SETUP button to enter the Setup mode. The SETUP
LED illuminates.
2. Press the left button under the NET ID display to change the most
significant digit of the Net ID or press the right button under the
NET ID display to change the least significant digit of the Net ID
number.
Operations & Installation Guide – DOC. 6668D DIN Rail Universal Dimmer: DIN-1DIMU4 •11

DIN Rail Universal Dimmer Crestron DIN-1DIMU4
3. When the desired Net ID is displayed, press the SETUP button to
exit the Setup mode. The SETUP LED extinguishes.
NOTE: If an invalid Net ID is set (e.g., 00, 02, FF), “Er” will be
displayed on the NET ID display. The DIN-1DIMU4 will revert to the
previously set Net ID.
NOTE: The DIN-1DIMU4 will leave the Setup mode after 10 seconds
of inactivity. The DIN-1DIMU4 will revert to the previously set Net ID.
NOTE: A small label (with numbers and letters) is provided on the front
panel of the DIN-1DIMU4 to document the unit’s Net ID in the case
where power is not available. Apply a mark over the digits that
correspond to the assigned Net ID.
NET ID Label (“3C” Shown)
When setting the Net ID, consider the following:
• The Net ID of each unit must match an ID code specified in the
SIMPL™ Windows program.
• Each network device must have a unique Net ID.
For more details, refer to the Crestron Toolbox help file.
Installation
The DIN-1DIMU4 must be installed by a licensed electrician, in
accordance with all national and local codes.
CAUTION: This equipment is for indoor use only. Mount in a well
ventilated area. The ambient temperature must be 0º to 40º C
(32º to 104º F). The relative humidity must be 10% – 90%
(non-condensing).
NOTE: When installing in an enclosure, high-voltage devices should be
grouped separately from low-voltage devices.

Top
1. Use a flat object (e.g., a flat head screwdriver) to pull the DIN rail
release downward.
2. With the top of the unit tilted toward you, place the DIN-1DIMU4
against the bottom of the DIN rail.
NOTE: When mounting DIN rail products, it may be necessary to
use a flat-head screwdriver to pull the DIN rail release tab while
snapping the device onto the DIN rail.
3. Tilt the top of the DIN-1DIMU4 toward the DIN rail until it is
secure on the top edge of the rail. Push the DIN rail release upward
to lock the DIN-1DIMU4 into place.
To remove the DIN-1DIMU4 from the DIN rail, use a small, flat object
(e.g., a flat head screwdriver) to pull the DIN rail release downward to
unlock it and tilt the top of the DIN-1DIMU4 away from the DIN rail.
NOTE: Certain third party DIN cabinets provide space for an
informational label between each DIN rail row. Crestron Engraver
software (version 4.0 or later) can generate appropriate labels for all
Crestron DIN rail products.

WARNING: Prior to connecting the device, turn off power at the circuit
breaker. Failure to do so may result in serious personal injury or damage
to the device. Restore power after all connections have been made.
CAUTION: Connecting this device to the wrong type of load or
short circuiting the load can cause severe product damage. Each load
should be tested to identify a short circuit condition prior to wiring the
load to the module.
NOTE: Install in accordance with all local and national electric codes.
NOTE: High-voltage connections accept 2.5 mm2(12 AWG) wire. Wire
should be stripped to 8 mm (1/3 inch). Tighten terminal blocks to 0.5 Nm
(5 in-lbs).
NOTE: Use copper wire only. For high-voltage connections, use wire
rated for at least 75º C (167º F).
NOTE: The DIN-1DIMU4 power feed must be protected by a 10 A (trip
curve C) breaker or equivalent.
NOTE: The DIN-1DIMU4 outputs must be used for control of
permanently installed lighting loads only.
