2.2 Wiring
WARNING! DO NOT ALLOW THE YELLOW WIRE
OR +24V TERMINAL ON THE ULTRA-AIRE DEHUMIDIFIER
TO COME IN ELECTRICAL CONTACT WITH THE RED/WHITE
WIRES OR COM/DMPR TERMINALS ON THE ULTRA-AIRE
DEHUMIDIFIER OR DAMAGE TO THE TRANSFORMER WILL
RESULT.
WARNING! THE REMOTE CONTROL OF THE
ULTRA-AIRE DEHUMIDIFIER OPERATES ON A LOW VOLTAGE
CIRCUIT (24 VAC) AND MUST NEVER CONTACT OR BE
CONNECTED TO A HIGH VOLTAGE CIRCUIT.
WARNING! UNPLUG THE ULTRA-AIRE
DEHUMIDIFIER BEFORE WIRING THE DEH 3000R.
The installer must supply all field wiring, including the wiring
between the Ultra-Aire dehumidifier and the DEH 3000R. Some
of the control wires or terminals on the dehumidifier may not be
used in some control situations and should be left disconnected
with wire nuts taped onto the stripped ends (if necessary).
Be sure to consult the electrical schematic in this manual or
the internal electrical box of the Ultra-Aire dehumidifier before
making any control connections.
WARNING! ONLY CONNECT THE DMPR
TERMINAL TO THE CONTROL IF IT IS WIRED IN A
CIRCUIT THROUGH AN ELECTRIC DAMPER, OTHERWISE
TRANSFORMER DAMAGE MAY RESULT.
The White wire controls the optional motorized damper
that can be installed into a fresh air duct. This damper
provides the ability to control fresh air ventilation using
the ventilation timer function of the DEH 3000 and the
terminal labeled “DMP” on the DEH 3000 (See Section
3.8). Leave the “DMP” terminal unused if a motorized
damper is not used, and cap off the White wire from
the Ultra-Aire dehumidifier.

3.5 Adjusting the Relative Humidity “SETPOINT”
The DEH 3000R senses the ambient relative humidity (%RH) of
the space where the remote sensor is located. It comes factory
preset to hold 50% relative humidity.
6
DEH 3000R Dehumidifier & Ventilation System Controller Installation, Operation & Service Manual

The relative humidity “SETPOINT” (desired RH to be
maintained) operates the dehumidifier function of the Ultra-Aire
dehumidifier. It has no effect on the optional VENT (fresh air
ventilation) or FAN (household air recirculation) functions if they
are being used.
Operation
The standard range that the dehumidifier holds around your
“SETPOINT” is 3%. With a setpoint of 50%, the dehumidifier
will run until the relative humidity reaches 47%. The
dehumidifier will then switch off until the relative humidity
reaches 53%.
If the setpoint is higher than the ambient relative humidity, the
space does not need to be dehumidified, so the dehumidifier
will not run.
Example: Setpoint: 50% RH
Current condition: 45% RH –The dehumidifier will be off (no “O”
indicator will be displayed).
If your setpoint is below the ambient condition, the dehumidifier
will be on and “O” will display.
Example: Setpoint: 50% RH
Current condition: 55% RH –The dehumidifier will be on (“O”
displayed).
3.6 Temperature Cutout Programming
Dehumidifiers produce heat when dehumidifying and depending
upon outside conditions, the ventilation function may also
introduce warm air. Some conditions may introduce enough
heat to drive household temperatures up. The DEH 3000R
temperature cutout feature disables all Ultra-Aire operations if
household temperatures reach the cutout setpoint.
In most installations this feature will not need to be used (the
cutout is factory set to 99°F). If a lower temperature cutout
is desired, program the setpoint by pressing and holding the
“PROGRAM ENTER” button until the “PROGRAM” screen
appears. Press the up/down “RH” buttons until “TEMP
CUTOUT” highlighted. Then press the “PROGRAM ENTER”
button again to select it. Now use the “RH” up or “RH” down
buttons to adjust the setpoint. Press “PROGRAM ENTER” to
return to the home screen.
Personal Settings Reference List

SETPOINT (%RH) 50%
VENT Closed
FAN Auto
TEMP CUTOUT 99°
3.7 Fan Setting and Operation
Use the “FAN” button to change the fan operation. There are 2
choices for fan operation: “ON” or “AUTO”. The factory preset
is “AUTO”.
“ON” –The fan in the Ultra-Aire dehumidifier will run
continuously. This does not affect either the dehumidification
or ventilation functions of the system. The system may or may
not be ventilating or dehumidifying while the fan is running. This
setting is commonly used for maximum air filtration and/or air
recirculation.
“AUTO” – Indicates the fan will run when the DEH 3000R calls
for dehumidification or ventilation. If the control has not called
for dehumidification for 3 hours, the control will automatically
run the dehumidifier fan for 10 minutes.
After a dehumidification cycle, the fan automatically shuts off
for 10 minutes. This pause allows the water to drain from the
dehumidifier.
A solid “O” indicates the fan is operating. A flashing “O”
indicates the fan is in a wait mode. No “O” indicates the fan is
OFF.
To set the operation:
1. Press and hold the “FAN” button. The current fan setting will
begin to flash on the display. Release the button.
2. Press the “FAN” button to toggle between the “ON” and
“AUTO” modes.

DEH 3000R Dehumidifier & Ventilation System Controller Installation, Operation & Service Manual

With the fan in the “AUTO” mode, the fan will operate only
when needed by other functions of the system. The fan will
remain OFF unless the system is dehumidifying or ventilating.
The fan always runs during dehumidification and ventilation and
the fan “O” icon will be lit. To completely turn the system OFF,
use the “ON/OFF” button as described earlier.
3.8 Damper Operation and Ventilation,
Manual (Hold) Mode
The “VENT” setting controls the ventilation function of the
system. It has no control over the dehumidification function. In
order to provide ventilation, the motorized damper must be open
and the fan must be running. The controller takes care of these
two functions automatically so that whenever the damper is
open, the fan is running.
The ventilation indicator “O” will be displayed whenever the
unit is ventilating. The fan operation indicator “O” will also be lit.
There are three damper operation modes:
1. “OPEN” – hold mode: The damper will be open and the
dehumidifier fan will be continuously operating to introduce
fresh air into the space. Use this mode for continuous fresh
air ventilation. The fan is always on when the damper is open.
2. “CLOSED” – hold mode: The damper will never open, and
the dehumidifier will not ventilate. The fan will still operate
normally for recirculation and dehumidification.
3. “PROGRAMMED” mode: The DEH 3000R will operate the
motorized damper and the dehumidifier fan according to the
programmed ventilation schedule (Section 3.9).
The factory preset for the “VENT” setting is “CLOSED”.
To set “OPEN” – hold or “CLOSED” – hold ventilation
operation:
1. Press the “VENT” button. The current setting will begin to
flash on the display. Release the button.
2. Press the “VENT” button again to switch between “OPEN”
and “CLOSED”.
3. Leave the control alone for 10 seconds and your settings will
be saved.
3.9 Damper Operation and Ventilation,
Programmed Ventilation
This example shows the system in program mode (denoted by
the schedule 15 minutes on, 5 minutes off and the word RUN in
the lower right corner of the display).
The DEH 3000R will operate fresh air ventilation according to
your ventilation program. The control needs to be programmed
to turn the ventilation function ON and OFF at the desired
intervals. This is done by programming the ventilation timer.
There are two programs available for ventilation:
1. Monday through Sunday
2. Monday through Friday & Saturday/Sunday
Each block of days has a morning schedule and a night
schedule. Morning is the first 12 hours of the day and night is
the second 12 hours.
Each schedule has:
• A “START” time when the ventilation schedule begins,
• An “OPEN FOR” duration for the amount of time the damper
stays open in 5 minute intervals, from 0 to 60,
• And “CLOSED FOR” duration which closes the damper for a
specified time in 5 minute intervals from 0 to 60.
Setting the Ventilation Program:
1. Press the “PROGRAM ENTER” button until the following
menu appears:

“MON-FRI” “SAT-SUN” for separate weekday and weekend
schedules, or “MON-SUN” which gives you equal weekday and
weekend schedules.
3. Using the Up/Down “RH” buttons, highlight and then select
one of the two choices. The example given shows how to
program separate weekday and weekend schedules. The same
method is used if you choose the other program.
Example menu when you select “MON-FRI” “SAT-SUN”:
1. Enter the starting time for weekdays using the up/down “RH”
buttons to change the time.
2. Press the “PROGRAM ENTER” button to switch to the
“OPEN FOR” setting. Using the up/down “RH” buttons,
change the duration that the damper will ventilate fresh air.
3. Press the “PROGRAM ENTER” button to switch to the
“CLOSED FOR” setting. Using the up/down “RH” buttons,
change the duration that the damper will remain closed
between ventilation cycles.
For the example given, starting at 8:00AM in the morning, the
control will ventilate fresh air for 15 minutes then stop for 15
minutes. This schedule of 15 minutes open, 15 minutes closed
will continue until the start time of the night schedule.
Morning schedule is available anytime from 12:00AM until
11:59AM.
Night schedule is available anytime from 12:00PM until
11:59PM.
4. Press “PROGRAM ENTER” again to go to the “MON-FRI”
night schedule. Repeat the steps listed above for this and the
“SAT-SUN” day and night schedules.
When you have finished programming your schedule (either the
7-day version or the weekday/weekend split version), use the
down “RH” button to highlight the EXIT option and then press
“PROGRAM ENTER” to select it.

5.1 Remote Sensor Usage
IMPORTANT!
The use of spray paint on the sensor housing may damage
the sensor and is not covered by the product warranty.
The remote sensing option is used when an installation
requires mounting the DEH 3000R out of the conditioned
space or when it is desired to specifically monitor and
control the conditions at a particular location in a larger
conditioned space.
Both the need for and location of the remote sensor should
be determined by a heating/cooling professional. In most
installations, the onboard sensor in the DEH 3000R will be
sufficient to monitor and control the conditioned space.
5.2 Install and Wiring Instructions
1. Routing signal wires:
You will be required to supply and route 24 gauge, 4
conductor solid wire (2-line telephone wire) between the
DEH 3000R controller and the remote sensor location. The
wiring run should be no longer than 100 ft. Avoid routing
this interconnect wire parallel to high voltage wiring.
Maintain a distance of 2 ft. or more from high voltage lines.
2. Sensor connection:
The sensor can be mounted to a wall or ceiling surface.
Ideal sensor location is 5 ft. above the floor. Wires should
exit through a ½” diameter hole in the mounting surface at
the mounting location. Use the provided splice connectors to
connect the 4 wires from the remote sensor to the user-
supplied interconnect wire. Be sure to keep proper colors
attached to each other.
3. Sensor mounting:
You will need two screws to mount the sensor. Use the two
slotted holes to mount the base of the sensor to the wall and
then snap the cover into place.
4. Controller connection:
Use the provided splice connectors to connect the 4 wires
from the DEH 3000R to the user-supplied interconnect wire.

TAKE PRECAUTIONS AGAINST SAME), LOST PROFITS,
DELAY, OR LOSS OF USE OR DAMAGE TO ANY REAL OR
PERSONAL PROPERTY.
Some states do not allow limitations on how long an
implied warranty lasts, and some do not allow the
exclusion or limitation of incidental or consequential
damages, so one or both of these limitation may not
apply to you.
LEGAL RIGHTS: This warranty gives you specific legal
rights, and you may also have other rights which vary
from state to state.
