HD330/AW-HD330 Dual Output Programmable Humidity Controller
Version 1.3 (Jan., 2022)
1. Overview
The HD330 is a dual-output humidity controller with 8 programmable steps. It
contains one humidity sensor and two independent outputs. One output is for
humidifier and the other is for dehumidifier. The humidity control can be
programmed to vary with different time step setting. It can program up to 8
humidity-time steps and cover 33 days. By using both the humidifying and
dehumidifying outputs, the humidity ratio can be controlled at a specific value
regardless of whether it is in dry or wet environments.
This controller is a plug-n-play controller, meaning that there is no extra wiring
is needed for the humidifier or dehumidifier. Both humidifying and
dehumidifying control modes contain a simple on/off operation; they are similar
to a mechanical humidistat but operate with higher precision due to adjustable
hysteresis band, a precise sensor, and digital read out.
Different operation humidity ranges of the two outputs can be set separately.
Once the dehumidifying range is set, the controller program will automatically
limit the humidifying range to prevent both outputs from being turned on at the
same time.
This humidifier controller is equipped with one of the most robust humidity
sensors on the market. It is designed for high relative humidity (>85% RH) and
condensing environments, where slight drops in temperature may cause failure
or damage to other humidity sensors, a feature many other sensors don’t have.
Wireless network connection capability is available in AW-HD330. Users can
access the humidity data and parameter settings of the controller from their
smart phones or tablets. The AuberWIFI App is available on both iOS and
Android platform. For details, please check the supplementary manual.

Note 1. AH, Deviation high alarm; AL, Deviation low alarm:
Assuming measured humidity is PV and set humidity is H. When PV - H is
above AH, the built-in buzzer will turn on (deviation high alarm); when H –PV
is above AL, the built-in buzzer will turn on (deviation low alarm). Users can
mute the alarm by momentarily pressing the Mute key. The alarm will remain
inactive until the process value moves out of the alarm zone. Both alarms are
deviation alarms, i.e., if AH = 20%, AL = 30%; and the Set Humidity (H) is 50%
RH, the alarm will be activated if the humidity is above 70% or below 20%. The
alarm function is suppressed at powering up or when the program jumps from
one step to another step. It will be activated automatically once the measured
humidity enters the none-alarm zone (between H - AL and H + AH).
Note 2. Hy, Humidity Control Hysteresis Band, or Humidity Control Dead Band:
This parameter sets up a hysteresis band (dead band) within which either the
humidifier or dehumidifier will not work (between H - Hy and H + Hy). The
minimum value for Hy is 0.5. The Hy value should not be too small if the
system has sluggish response. Otherwise, it may result in the humidifier and
the dehumidifier working against each other, wasting energy and causing
oscillation.

AUBER INSTRUMENTS WWW.AUBERINS.COM
2022.01 P3/5
Note 3. Hyd, Dehumidifier Hysteresis Band:
This is the differential band between to turn on and turn off the dehumidifier. It
is set to the higher side of the dehumidifier set point (H + Hy). The dehumidifier
will turn on when humidity is above (H + HY + Hyd) and turn off when humidity
is below (H + Hy). For compressor-based dehumidifier, the Hyd value should
not be set too small to prevent frequent cycling.
Note 4. HyH, Humidifier Hysteresis Band:
This is the differential band between turn on and turn off the humidifier. It is set
to the lower side of the humidifier set point (H - Hy). The humidifier will turn on
when humidity is below (H - HY - HyH) and will turn off when humidity is above
(H - Hy).
For example, if Set Humidity H = 50%, Hy = 5%, Hyd = 3%, HyH = 2%, then
the humidifier will turn on when the process humidity is lower than 43% (H - Hy
- HyH) and will turn off when process humidity is above 45% (H - Hy). The
dehumidifier will turn on when process humidity is above 58% (H + Hy + Hyd)
and turn off when process humidity drops below 55% (H + Hy).
Note 5. OFS, Humidity Offset:
OFS (Humidity Offset): OFS is used to compensate for the error produced by
the sensor or input signal itself. For example, the unit displays 37% when the
actual humidity is 32%. Setting parameter OFS = - 5 will make the controller
display 32%. The displayed process humidity = actual measured humidity +
OFS.
Note 6. AS, Anti-short Cycle Delay:
The Anti-short is the delay time to turn on the dehumidifier. If the dehumidifier
is compressor based, the compressor should not be turned on immediately
when it is at high pressure (just after turned off). Otherwise, it may shorten the
life of compressor. The Anti-Short cycle delay function can be used to prevent
the rapid cycling of the compressor. It establishes the minimum time that the
compressor remains off (after reaching cutout) before turns on again. The
delay overrides any controller demand and does not allow the compressor to
turn on until the set time-delay value has elapsed. It gives time to release the
refrigerant pressure through evaporator. It typically set to 4- 6 (minutes). The
unit is in minutes. This setting is only valid for dehumidifying control.
Note 7. PrG, Program Mode:
When PrG is set to “ON”, users can program up to 8 steps (Section 5). When
PrG is set to “OFF”, this controller is in single step mode (multi-step function is
disabled). In single step mode, users can only set “H-1” set point and the
controller will regulate the humidity at “H-1” set point forever. No step timer nor
other step set points can be set in single step mode. Please be aware that if
your controller is in single step mode, the green "RUN" indicator will be off at all
time. The start, pause, and STEP keys are disabled. You can check the
dehumidifier indicator (red on the left) and humidifier indicator (green on the
right) for the socket output status. When the light is on, the corresponding
socket will be activated.
Tip: After you change PrG parameter, please reboot your controller so
new setting will be activated (remove the power input cord of this
controller then plug it back).
Note 8. A-M, Power Outage/Startup Mode:
This parameter determines what the controller should do in an event of power
interrupt or outage. It also decides how the controller starts the program while
powered up. A-M can be set to three modes: C, S and M.
Mode C. After being powered on, the controller will continue the program from
the where it was powered off. For example, if step 3 is set for 40% and 5
hours, the power was interrupted at 2.1 hours. When the controller powers up,
the controller will continue to control at 40% for 2.9 hr.
Mode S. The controller will run the program from step 1 every time the
controller is powered up. This is suitable for situations where the power never
fails or when the program mode “PrG” is set to “off”.
Mode M. The program will be held at the step at which the controller was
powered off. The controller will hold the humidity at the set value. The
controller lower display will flash "hold" and process humidity alternatively. This
mode is suitable for situations where the operator’s attention is needed after
power interruption occurs.
Note 9. SFA, Sensor Failure Operation:
The SFA defines how the output would be if the sensor fails. It can be set to 0-
0, 0-1 or 1-0. Please refer to Table 3 for details. For example, in some
applications, you may want the dehumidifier to be ON and humidifier to be OFF
when sensor fails. Hence you need to set SFA to “1-0”.
Table 3. Output of the controller when sensor fails.
SFA
Controller output when sensor fails
0-0
dehumidifier off, humidifier off
1-0
dehumidifier on, humidifier off
0-1
dehumidifier off, humidifier on
Note 10. TIM, Time unit setting:
The Time defines the timer unit setting for its timer function. It can be set to
hour (H) or minute (M). By default, Time is set to H.
Note 11. PSD, App access code (for WIFI model only):
To prevent the operator from changing the settings by accident over the
AuberWIFI App, this access code is required. The default value is 666.

Figure 4. Flow chart of setting up control program.
A total of 8 steps can be programmed in this controller. Each step contains the
humidity set point (H-X) and time duration (t-X), where “X” is the step number
(e.g. step 4 humidity is represented by H-4, and step 4 time is represented by t-
4). Once time is up, this controller will jump to next step. The time unit can be
set to hour or minute.
To program the humidity profile, briefly press the SET key momentarily. The
top display will show “H-1”and the bottom display will show the humidity set
value for “H-1”. Use the ▲or ▼keys to adjust the bottom display to the
desired value. Then press the SET key again to save the changes and go to
next parameter. Then the top display will show “t-1” and the bottom display will
show the preset time for step 1. Use the ▲or ▼keys to adjust the bottom
display to the desired value. Then press SET key again to save the changes
and proceed to next parameter. Repeat operations above until you finish
programming all necessary steps. You can set the time for rest of the steps to
zero so that the controller will skip these steps.
Note: The set value will not be saved unless SET is pressed. The controller will
return to the normal operating mode automatically if it is left alone for 10
seconds.
7. Check the Status
Step Running Time: This indicates how much time has passed since the
beginning of the current step. You can check the Step Running Time while the
controller is in the Program Run Mode by:
1) Short press the STEP key so the display window will show the current step
number “P - X”.
2) Wait about 1 second for the step running time to appear in the display
window.
3) Press STEP key again to check the Total Power-on Time (see below) or not
touching any key for 10 seconds so the display window will show the humidity
reading again.
Total Power-on Time: Total Power-on Time shows how much time has
passed since the controller is powered on. You can check the Total Power-on
Time in Program Run, Hold, or Stop Mode:
1) Short press the STEP key twice, you can see “tol” shown in the display
window shortly, and then the Total Power-on Time will be shown.
2) Press STEP again to return to humidity reading.
Once the whole program is finished, the display will show “End” and buzzer will
be ON. Press the start key once to restart the program.
8. Program Jump
This controller allows users to skip parts of the program by jumping to a
specific program step. For example, the controller has run 3 minutes in its 2nd
step. If the user wants to skip the rest of the 2nd step and the entire 4th step,
then the user can jump to step 4.
To jump to a specified step:
1) Put the controller in either Program Hold or Stop Mode.
2) Press STEP key so the controller will flash “J-X”, where “J” indicates this
operation is for jumping to a step (“X” is the step number). Use the UP or
DOWN arrow keys to change step number, then press START key to confirm
and jump. The display window will show JMP (“JUMP”) briefly to confirm that
jump is accomplished. Then controller will execute that step, the RUN indicator
will be lit (multi-step mode), and the display window should show humidity
reading as normal.
9. Alarm Buzzer
The controller has a built-in buzzer. Under the following situations, the alarm
buzzer will be triggered:
1) When the humidity alarm is triggered, the buzzer will keep on beeping until
the MUTE key is pressed.
2) When a program step (other than the 8th step) is finished, the buzzer will
beep twice.
3) When the entire program is finished (the 8th step), the buzzer will keep on
beeping until the MUTE key is pressed.
When the alarm buzzer is beeping, you can press MUTE key to mute the
alarm.
