3.6 Adjusting the relative humidity “SETPOINT”

The DEH 3000 senses the ambient relative humidity (%RH) of the space in which it is located, it comes factory preset to hold

50% relative humidity.

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%.

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 3000 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.

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).

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.

Installation, Operation & Service Manual

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 3000 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.

The DEH 3000 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:

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).

2. Using the up/down

“RH” buttons, highlight “PROGRAM” and select it by pressing the

“PROGRAM ENTER” button.

The following menu appears:

4.0 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 3000 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.
