5. Press the
“CLOCK”
button again and the day display will
flash. Use the
“RH”
buttons to change the value.
6. Don’t touch any buttons for several seconds until the display
stops flashing, this will save your settings. If you need to
change anything go back to step #1.
3.6 Adjusting the relative humidity “SETPOINT”
The DEH 3000R 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%.
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).
3.7 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.
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.
