between the top windowpane and the lower window frame with the stiff insulation facing indoors. For some windows
with a narrow opening the insulation may be need to be smaller. Cut the insulation along the width on the softer
insulation side using scissors and install.

Operating Instructions
EcoBreeze2 controls are designed to optimize the efficiency of cooling with outside air
1. On/off button
2. Manual fan button
3. Humidity control button
4. + Temperature Increase button
5. – Temperature decrease button
6. Set up button
Power
Plug the unit into a 120 volt outlet. Press the on/off button to turn the unit on and off.
Set desired indoor temperature
Use the +/- to raise or lower the desired indoor temperature set point. The display will show the set point temperature
when it is being changed and then show the room temperature. A lower set point will increase the use of outside air
and can precool the home delaying the need for air conditioning.
Set humidity on/off
EcoBreeze 2.1 has a humidity control feature that increases energy efficiency and comfort when the unit is being used
with air conditioning. When the control is on, the unit continuously monitors indoor and outdoor humidity and will not
bring in outside air that is more humid than the indoor air. When the control is on the display light on the control panel
will illuminate. When air conditioning is not used the control can be turned off and the display light will turn off.
Please note EcoBreeze 2.1 measures dew point not relative humidity. A light indicates outside air is too humid to use.
Select the fan mode
This is for manual operation. Press the fan button to toggle through the fan modes. Speeds 1- low to speed 5- high
Auto mode
The room temperature will display in this mode. In the auto mode the controls will determine when cooling is needed
and available based on the set point. The fan will also automatically adjust the fan speed for maximum energy
efficiency. It will gradually increase the speed as the outdoor temperature drops and then decrease it as it nears the set
point.
Manual speed mode
The fan will run continuously on this setting. Press the fan button to toggle through 5 speeds, from low to turbo speed.
Then one more press will go back to auto mode.
Change the filter
The filter should be changed regularly to maximize cleaning effectiveness. The filter reminder can be adjusted based on
the conditions in the area. If the filter is clogged go to the setup and reduce the hours between filter changes. If the
filter is clean increase the hours between filter changes. The filter drawer is at the bottom of the unit. It may be opened
with the handle on the bottom or the two finger tabs on the side of the unit. Slide the drawer completely out of the
unit. Slide the cover back to access the filter. Remove the existing filter and replace with a new filter. The filter
dimensions are a nominal 12” x 12” x 1” and may be purchased from Nature’s Cooling Solutions. The filter has a
direction indicator for the airflow direction. The filter should be installed so the airflow goes toward the top of the filter
drawer. Replace the filter drawer for operation.

Trouble shooting
EcoBreeze 2.1 not running
In auto mode EcoBreeze 2.1 will stay on or off for a
minimum of 3 minutes.
Confirm set point is less than indoor temperature.
If outdoor temp is illuminated outdoor temperature is
greater than indoor temperature and the fan will not
run.
If outdoor humidity is illuminated outdoor dew point is
greater than indoor dew point so the fan will not bring
in humid air. This only works when the humidity lock is
on.
Check temperature and humidity readings.
Indoor temperature is displayed when no changes are
being made. The rest of values can be displayed by
pressing the settings button.
First press – displays the hours remaining until the filter
needs to be changed. Press +/- to reset to the
maximum hours
Second press – Displays the outdoor temperature
Third press – Displays the indoor humidity dew point
temperature
Fourth press – Displays the outdoor humidity dew point
temperature
Air flow decreases
If air flow decreases check the filter. If it is dirty change filter and adjust filter reminder lower.
