Frequently Asked Questions - Eos 100H PAX

How do I change the air filters?

Turn off the main switch. Open the front grille, pull the lever to unlock the front panel, and remove it. Pull the locking plate aside, remove the old OA filter, and replace it. For the RA filter, pull the extraction cartridge down, open it, and replace the filter. Close and reassemble.

How do I reset the filter maintenance indicator?

After replacing filters, press the filter button (marked FILTER) on the control panel or remote. The orange indicator light will turn off.

What should I do if the unit makes unusual noises?

Check if the unit is installed on a sturdy, level ceiling/wall. Some noises during start/stop are normal. If persistent, turn off power and contact a qualified installer.

How do I use the remote control?

Ensure batteries are not exhausted. Point the remote at the unit. Press button 4 to start/standby. Use buttons for airflow (3 steps), humidity (9 steps), and mode selection.

What do the different modes (Normal, Summer, Eco, Comfort) mean?

Normal: continuous heat exchange down to -15°C. Summer: supply air stops if outdoor air is >4°C colder than exhaust to increase comfort. Eco: heat exchange with limited preheating to avoid icing. Comfort: heat exchange with preheating to keep supply air above +18°C.

How do I adjust the humidity sensitivity?

Press the humidity button (labeled with a droplet icon) repeatedly. There are 9 steps between 40% and 88% RH. Three LEDs indicate the level (each step changes sensitivity by 6%). The unit enters forced exhaust mode when humidity exceeds the set level.

How do I perform an auto-balancing of the airflow?

Ensure the unit is installed and powered on. Press and hold the 'mode' button or a combination (see manual) for 3 seconds. The unit will run at high speed for 1 hour then adjust dampers. The process takes about 75 minutes. Do not interrupt power or press any buttons during balancing.

What should I do if the LED lights do not come on?

Check if the main power switch is on and the unit is not in standby. Verify home fuses. If still off, contact a qualified electrician.

How do I clean the front panel?

Wipe the front panel and frame with a damp cloth. Do not use solvents, gasoline, or harsh chemicals.

What are the warranty conditions?

The Pax Eos has a 5-year warranty for manufacturing defects, provided it is installed by a qualified electrician, assembled per instructions, cleaned regularly, used indoors, and not exposed to harsh environments.

Feature:

- House heated air is drawn into the Eos. But before it is sent out, it is used to heat the incoming fresh air, so that it largely is heated as soon as it enters the house.

- As the temperature and humidity can be recovered with Eos in-built heat exchanger, it is also possible to save air conditioning costs.

- Eos is designed to be installed indoors, temperature range from 5 to 35°C.

- Recommended ambient temperature in operation is approximal 20° C.

- Eos is automatically stopped when the outside temperature is below -30°C.

NOTE:

- Eos is factory set to start at a moisture level of 88%.

Possibility to change the starting point is by adjusting the levels of key in 9 levels between 40-88%.

• Moisture level is indicated by three LEDs, each LED indicates where the third level (3, 6 and 9 th level, each step change sensitivity by 6%)
• When the set humidity level is reached Eos goes to work only in forced extraction mode. When the humidity later falls below the set level, the unit will continue at forced in 20 minutes for the moisture level to stabilize.

Then returns to its normal Eos heat exchange operation.

(Important to think about the starting point for forced exhaust air is adjusted to a lower value than 88%. During summer, when the relative humidity is high, it may be necessary to adjust the starting point to a higher level to prevent Eos from being forced into exhaust air mode only.)

[6] Then use the template holes on the outside of the wall to mark the second hole position. Use a water pass so the holes get in horizontal. This will make you a safer positioning of markers to use hole saw. Next make up the larger holes D = 110 mm (adapted for channels D=100mm) by sawing through the wall from both inside and outside.

Plastic channels described below is an accessory for Pax Eos.

[7] Cut the plastic channels according to the wall thickness of the housing, place the channels in the holes for outdoor air and exhaust air. Seal the space between wall and channel through joint sealing.

[10] Put frame (C) and connectors (D) in place, align frame horizontally and fasten with two screws. (Take advantage of holes in the frame that will not be used later.)
[11] Screw the louvers (E) so they will always be facing away from each other and that they also protect against rain. When the entire external wall grille is bolted, seal around the frame edges so no rainwater can penetrate between the frame and outer wall.

Press the assembly against the ceiling mounting plate while as the unit moved against SA / EA air ducts.

The mounting plate has a hook arrangement (A) matches in a corresponding part of the unit.

The hook is an aid that unit temporary can hang out in while the screws pulled, see Figure [16].
