YOUR UNIT AND ITS PURPOSE

Your ventilation system is designed to provide fresh air, warmed outdoor air to your home

while exhausting stale, humid air from your home. By eliminating accumulated pollutants and

humidity, it maintains an optimum air quality and an ideal relative humidity.

1.2 PURPOSE OF THE VENTILATION SYSTEM

* Shown with a forced air system. Can also operate on its own.

** Installation may vary according to the model number and the position (normal or reverse) in

which the unit is installed.

SOLO

1. Basic filters

2. Blower

3. Condensation tray (on Solo unit only)

4. Heat recovery core or thermal wheel

5. Optional filter

DUO

*Units in normal position. Can also be installed upside down.

B) Units equipped with a thermal wheel (Duo units) can reduce ventilation costs in winter

as well as in summer by maintaining indoor humidity level for maximum comfort.

1. During the heating season,

the unit draws the humidity and heat from the stale air and

transfers them, in part, to the cold air entering the house, thus avoiding dryness prob-

lems and providing maximum comfort (example 1).

2. During the cooling season,

the unit reverses the process, preventing the humidity from

the outside air from entering into the house (example 2).

1.3 RECOVERY

A) Units with a heat recovery core (Solo units) are designed specifically to control excess

humidity and reduce ventilation costs by recovering the heat energy from the exhaust air,

and using that same heat energy to warm the fresh air being supplied. This heat recovery

process is accomplished in such a way that the stale air is never mixed with the fresh air.

Example (in winter):

OUTSIDE

INSIDE

STALE AIR TO OUTSIDE 6°C/43°F

FRESH AIR FROM OUTSIDE 0°C/32°F

FRESH AIR TO BUILDING 16°C/61°F

STALE AIR FROM BUILDING 22°C/72°F

When the outside temperature is below -5°C (23°F), recovery (of heat or energy) creates

frost in the module. To maintain its proper operation, the unit is programmed to defrost the

recovery module. The defrost frequency varies according to the outside temperature.

Defrost lasts 6 minutes (or 10 minutes if set on “Extented Defrost”). During the defrost cycle,

the unit shifts to maximum speed and the dampers close.

After defrosting, the unit returns to the operating mode selected by the user.

A) Basic filtration:

While in filtration mode, the unit ceases to exchange air with the exterior. Continuous

circulation and a mechanical filter ensure the purification of the ambient air inside the

house. The mechanical filter traps dust particles visible to the eye.

B) Optional filters (add-on to the basic filtration):

• Pleated: A second stage filter to trap dust particles.

• Electronic: Acts as the pleated model with increased efficiency.

• Activated carbon: Traps dust particles and odors.

1.4 FILTRATION (only applicable to units operated with Ultima main control)

Before 1980, houses were not adequately insulated and energy costs increased. To lower

these costs, builders looked for more energy efficient building techniques such as airtight

windows, vapor barriers, better insulation, better caulking, etc. All of these improvements

resulted in energy cost savings but also decreased natural ventilation. By keeping the heat

inside, we also trap the excess humidity and pollutants.

2.1 MAIN SOURCES OF POLLUTION INSIDE THE HOUSE

2.0 WHY VENTILATE

• Cigarette smoke

• Cooking and grease smoke emissions

• Pet dander and debris

• Smoke from fireplaces and wood-burning stoves

• Spores and pollen from indoor plants

• Dust

• Occupants skin danders

• Viruses, bacteria and mold

• Fumes from various chemical and cleaning products

• Mold and spores from excess humidity in basements and bathrooms

• Mites and their debris

• Radon gas seeping in through walls and foundations

2.2 MAIN SOURCES OF HUMIDITY INSIDE THE HOUSE

Volume of humidity in the air produced by various household tasks

2.3 THEN, WHY VENTILATE

As you can see, every cubic foot of air contains millions of tiny particles. These particles, as

mentioned, are so small that you would need a powerful microscope to see them. In small

quantities, these particles can bother you; in large quantities (large concentrations), they can

make you sick.

1. TO IMPROVE THE AIR QUALITY INSIDE

• Controlling pollutants and allergenic particles

• Reducing the damaging effects of allergies and asthma

• Controlling odors

• Increasing the oxygen level

2. TO CONTROL EXCESS HUMIDITY

• Reducing condensation on windows

• Protecting the house structure

• Preventing formation of mold

Location: Located in the busiest area of the house.

Purpose: To adjust air supply and select desired indoor humidity level.

DJUSTING THE AIR SUPPLY CONTROL

a) Select speed “MIN.” or “MAX.” using

switch A (as shown on diagram).

• Select “MIN.” (minimum speed)

for normal daily operation (24

hours a day all year round).

• Select “MAX.” (maximum speed)

for excess pollutants and humidi-

ty (parties, odors, smoke, etc.)

b) To turn the unit off, place selector at the “OFF” position. Optional controls,

however, may still be active.

DJUSTING THE HUMIDITY CONTROL

Setting during the summer months:

Normally, condensation is not a problem during this period, which therefore eliminates the

need for the humidity control. Set knob B at the “SUMMER” position during this period.

Setting during the fall, winter and spring months:

Method 1 (fast and simple for new users):

a) Determine approximately the outside daytime temperature.

b) Set knob B to this temperature.

Continue using this method for about a month before trying method 2 suggested below.

Method 2 (more precise adjustment):

Use Method 2 (steps “a” to “f” next page) if there is condensation on your windows

after using Method 1 for at least a month. As ventilation needs vary from one house to

another (depending on cooking habits, frequency of showers, washing, window cons-

truction, etc.), an adjustment based on outside temperature may not adequately solve

the condensation problem in your house.

3.2 USING THE VENTA MAIN CONTROL

a) Select “MIN.”.

b) Turn knob B clockwise until you hear a click.

c) Turn knob B a notch below the click.

d) 12 or 24 hours later, check if there is still condensation on the windows.

e) If there is, repeat steps b, c, d above (until desired results are obtained).

f) Compare the 2 values: that obtained with Method 1 and that obtained with Method

2. Use the variance for future reference. For example, if there is a 3 degree vari-

ance, you can conclude that, for your house, an adjustment of 3 degrees below the

outside temperature is required for optimum condensation control.

WARNING: Do not select a temperature below -20°C. This could lead to excessive dry-

ness in the air causing discomfort for the occupants.

It is possible (and normal) to experience condensation on your windows when dras-

tic changes in temperature happen (for example: from -5°C to -20°C). In that case,

we suggest waiting a fews days to allow the situation to stabilize.

3.2 USING THE VENTA MAIN CONTROL (cont’d)

3.3 USING THE SUPRA MAIN CONTROL

Location: Located in the busiest area of the house.

“MAX.” or “INTERMITTENT” light indica-

tor appears.

• Select “MIN.” (minimum speed)

for normal daily operation (24

hours a day all year round).

• Select “MAX.” (maximum speed)

for excess pollutants and humidi-

ty (parties, odors, smoke, etc.)

• Select “INTERMITTENT” when

you are away from the house for

a few days or when you deem the

inside air too dry.

b) To turn the unit off , press “PUSH” (A) until the “MIN.”, “MAX.” and “INTERMITENT”

light indicators are all turned off. N.B.: Optional controls will still be active. (Indicator

“C” will be the only one to light up if an optional control is active).

ADJUSTING HUMIDITY CONTROL

Setting during the summer months:

Normally, condensation is not a problem during this period, which therefore eliminates the

need of the humidity control. Set knob B at the “SUMMER” position during this period.

Setting during the fall, winter and spring months:

Method 1 (fast and simple for new users):

a) Determine approximately the outside daytime temperature.

b) Set knob B to this temperature.

Continue using this method for about a month before trying method 2 suggested below.

Method 2 (more precise adjustment):

Use Method 2 (steps “a” to “f” below) if there is condensation on your windows after

using Method 1 for at least a month. As ventilation needs vary from one house to ano-

ther (depending on cooking habits, frequency of showers, washing, window construction,

etc.), an adjustment based on outside temperature may not adequately solve the con-

densation problem in your house.

a) Select “MIN.”.

b) Turn knob B clockwise until you hear a click.

c) Turn knob B a notch below the click.

d) Wait until the “MAXIMUM SPEED” light indicator (D) turns off. Then, check if there

is still condensation on the windows. (Can take a few hours or a few days.)

e) If there is, repeat steps b, c, d above (until desired results are obtained).

f) Compare the 2 values: that obtained with Method 1 and that obtained with Method

2. Use the variance for future reference. For example, if there is a 3 degree vari-

ance, you can conclude that, for your house, an adjustment of 3 degrees below the

outside temperature is required for optimum condensation control.

WARNING: Do not select a temperature below -20°C. This could lead to excessive dry-
