ABOUT THIS MANUAL/PRODUCT
The purpose of this manual is to help you with the use of your unit. Section 2
(How to Operate the Unit Using Controls) shows you how you can operate the unit in no time. Section 3 deals with maintenance and explains how to maintain the unit to ensure maximum operation and performance. In the other sections, for example troubleshooting, you will learn how to solve minor problems (Section 4); plus other important information which we urge you to read.
In simplifying explanations, all drawings (figures) in this manual show the unit installed in the “normal” position. However, please note that your unit can be installed in either the “normal” or “reverse” (upside down) position. Several models are described in this publication. Some details of your unit may be slightly different than the ones shown, as the illustrations are typical ones.
We welcome any suggestions you may have concerning this manual and/or the unit, and we would appreciate hearing your comments on ways to better serve you. Please forward all correspondence to us at the address indicated on the product’s registration card included with this manual.
This manual uses the following symbols to emphasize particular information:

1.2 P URPOSE OF THE V ENTILATION S YSTEM
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.
VH0006
NOTES: 1. Shown with a forced air system. Can also operate on its own.
2. Installation may vary according to the model number and the position
(normal or reverse) in which the unit is installed.

1.3 R ECOVERY
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 exhausted 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) :
STALE AIR TO OUTSIDE 6°C FRESH AIR TO BUILDING 16°C
FRESH AIR FROM OUTSIDE 0°C
VF0026
STALE AIR FROM BUILDING 22°C
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 problems 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).
Example 1
(in winter):
Stale and humid air from building
22°C / 72°F
Example 2
(in summer with air conditioning):
Stale and dry air from building
26°C / 79°F
VF0030
Dry fresh air from outside
18°C / 64°F

1.4 F ILTRATION (only applicable to units operated with Ultima main control)
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 .
1.5 D
EFROST
M
ODE
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 for Solo models and 9 minutes for
Duo models (or 10 minutes for all models 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.

2.2 U SING THE V ENTA M AIN C ONTROL
Location: Located in the busiest area of the house.
Purpose: To adjust air supply and select desired indoor humidity level.
A DJUSTING THE AIR SUPPLY CONTROL a) Select speed “MIN.” or “MAX.” using switch A (as shown on diagram).
• When “MIN.” (minimum speed) is selected, if the knob B is set above the click, the unit will exchange in low speed with the outside and if it is set below the click, the unit will exchange on high speed with the outside until the desired humidity level has been reached.
B
• When “MAX.” (maximum speed) is selected, the unit will exchange on
VC0010 high speed with the outside either if he knob B is set below of above the click.
b) To turn the unit off , place selector A at the “OFF” position.
Optional controls, however, may still be active.
A
A DJUSTING THE HUMIDITY CONTROL
Setting during the summer months:
During this period, unless being afflicted by breathing problems, using the humidity control is unnecessary. Set switch A to OFF. (Do not exchange in day time; exchange at night time, if cool outside, or if it is not rainning.)
Setting during the fall, winter and spring months:
1) Determine the humidity level in your house (bring the knob B counterclockwise to 20%, then bring it back clockwise slowly until you hear a “click”).
2) Set knob B to 1% under this temperature level or “click”.
NOTES: 1. Do not select a humidity level below 30%. This could lead to excessive dryness in the air causing discomfort for the occupants.
2. When the humidity level is high, the unit automatically operates at maximum speed. If you change the setting of your “AIR SUPPLY” knob ( B ) at that time, it will remain at maximum speed until the humidity level is reduced, and then switch to the desired setting.
It is possible (and normal) to experience condensation on your windows when drastic changes in temperature happen (for example: -5°C (23°F) to
-20°C (-4°F) within few hours). In that case, we suggest waiting a few days to allow the situation to stabilize.

HUMIDITY CONTROL
Setting during the summer months:
Normally, excess humidity 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:
Ideally, maintain humidity level within the “ Comfort Zone ” (between 5°C and
-20°C), which is the dark area around knob B .
To reduce humidity level, turn knob B clockwise a notch below the click. The unit will then switch to high speed, lighting up the humidity light ( D indicator).When
this light goes "OFF" (after a few hours or a few days), repeat the same procedure if excess humidity persists.
NOTE: If the air is too dry, set your knob B back to the “ Comfort Zone ” and use
INTERMITTENT or turn off the unit.
When the humidity light ( D indicator) goes "ON", you can still change the mode of operation but your change will take place only when the light goes OFF.
