PURPOSE OF THE VENTILATION SYSTEM

Your ventilation system is designed to provide fresh air to your home while exhausting stale air from your home. By eliminating accumulated pollutants and humidity, it maintains an optimum air quality and an ideal relative humidity.

Fig. 2 - Typical Installation

NOTES:

1. Typical installation shown with a forced air system, which 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.

HEAT RECOVERY

Your ventilation system is equipped with a heat recovery core that is 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.

Fig. 5 - Integrated Control

Boot Sequence of Integrated Control

The unit boot sequence is similar to a personal computer boot sequence. Each time the unit is plugged after being unplugged, or after a power failure, the unit will perform a 30-second booting sequence before starting to operate. During the booting sequence, the integrated control LED will light GREEN (unit set in normal defrost) or AMBER (unit set in extended defrost) for 5 seconds, and then will shut off for 2 seconds. After that, the LED will light RED for the rest of the booting sequence. During this RED light phase, the unit is checking and resetting the motorized damper position. Once the motorized damper position completely set, the RED light turns off and the booting sequence is done.

NOTE: No command will be taken until the unit is fully booted.

Defrost Mode

When the outside temperature is below -5^ ( 23^ ), heat recovery 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 6–10 minutes (or 10 minutes if set on “Extended 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.

20-Minute Lighted Push-Button

Press once to activate the push-button. The unit will operate on high speed for 20 minutes and the indicator will light up. To stop activation before the end of the 20-minute cycle, push one more time.

One-Touch Control

Activate the push-button. The color of the indicator shows the unit operating mode.

High - This mode is recommended for the removal of excess pollutants and humidity. The ventilator will operate at its maximum speed continuously. The power indicator light will be lit red when this mode is selected.

Low - This mode is recommended for normal daily operation. The ventilator will operate at its minimum speed continuously. The power indicator light will be lit yellow when this mode is selected.

Intermittent - This mode is recommended when the inside air is too dry in the heating season or too humid in the cooling season. The ventilator will operate at its minimum speed for 20 minutes per hour and be off for 40 minutes per hour. The power indicator light will be lit green when this mode is selected.

Off - To turn the ventilator off, press "Push" until the power indicator light is turned off.

Dehumidistat Control

Adjusting DEHUMIDISTAT (standard control)

Setting during summer months:

During this period, unless being afflicted with breathing problems, using the Dehumidistat is unnecessary. Set the slide switch to "OFF". (Do not exchange in day time; exchange at night time, if cool outside, or if it is not raining.)

Setting during fall, winter and spring months:

(When severe condensation appears on windows.)

1. Determine the humidity level in your house (bring the knob (B) counterclockwise to its maximum position, then bring it back clockwise slowly until you hear a "click").

2. Set the knob to one line under this temperature level or "click".

IMPORTANT: Do not select a temperature below -20^ ( -4^ ). This could lead to excessive dryness in the air causing discomfort for the occupants.

It is possible (and normal) to experience condensation on your windows when drastic changes in temperature happen (for example: -5^ [23^] to -20^ [-4^] ). In that case, we suggest waiting a few days to allow the situation to stabilize.

Recommended Humidity Levels (Heating Operation)

In order to prevent condensation on interior windows, do not exceed humidity levels shown on table.

OUTSIDE TEMPERATURE	DOUBLE-PANE WINDOWS	TRIPLE-PANE WINDOWS
50^ / 10^	55%	65%
32^ / 0^	45%	55%
14^ / -10^	35%	45%
-4^ / -20^	30%	45%
-22^ / -30^	25%	35%

Adjusting DEHUMIDISTAT with Latent Control (ERV only)

• Low Exchange Mode — If the relative humidity inside the building is lower than selected, air exchange would occur with the outside at high speed. If the relative humidity level inside the building is higher than selected, air exchange would occur outside at low speed. This ensures continuous air exchange for constant air quality.
• Intermittent Mode — If the relative humidity inside the building is higher than selected, no air exchange would occur, and the system would turn off. If the relative humidity inside the building is lower than selected, air exchange would occur with outside at high speed. This mode is ideal for maintaining the proper humidity level when the continuous mode cannot.
