Congratulations!

You have made an excellent choice! The operating principle of your Heat Recovery Ventilator or your Energy Recovery Ventilator will give you personal comfort you have never known before.

We have prepared this User Guide especially for you. Please read it carefully to ensure you obtain full benefit from your unit. Over the coming months, you will increasingly appreciate the feeling of living in a more comfortable house.

Please take note that this manual uses the following symbols to emphasize particular information:

WARNING

Identifies an instruction which, if not followed, might cause serious personal injuries including possibility of death.

CAUTION

Identifies an instruction which, if not followed, may severely damage the unit and/or its components.

NOTE: Indicates supplementary information needed to fully complete an instruction. We welcome any suggestions you may have concerning this guide 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 registration

card included with this guide.

CAUTION

Make sure at all times that the outside intake and exhaust hoods are free from any snow during the winter season. It is important to check your unit during a big snow storm, so it doesn’t draw in any snow. If this is the case, please operate the unit in the recirculation mode, or turn it OFF for a few hours. Do not use your unit during construction or renovation of your house or when sanding drywall. This type of dust may damage your system. Since the electronic control system of the unit is incorporated with a microprocessor, it may not operate correctly because of external noise or very short power failure. If this happens, unplug the unit and wait approximately 10 seconds. Then, plug the unit in again.

1. DEFROSTING MODE

When the outside temperature is below -5°C (23°F), recovery of heat in HRV units creates frost in the core. For ERV units, when the outside temperature is below -10°C (14°F), recovery of energy creates frost in the core. To maintain its proper operation, the unit is programmed to defrost the recovery core. The defrost frequency varies according to the outside temperature.

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. CONTROLS

2.1 BOOTING SEQUENCES

BOOTING SEQUENCE (HRV EKO 1.5 AND ERV EKO 1.5 ONLY)

The unit booting sequence is similar to a personal computer booting 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 AMBER for 10 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.

BOOTING SEQUENCE (CONSTRUCTO 1.5V AND NOVOFIT 1.0 ONLY)

The unit booting sequence is similar to a personal computer booting 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.

DEHUMIDISTAT OVERRIDE SELECTION

In the operating modes MIN, MAX, 20 min./h. and RECIRC (if available), the user can select a dehumidistat override so that if the relative humidity (RH) in the house exceeds the RH setting previously stored, the ventilation unit will exchange in high speed until the target indoor RH setting is reached.

An air exchanger is not a dehumidifier, but it can change the indoor relative humidity by bringing in drier or more humid air from outside during non heating season. The dehumidistat override function is useful to reduce indoor RH when the outdoor air is cool and dry during the heating season. Select a target RH between 30% and 55% according to your comfort. When outdoor relative humidity is high (e.g. in summer), turn off the override by pressing OK until the RH display disappears.

When the dehumidistat override is activated, the AUTO indicator will appear on LCD screen to show that the actual mode is being overridden. Also, the relative humidity appears (if it was not shown, see example beside). Once the target humidity level is reached, the unit goes back into its original operating mode and AUTO disappears from LCD screen.

NOTE: If the actual mode is MAX, only the relative humidity level appears on screen, AUTO label willl not appear.

To engage the humidity override, press OK. The actual indoor RH and the %HUM label appear on LCD screen.

NOTE: If the actual RH is less than 20%, then the humidity indicator will display “LO”, and if the actual RH is greater than 80%, then the humidity indicator will display “HI”.

To turn off the dehumidistat override, press OK again. The RH and %HUM display will disappear from LCD screen.

MAINTENANCE INDICATOR

The maintenance indicator is represented by an M in a rounded triangle, at the top of the house (see at right). If this indicator is flashing, perform the regular maintenance, and if it is not flashing, perform the annual maintenance (refer to Section 3).

RESETTING MAINTENANCE INDICATOR: Press simultaneously on both arrow buttons,

Setting during the 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 the 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”.

CAUTION

Do not select a temperature below -20°C (-4°F). 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°C [23°F] to -20°C [-4°F]). In that case, we suggest waiting a few days to allow the situation to stabilize.

REPLACEMENT PARTS AND REPAIR

In order to ensure your ventilation unit remains in good working condition, you must use Venmar Ventilation Inc. genuine replacement parts only. The Venmar Ventilation Inc. genuine replacement parts are specially designed for each unit and are manufactured to comply with all the applicable certification standards and maintain a high standard of safety. Any third party replacement part used may cause serious damage and drastically reduce the performance level of your unit, which will result in premature failing. Venmar Ventilation Inc. also recommends to contact a Venmar Ventilation Inc. certified service depot for all replacement parts and repairs.
