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 outdoor 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.

CAUTION
When leaving the house for a long period of time (more than two weeks), a responsible person should regularly check if the unit operates adequately. If the ductwork runs through an unconditioned space (e.g.: attic), the unit must operate continuously except when performing maintenance and/ or repair. Also, the ambient temperature of the house should never drop below 65°F. At least once a year, the unit mechanical and electronic parts should be inspected by qualified service personnel.

REPLACEMENT PARTS AND REPAIR
In order to ensure your ventilation unit remains in good working condition, you must use Broan-NuTone LLC genuine replacement parts only. Broan-NuTone LLC 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. Broan-NuTone LLC also recommends to contact a Broan-NuTone LLC certified service depot for all replacement parts and repairs.

DEFROSTING MODE

When the outdoor temperature is below 23°F, recovery of heat in HRV units creates frost in the core. For ERV units, when the outdoor temperature is below 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 outdoor temperature. During the defrost cycle, the dampers of the unit close but the unit speed can be set on high or low, according to your needs, using the VT9W main wall control. Refer to the Main and auxiliary wall controls user guide (included with your unit and also available at www.broan.com) for more details. After defrosting, the unit returns to the operating mode selected by the user.

BOOTING SEQUENCE

The unit and VT9W wall control booting sequence is similar to a personal computer booting sequence.
Each time the unit is plugged after being unplugged, or a power failure occurs, the unit will perform a 30-second booting sequence before starting to operate. During the booting sequence, the unit is checking and resetting the motorized damper position, while the VT9W wall control screen displays 5%, 10%, 15%, etc. (up to 100%). Once the motorized damper position completely set, the booting sequence is done. NOTE: No command will be taken until the unit is fully booted.

MAIN AND AUXILIARY CONTROLS

The only main control compatible with these units is the VT9W (purchase separately). Only one main control can be connected per unit.
Up to five VB60W push button auxiliary controls can be used.

NOTE: When used, the VB60W activation will override the VT9W operation, as well as the unit defrost cycle. The chronometer icon appears on VT9W screen as long as the VB60W is activated.

For more information about your unit controls, refer to the Main and auxiliary wall controls user guide (included with your unit and also available at www.broan.com).

MAINTENANCE

WARNING!
