  • Page 9 Residential HRV/ERV Backdraft or motorized dampers may be built into the HRV/ERV to prevent entry of outdoor air during off cycles, but they should not be installed in the duct leading to the outside. Due to these reasons, it may be preferable to avoid a direct duct connection to the return of the AHU and use an indirect approach instead.

  • Page 11: Locating The Air Exchanger

    Residential HRV/ERV Locating the Air Exchanger The device must be located in a place where the temperature is always above freezing. Choose a location for the device where the ducts will be short with minimal use of elbows. This ensures that the system functions optimally. Ducting Materials WARNING: Always validate with the Building Code in effect before designing your ducting.

  • Page 14: Locating The Exhaust Air Grilles Or Registers

    Residential HRV/ERV Guidelines for locating intake and exhaust wall hoods Note: Local codes may allow less or require greater distances between exhaust and intake wall hoods. Locating the Exhaust Air Grilles or Registers (in systems with dedicated exhaust ducting) The exchanger has at least one exhaust air intake register. Exhaust air registers should be placed where the humidity level is high, such as bathrooms, laundry rooms, and kitchens.

    These grilles should not be adjusted after balancing the unit. Zone Register Terminals (ZRT ® Aldes patented* Exhaust Zone Register Terminals (ZRT®) are designed to introduce flexibility and on- demand control to central ventilation systems. Used in both large and small systems, the ZRT zonally regulates ventilation without the need for individual fans.

    Residential HRV/ERV ZRT VentZone® Systems VentZone® Systems by Aldes combine model ZRT demand-controlled zone register terminals and Heat Recovery Ventilators (HRV) or Energy Recovery Ventilators (ERV) to create the most advanced home ventilation solution. Zone Register Terminals (ZRT) replace individual fans or static grilles, which control the fan so that areas are only ventilated as desired.
  • Page 30 Residential HRV/ERV Getting Started Before installing your ventilator, the unit must be configured to operate in SLAVE mode (see page 20). Depending on selection, the ZRTs will be designed to operate on 120V power or 24V power provided by the ventilator itself. If you are not certain what you have, this can be easily determined by the color of the wires on the ZRTs.

    Residential HRV/ERV Adding Accessories to the VentZone® System Due to the operation of the VentZone® System, most Aldes controllers cannot be utilized. If desired, the VentZone® System can be used with the Aldes Humidity Controller (P/N 611224). Use of this controller requires one additional ZRT-1-6-24 to be controlled by said controller in order to prevent unwanted pressurization of the home.
  • Page 32 Residential HRV/ERV Door-Port Balancing – Measuring Airflow Finish sealing the ductwork system. Make sure all the HRV/ERV components are in place and functioning properly. Prepare the pressure gauge by mounting it according to manufacturer’s instructions and zeroing the gauge. Prepare the HRV/ERV and select the operating speed. For most installations, measuring at high speed permits a more accurate reading, and the system will normally remain in balance at lower speeds.
