  • 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. Recirculation Using Fifth Ports (Optional) Ducted Run the duct to an area with clean indoor air, such as a hall or living room.

  • Page 12: Vent Hood Locations

    Residential HRV/ERV Vent Hood Locations (Manufacturer’s recommendation only. Also consult Local Building Code Requirement.) Wall hoods (sold separately) should be located where accumulated debris can easily be removed. Note: Please refer to Installation Instructions packaged with wall hoods. Fresh Air (Intake) Wall hoods: •...

  • Page 13: Locating The Exhaust Air Grilles Or Registers

    Residential HRV/ERV 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. However, do not install in areas of extreme humidity such as steam showers, jacuzzi rooms, indoor pools and solariums.

  • Page 14: Zone Register Terminals (Zrt ® )

    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.

  • Page 15: Installation

    ASHRAE 62.2 standards recommend maintaining a relative humidity rate between 30% and 60%. The average person is comfortable between 30-50% relative humidity (RH). Aldes offers several wall controls with a dehumidistat function. Please refer to the wall control user guide for detailed information.

  • Page 16: Mounting The Unit

    To suspend the device, affix the four mounting brackets in the upper corners of the unit. Using the chains and the springs, suspend the air exchanger from the joists. Suspended by chains Wall-Mount Bracket (P/N 608575) Note: Models H/E190 and H/E240 cannot be installed using the wall-mount bracket.

  • Page 17: Drain Connections (Hrv Models)

    Residential HRV/ERV Drain Connections (HRV Models only ERV Models do not require plumbing.) Regardless of mounting method, the device should be installed level to ensure that condensation (produced during a defrost cycle) drains from the unit. The water should flow into a nearby drain or bucket.

  • Page 18: Interlocking The Hrv/Erv To An Air-Handler/Furnace Blower

    Residential HRV/ERV Interlocking the HRV/ERV to an Air-Handler/Furnace Blower Installations sharing duct with air-handling units or furnaces operate most effectively when those units are powered on to properly distribute the fresh air provided by the ventilator throughout the home. The HRV/ERV has the ability to interlock with external equipment, such as an air-handler or furnace blower, to activate or deactivate that equipment as necessary.

  • Page 19: Enabling Slave Mode

    Note: While in slave mode, the recirculation function is replaced with the standby, or OFF, condition. Aldes controllers which have this function will continue to work in all other modes, but the recirculation mode is replaced with the standby mode. If recirculation is required, but the HRV/ERV must be OFF by default, then install the unit in master mode and use the digital multifunction control 611242-FC to put the unit into standby mode.
  • Page 20 Residential HRV/ERV Using a Phillips head screwdriver, remove the three screws that secure the metal control board cover. Removing the screws With the cover removed, locate the jumper pins on the control board. These are positioned just behind the motor speed dials on the front of the unit. Locating the jumper pins...

  • Page 21: Using Slave Mode

    Residential HRV/ERV One of the jumpers comes from the factory offset. Moving the offset jumper to align with the other jumpers is what changes the unit from Master to Slave mode. Using your fingertips, gently pull the offset jumper away from the pins and reinstall so that it connects both pins on that row.

  • Page 23: Field Wiring

    The Digital Multifunction Control (P/N 611242-FC) can be used with any type of Aldes Residential HRV/ERV. The controller should be installed in the place where excess humidity is most likely to be detected, for example near a bathroom, kitchen or in the basement.

    Residential HRV/ERV Connect the 3-conductor wire to the device’s terminal according to its respective colors. See page 24 Section “Electrical Interface”. These wires carry a 24V current. Screw the backside of the control panel to the wall. Use the mounting screws to secure the top section into place.

  • Page 28: Zrt Ventzone® Systems

    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 29 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.

  • Page 30: Measuring & Balancing Airflow

    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.

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.
  • Page 32 Residential HRV/ERV Record the pressure measurement. Refer to the reference chart on the unit that shows the pressure readings versus the corresponding supply airflows. Record this airflow. Connect the tubing to the corresponding indoor air and exhaust air door ports using the diagram above.
