Residential HRV/ERV I. INTRODUCTION Thank you for purchasing a ventilation product from ALDES. To get the most out of your device, we recommend reading the user manual. II. GENERAL HRV/ERV TERMINOLOGY AND FEATURES Definitions Heat Recovery Ventilator: A ventilation device consisting of two fans and a heat recovery module to provide exhaust of stale indoor air, plus a balanced supply of fresh air, without mixing the two airstreams. -
Page 4: Ventilation With An Hrv/Erv
The way your home was built • Your preferences regarding the level of ventilation ALDES HRV/ERVs create a fresh air supply by recovering part of the energy from the exhaust air. A properly installed, well used, and well-maintained HRV/ERV: •... - Page 5 Residential HRV/ERV CAUTION Before installation, careful consideration must be given to how this system will operate if connected to any other piece of mechanical equipment like a forced-air central heating unit or a fan with a higher static pressure, for example.
-
Page 6: Ducting Configurations
Residential HRV/ERV ATTENTION This product is intended for residential use in accordance with the requirements of the International Residential Building and Mechanical Codes, NFPA 90B for the United States and the National Building Code of Canada. It is recommended to turn the unit off during renovations to avoid clogging the filters and loading the fans with dust. - Page 7 This system is not connected to an air handling unit or furnace. This system is normally balanced on high speed. If ALDES patented ZRT® are integrated into the ventilation system, Refer to the ZRT brochure for more airflow balancing should be performed at normal speed.
- Page 8 Residential HRV/ERV During the hot, humid season, continuous operation of the AHU can cause evaporation in the cooling tower, resulting in a loss of humidity control. If the AHU is not in phase with the HRV/ERV, this can lead to condensation in the supply system and ducts. Running the AHU continuously can cause draft effects in winter.
-
Page 9: Locating The Air Exchanger
This helps optimize the ventilation system. The Aldes unit must be installed in such a way that it is easily accessible for maintenance, inspection, repair or other work on the unit. -
Page 10: Avoiding Condensation In Your Unit
Residential HRV/ERV To ensure an optimal performance of the air exchanger, position the ducts so that they are as straight as possible. Ducts should be short and have no bends to maximize airflow. Forty-five-degree elbows are preferable to 90-degree elbows. Use “Y” rather than “T” joints wherever possible. -
Page 11: Vent Hood Locations
Residential HRV/ERV Vent Hood Locations (Manufacturer’s recommendation. Also consult your local building code). Wall-mounted hoods (sold separately) must be installed where they are easily accessible for cleaning. Note: Please refer to wall hood installation instructions. Fresh Air (Intake) Wall hoods: •... -
Page 12: Locating The Exhaust Air Grilles Or Registers
Residential HRV/ERV Locating the Exhaust Air Grilles or Registers The air exchanger system must have at least one exhaust air register. Exhaust air registers should be installed in areas where humidity is highest, such as bathrooms, kitchens or laundry rooms, but not in steam showers, jacuzzi, indoor pools or solariums. Do not connect the cooker hood to the HRV/ERV. -
Page 13: Humidity Control
ASHRAE 62.2 standards recommend maintaining a relative humidity rate between 30% and 60%. The average person is comfortable between 30 and 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 14: Drain Connections
Residential HRV/ERV Drain Connections (HRV Models only) Regardless of mounting method, the device should be installed level to ensure that conden- sation (produced during a defrost cycle) drains from the unit. The water should flow into a nearby drain or bucket. CAUTION: HRV must be installed level to ensure proper condensate drainage. -
Page 15: Mounting The Unit
Residential HRV/ERV Mounting the Unit The air exchanger is designed to be suspended or installed on a wall bracket (sold separately, P/N 699921). To suspend the unit, screw the hooks at the top corners of the unit into the holes provided. Using chains and springs, hook the air exchanger chains to the ceiling joints. To facilitate installation, you have the option of putting the second hook on the centre holes to clear the duct for a special installation (duct in front position). -
Page 16: Configuration Options
Residential HRV/ERV Configuration Options In order to configure the different modes on your unit, you may need to move a jumper on the unit’s printed circuit board. This can be done without any special tools following the directions below. Suggestion: it is easiest to do this prior to installation, on a table with the unit on its back. Disconnect the unit power cable to avoid electric shock or damaging the PCB. - Page 17 Residential HRV/ERV 5a) Defrost Modes By default, the HRV/ERV is configured for Normal Defrost, with no jumpers on pin sets 5 and 6. Normal Defrost is optimized for most climate zones. The unit will automatically protect the core from frost build up by periodically switching to high- speed recirculation or exhaust.

Page 25: Measuring And Balancing Airflow
Residential HRV/ERV V. MEASURING & BALANCING AIRFLOW Measure and Balance The installer must measure and balance the airflow brought in from the outside and the exhaust airflow so that the difference between the two is less than 10% of the maximum airflow. - Page 26 Residential HRV/ERV 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 balanced at lower speeds. For the VentZone system, balancing at low speed is recommended.

Page 30: Troubleshooting
Residential HRV/ERV Energy Use: The way your HRV/ERV is installed can make a considerable difference to the electrical ener- gy you use. To reduce HRV/ERV electrical consumption, a fully ducted, self-contained instal- lation is recommended. If you choose a simplified installation that operates your furnace’s air handler for room-to-room ventilation, a low-power furnace with a variable-speed, electron- ically commutated fan motor will reduce your electrical energy consumption and operating costs. - Page 31 Residential HRV/ERV Symptom Possible Causes Solution Wall Dehumidistat is not working • The wall control is not set • For control 611242-FC, ensure properly that the AUTO mode is selected • Outdoor RH is higher than and the target RH level is below the control setpoint the outdoor RH.
