3 What is the difference between an HRV and an ERV? The core in an HRV (Heat Recovery Ventilator) trans- fers heat from one air stream to the other. This is called sensible heat.

16 Operating the ControlAir 15 Plugging in the HRV/ERV energizes the unit. A self test function will be performed every time the HRV/ERV is energized (refer to “Self Test” for more details). After the self test has completed successfully the HRV/ERV will default to Speed 1.
17 Press and hold the fan selection button on the Control Pad. After 5 seconds the control will begin to cycle each mode holding each for 2 seconds. Release the button when the desired mode of operation is reached. Modes of Operation LED Indication OFF No LED’ s illuminated HR V/ER V is off, no controls will initiate operation.

19 AIR SENTRY™ Air Quality Sensor PART NO. 99-109 Connects to RED, GREEN and YELLOW terminals. Use a minimum of three lead 18 gauge low voltage wire.
20 Some models have a built-in dehumidistat (an optional remote wall mount dehumidistat can be installed, see Optional Remote Controls), to control harmful, excess humidity during the heating season . The dehumidis- tat operates in % of RH (relative humidity) with 80 being high and 20 being low.
21 95 MAX Port Specifications The 95 Max Heat Recovery Ventilator (HRV) has been designed to allow the installer to choose between two possible positions on the cabinet for the INDOOR EXHAUST (return from building) port. Illustrations in this manual show standard (side mounted) port loca- tion.
22 Location The HRV/ERV must be located in a heated space where it will be possible to conveniently service the unit. Typically the HRV/ERV would be located in the mechanical room or an area close to the outside wall where the weatherhoods will be mounted.
23 A well designed and installed ducting system will allow theHRV/ERV to operate at its maximum efficiency. Always try to keep duct runs as short and straight as possible.
24 In homes without a forced air furnace, fresh air should be supplied to all bedrooms and living areas, exclud- ing bathrooms, kitchen and utility areas. It should be supplied from high wall or ceiling locations. Grilles that diffuse the air comfortably such as the Techgrille™ are recommended.

26 Simplified Installation Option 1 (Return/Return Method) Note: Option 1 is the pr eferred / r ecommended method when doing a simplified installation. Example diagram only - duct configuration may change depending on model *Unit is normally balanced on HIGH speed with furnace blower ON.
27 Simplified Installation Option 2 (Supply/Return Method) RETURN AIR DIRECT CONNECTION of both the HRV/ERV SUPPLY AIR STREAM and EXHAUST AIR STREAM to the FURNACE COLD AIR RETURN & SUPPLY AIR SIDE Outdoors Cool Air Return NOTES: 1. Furnace blower is required to operate when ventilation from HRV/ERV is required.
28 Fully Dedicated System Example diagram only - duct configuration may change depending on model Please Note: It is the responsibility of the installer to ensure all ductwork is sized and installed as designed to ensure the system will perform as intended.
It is necessary to have balanced air flows in an HRV/ERV. The vol- ume of air brought in from the outside must equal the volume of air exhausted by the unit.
30 Push and turn with slotted screwdriver. Damper automatically locks when pressure is released. When connecting ductwork to the collar, take note where screws are located. Screws should be located no further than 1/2” from outside edge of collar, so as not to impede operation of the damper.
31 1. Inspect Exterior Hoods at least once a month. Make sure exhaust and fresh air supply hoods are not blocked or restricted by leaves, grass, or snow. In win- ter, it is especially important to make sure snow is not blocking the hoods or that frost has not built up on the wire mesh (bird screen).
32 1. Inspect Exterior Hoods at least once a month Make sure exhaust and fresh air supply hoods are not blocked up or restricted by leaves, grass, or dirt. WARNING: Blockage of hoods may cause an imbal- ance. 2. Clean Air Filters Four Times a Year The standard filters equipped with your ERV are removable and washable.
