INTRODUCTION Table of Contents HRV - Aluminum Core A Heat Recovery Ventilator (HRV) is designed to provide fresh air into a building while exhausting an equal amount of stale air. During the winter months, the incoming cold fresh air is warmed by utilizing the heat recovered from the stale air before it is exhausted to the outdoors.
ERV Questions & Answers What is the difference between an HRV and an ERV? and damp situation. In fact, about 2/3 of the energy used by the air conditioner system is to remove moisture. Therefore, when ventilating in the summer, less moisture brought into the home means less work for the air conditioner, and energy savings for you. The core in an HRV (Heat Recovery Ventilator) transfers heat from one air stream to the other. This is called sensible heat.

FUNCTION & CONTROL Operating the ControlAir 15 Self Test 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. This is the factory default setting. Follow the instructions found on the HRV/ERV door to select desired mode and speed, or refer to the instructions found on the following page.
To select mode of operation for ControlAir 15 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 HRV/ERV is off, no controls will initiate operation. Standby / On Steady Green LED and Yellow LED to indicate speed HRV/ERV will run at speed selected in ventilation mode.

USING THE DEHUMIDISTAT 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 dehumidistat operates in % of RH (relative humidity) with 80 being high and 20 being low. The average person is comfortable between 30-45%. exceeds the set point on the control. Once the humidity in the house is reduced, the HRV/ERV will revert back to its previous setting.

INSTALLATION 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.
INSTALLING AIR DUCTS To minimize air flow restriction, the flexible insulated duct that connects the two outside weatherhoods to the HRV/ERV should be stretched tightly and be as short as possible. A well designed and installed ducting system will allow the HRV/ERV to operate at its maximum efficiency. Always try to keep duct runs as short and straight as possible. See Installation Diagrams for various installation options. Twisting or folding the duct will severely restrict air flow.
SUPPLY AIR DUCTING Dampers and Grilles In homes without a forced air furnace, fresh air should be supplied to all bedrooms and living areas, excluding 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. The use of balancing dampers and/or adjustable grilles to balance the flow rates into various rooms is recommended. We suggest TECHGRILLE™ air diffusers.

Example diagram only - duct configuration may change depending on model Fully Dedicated System 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. All air movement devices have a performance curve. The amount of air (CFM) that an HRV/ERV will deliver is directly related to the total external static pressure (E.S.P.) of the system.
PITOT TUBE AIR FLOW BALANCING It is necessary to have balanced air flows in an HRV/ERV. The volume of air brought in from the outside must equal the volume of air exhausted by the unit.
BALANCING COLLAR INSTRUCTIONS 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.
Maintenance Routine for HRV (for ERV, see following page) 1. Inspect Exterior Hoods at least once a month. 6. Clean Duct Work if Required Make sure exhaust and fresh air supply hoods are not blocked or restricted by leaves, grass, or snow. In winter, 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). The duct work running to and from the HRV may accumulate dirt. Wipe and vacuum the duct once every year.
Maintenance Routine for ERV (for HRV, see previous page) 1. Inspect Exterior Hoods at least once a month 5. Clean Duct Work if Required 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 imbalance. The duct work running to and from the ERV may accumulate dirt. Wipe and vacuum the duct once every year. You may wish to contact a Heating/Ventilation company to do this. 2. Clean Air Filters Four Times a Year 6.
TROUBLESHOOTING YOUR HRV/ERV SYSTEM SYMPTOM CAUSE SOLUTION Poor Air Flows • 1/4” (6 mm) mesh on the outside hoods is plugged • filters plugged • core obstructed • house grilles closed or blocked • dampers are closed if installed • poor power supply at site • ductwork is restricting HRV/ERV • improper speed control setting • HRV/ERV airflow improperly balanced • clean exterior hoods or vents • remove and clean filter • remove and clean core • check and open grilles • open and adjust dampers • have elec
Technical Bulletin When using the ControlAir 15 relay contacts to initiate blower operation on a furnace, certain thermostats will initiate the outdoor cooling condenser when R and G are closed. Use this wiring configuration to stop the ControlAir15 relay contacts from initializing the condenser unit. This problem can occur at the thermostat because the Y terminal is connected to the G terminal internal to the stat.
