What to do if I see a flashing light on my Lifebreath HRV 155 MAX 2019 Fan timer or main control?
A flashing light usually indicates a wiring, voltage, or communication error. Try cycling the power by turning the unit off and disconnecting it for 30 seconds, then reconnect and turn it back on. If the problem continues, it is recommended to contact your service contractor.
Why are my Lifebreath HRV 155 MAX 2019 Fan's humidity levels too high, and condensation is appearing on the windows?
High humidity and condensation can occur if: * The dehumidistat is set too high. * The HRV isn't sized for a hot tub or indoor pool. * There's unvented moisture from a crawl space. * Moisture remains in washrooms and kitchens. * It's spring or fall, with humid days. * The HRV speed is too low. To address this: * Lower the dehumidistat setting. * Cover pools and hot tubs when not in use. * Avoid drying clothes indoors or storing wood inside. * Vent the crawl space and add a vapor barrier. * Ensure effective ventilation in washrooms, using a fan if needed. * Understand that some condensation is normal during seasonal changes, but the HRV will maintain air quality.
What to do if my Lifebreath Fan has poor airflow?
Poor airflow can be caused by several factors: * Blocked mesh on the outside hood. * Plugged filters. * Obstructed core. * Closed or blocked house grilles. * Closed dampers (if installed). * Poor power supply. * Restricting ductwork. * Improper speed control setting. * Improperly balanced HRV airflow. To resolve this: * Clean exterior hoods or vents. * Remove and clean the filter. * Remove and clean the core. * Check and open grilles. * Open and adjust dampers. * Have an electrician check the supply voltage. * Check duct installation. * Increase the speed of the HRV. * Have a contractor balance the HRV.
Why does the supply air from my Lifebreath HRV 155 MAX 2019 feel cold?
Cold supply air can be due to the location of supply grilles causing irritation or extremely cold outdoor temperatures. Try locating the grilles high on the walls or under the baseboards, or installing ceiling-mounted diffusers or grilles to avoid direct airflow on occupants. You could also turn down the HRV supply speed or use a small duct heater (1kW) to temper the supply air. Ensure furniture placement or closed doors aren't restricting air movement. If the supply air is ducted into the furnace return, the furnace fan may need to run continuously to distribute ventilation air comfortably.
What to do if my Lifebreath Fan's dehumidistat is not operating?
If the dehumidistat isn't working, it could be due to the outdoor temperature being above 15°C (59°F), an improper low voltage connection, or an external low voltage short caused by a staple or nail. The dehumidistat functions normally above this temperature. Check that the correct terminals have been used and inspect the external wiring for shorts. Also, ensure the dehumidistat is set to the desired setting.
Why are the humidity levels too low in my house with a Lifebreath HRV 155 MAX 2019?
Low humidity levels can be caused by a dehumidistat control set too low, the blower speed of the HRV being too high, the lifestyle of the occupants, or improperly balanced HRV airflows. You can try setting the dehumidistat higher, decreasing the HRV blower speed, adding humidity using humidifiers, or having a contractor balance the HRV airflows.
What causes condensation or ice buildup in the insulated duct of my Lifebreath HRV 155 MAX 2019 Fan to the outside?
Condensation or ice buildup in the insulated duct can be caused by an incomplete vapor barrier around the insulated duct or a hole/tear in the outer duct covering. To fix this, tape and seal all joints, tape any holes or tears in the outer duct covering, and ensure the vapor barrier is completely sealed.
Why are my HRV and/or ducts frosting up with my Lifebreath HRV 155 MAX 2019?
HRV and/or ducts frosting up can be caused by improperly balanced HRV airflows or a malfunction of the HRV defrost system. To address this, have an HVAC contractor balance the HRV.
Why is there excess water in the bottom of my Lifebreath Fan HRV?
Excess water in the bottom of the HRV can be caused by plugged drain pans, an improper connection of the HRV's drain lines, the HRV not being level, obstructed drain lines, or the HRV heat exchange core not being properly installed. Look for obstructions or kinks in the drain line.
What causes excessive vibration in my Lifebreath HRV 155 MAX 2019 Fan?
Excessive vibration can be caused by dirt on the fan wheels. It is recommended to have a contractor service the HRV.

The Lifebreath Heat Recovery Ventilator (HRV) is an indoor air system designed to improve air quality and energy efficiency in modern, tightly constructed buildings. Its primary function is to continuously supply fresh outdoor air while exhausting an equal volume of stale indoor air, thereby ensuring a healthy indoor environment year-round. This process also facilitates energy savings by reducing the heating and cooling demands on a building's HVAC system.
The HRV operates by transferring heat between the incoming fresh air and the outgoing stale air through a heat recovery core. During colder months, the warmer exhaust air preheats the cooler incoming fresh air, while in warmer months, the cooler exhaust air precools the incoming air. This heat exchange mechanism helps maintain a comfortable indoor temperature while minimizing energy loss. The unit automatically cycles through a defrost mode when outdoor temperatures drop below freezing to prevent frost buildup on the core, ensuring continuous operation.
Upon power-up, the HRV initiates a self-test function, cycling through available speeds and testing damper motor operation before resuming its selected mode. The system is designed to mitigate high indoor humidity during cooler winter months by exchanging humid indoor air with drier outdoor air.
The HRV offers various operating modes and fan speeds to allow users to customize ventilation rates based on their home's needs and personal preferences. These modes are typically controlled via a main wall control, with some features potentially varying by model.
Regular maintenance is crucial to ensure the HRV operates efficiently and effectively. The manual outlines several procedures with recommended intervals:
Safety warnings emphasize disconnecting power before any cleaning or servicing to prevent electrical shock and ensuring proper grounding of the unit. Users are also advised that blockage of hoods can cause an imbalance in the system.
