In warmer weather, turn the dial to the highest setting; decrease the setting when the weather gets colder. In winter, set the dehumidifier just low enough to avoid condensation on the windows.
One of the additional benefits of the VanEE ERV that we deliver to our customers is the Platinum control. If you are using an HRV, a good rule of thumb would be to set your humidity to 30% in the winter and then monitor your humidity.
As a general rule of thumb, you should set your system’s dehumidifier at 25% to 50% depending on the temperature to keep condensation at bay. For example, 50 percent is the maximum relative humidity you should have when the outside temperature is between -11 degrees Celsius and 18 degrees Celsius.
To ensure your home is well ventilated and maintains good air quality, your HRV and ERV should be running continuously. Many HRV fans can run at low, medium, or high speeds depending on ventilation needs.
We recommend that our customers use their HRV systems anytime all windows and doors in their home are closed, but the system should shut down when you open them again to conserve energy to save.
In winter, set the dehumidifier just low enough to avoid condensation on the windows. Do not turn off or unplug your HRV. This can lead to high humidity, which can lead to mold growth and unhealthy living conditions.
Ideally, a home should have a humidity level of around 45%. If it falls below 30%, it is far too dry, and if it is above 50%, the high humidity can become uncomfortable. If the humidity in your home stays around 45%, your living environment will be cleaner, safer, healthier and more comfortable.
In short, you should turn off HRV humidity control when the oven is not being used on the heat setting. You’ve noticed that you open the windows in the off-season, which passively adds significant fresh air and naturally dries the warm air in the house.
Frozen HRV condensate lines
A heat recovery fan can also freeze. In an HRV core, moisture can condense on the cold, impermeable membrane. That’s why HRVs have a floor drain and condensate line to carry away the liquid water. And this is where the trouble happens.
An HRV is an effective, energy-efficient and healthy way to control humidity in your home in winter, but Your HRV doesn’t remove condensation from your windows, it removes excess moisture in the air .
During the heating season, the HRV absorbs heat from the exhaust air and uses it to preheat the incoming fresh air. During the cooling season, an HRV can reverse this heat exchange process by removing some of the heat from the incoming air and transferring it to the outgoing air.
To verify that it works, HRV should turn on automatically when the RH settings are turned down below the normal range without operating any other switches or controls.
