How to fix air that is too dry with Fantech Fan?
If the air is too dry when using your Fantech Fan, it might be because the dehumidistat control is set too low. Try increasing the desired level of humidity and change the ventilation mode from continuous mode to standby.
Why does the supply air feel cold from my Fantech SHR 2004 Fan?
If the supply air from your Fantech Fan feels cold, it could be due to the location of the supply grilles, which might irritate the occupant. Consider relocating the grilles higher on the walls or under the baseboards, or install ceiling-mounted diffusers or grilles to avoid directly spilling the supply air on the occupant. You could also turn down the HRV supply speed or use a small duct heater (1kW) to temper the supply air. Additionally, ensure that furniture or closed doors aren't restricting air movement in the home. If the outdoor temperature is extremely cold, and 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 there is persistent condensation on window with Fantech SHR 2004?
Persistent condensation on windows when using your Fantech Fan might be due to a few reasons. Try reducing the desired level of humidity by adjusting the dehumidistat control and using continuous exchange mode. If that doesn't work, have a contractor balance the HRV. Also, make sure to open curtains or blinds to improve air circulation near the windows.
How to improve poor air flow in my Fantech Fan?
Poor airflow in your Fantech Fan can stem from several issues. Start by checking and cleaning the exterior hoods or vents if the 1/4" (6mm) mesh is plugged. Remove and clean the filter and core. Ensure indoor grilles are open and unblocked. Have an electrician check the power supply voltage. Inspect duct installation for restrictions. Increase the fan speed, and if these steps don't resolve the issue, have a contractor balance the HRV airflow or reconnect any disconnected ducting.
What to do if Fantech SHR 2004 air is too humid?
If the air from your Fantech Fan is too humid, it might be due to several reasons, including the dehumidistat control being set too high, a sudden change in temperature, storing too much wood inside, a dryer vent exhausting inside, poor air circulation near windows, an out-of-balance HRV, or a closed well-sealed basement door. To address this, reduce the desired level of humidity and use continuous exchange mode. Wait for the outside temperature to stabilize, and consider heating to improve the situation. Store most of your wood outside, arrange an outside vent for the dryer, open curtains or blinds, balance HRV airflows, and open the basement door or install a grill.
Why are my Fantech SHR 2004 Fan's HRV and/or ducts frosting up?
If your Fantech Fan's HRV and/or ducts are frosting up, have an HVAC contractor balance the HRV airflows. Note that minimal frost build-up is expected on cores before the unit initiates defrost cycle functions.
What to do about condensation or ice build up in insulated duct to the outside of my Fantech SHR 2004 Fan?
To address condensation or ice buildup in the insulated duct of your Fantech Fan, tape and seal all joints to ensure a complete vapor barrier. Also, tape any holes or tears in the outer duct covering and ensure the vapor barrier is completely sealed.
Why does supply air feel cold from my Fantech SHR 2004 Fan?
If the supply air from your Fantech Fan feels cold, reposition the supply grilles high on the walls or under the baseboards, and install ceiling-mounted diffusers to avoid direct airflow on occupants. Reduce the HRV supply speed. If supply air is ducted into the furnace return, run the furnace fan continuously. Also, ensure furniture or closed doors aren't restricting air movement.
How to stop persistent condensation on window with my Fantech Fan?
To fix persistent condensation on your window when using a Fantech Fan, reduce the humidity level and use continuous exchange mode. Open curtains or blinds to improve air circulation. If the problem continues, have a contractor balance the HRV.
How to improve poor air flows in my Fantech SHR 2004?
To improve poor air flows with your Fantech Fan, begin by cleaning the exterior hoods or vents and removing and cleaning the filter and core. Ensure indoor grilles are open and not blocked. Have an electrician check the power supply voltage. Check the duct installation and increase the HRV speed. If the issue persists, have a contractor balance HRV airflows or reconnect ducting.
