How to fix air that is too dry with my Fantech VHR 2005 R Fan?
To resolve air that is too dry with your Fantech Fan, increase the desired humidity level and change the ventilation mode from continuous to standby. If the issue remains, have a contractor balance the HRV airflows.
What to do if LED is flashing on Fantech VHR 2005 R Fan?
If the LED on your Fantech Fan is flashing, it indicates that no power is being transmitted to the control board. First, make sure the unit is plugged in. If it is, the transformer may need replacing.
Why is Fantech VHR 2005 R air too dry?
If the air from your Fantech Fan is too dry, it may be because the dehumidistat control is set too low. Increase the desired level of humidity and change the ventilation mode from continuous mode to standby.
How to fix condensation or ice build up in insulated duct to the outside of Fantech Fan?
If you notice condensation or ice build-up in the insulated duct to the outside of your Fantech Fan, it might be caused by an incomplete vapor barrier around the insulated duct. In this case, tape and seal all joints. Another cause can be a hole or tear in the outer duct covering, tape any holes or tears made in the outer duct covering and ensure that the vapor barrier is completely sealed.
What to do if Fantech Fan HRV and/or Ducts frosting up?
If your Fantech Fan's HRV and/or ducts are frosting up, it could be due to improperly balanced HRV air flows, have an HVAC contractor balance the HRV airflow. Note that minimal frost build-up is expected on cores before unit initiates defrost cycle functions.
Why is my Fantech Fan supply air feels cold?
If the supply air from your Fantech Fan feels cold, it could be due to the location of the supply grilles. Locate the grilles high on the walls or under the baseboards, install ceiling-mounted diffuser or grilles so as not to directly spill the supply air on the occupant. You can also turn down the HRV supply speed. 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 Fantech VHR 2005 R has persistent condensation on window?
If you notice persistent condensation on your window when using the Fantech Fan, it could be due to a few reasons. Try reducing the desired level of humidity, combining this step with the use of continuous exchange mode. Also, ensure good air circulation near windows by opening curtains or blinds. If the issue continues, have a contractor balance the HRV.
Why is my Fantech VHR 2005 R Fan air too humid?
Several factors can cause your Fantech Fan to produce air that is too humid. First, reduce the desired level of humidity if the dehumidistat control is set too high and combine this with the use of continuous exchange mode. If there has been a sudden change in temperature, wait until the outside temperature stabilizes. Ensure that you store a majority of your wood outside. Check that the dryer vent is exhausting outside and that there is good air circulation near windows (open curtains or blinds). If you have a well-sealed basement door, open it or install a grill on the door. Finally, a failed damper system may be stuck in recirculation mode, so have a contractor verify the damper system.
What to do if Fantech VHR 2005 R has poor air flows?
If your Fantech Fan has poor air flows, several factors could be responsible. Start by cleaning the exterior hoods or vents if the 1/4" (6mm) mesh on the outside hoods is plugged. Also, remove and clean the filter and core. Ensure indoor grilles are open and not blocked. If these steps don't resolve the issue, have an electrician check the power supply voltage. Check the duct installation and increase the speed of the HRV. If the problem persists, have a contractor balance the HRV airflow or reconnect any ducting that has fallen down or been disconnected from the HRV.
What to do if Fantech VHR 2005 R Fan 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.
