TROUBLESHOOTING

Solutions

Causes

Problem

Dehumidistat control is set too low

Dehumidistat control is set too high

Sudden change in temperature

Storing too much wood for heating

Dryer vent exhaust is inside home

Poor air circulating near windows

Well sealed basement door is closed

Improper adjustment of dehumidistat con-
trol

Air is too dry

Air is too humid

Persistent condensation
on window

Increase the desired level of humidity. Change ventilation mode from
continuous mode to standby.

Balance HRV

Reduce the desired level of humidity. Combine this step with use of con-
tinuous exchange mode.

Wait until outside temperature stabilizes (winter). Heating will also
improve situation.

Store a majority of your wood outside. Even dried, a cord of wood con-
tains more than 20 gallons of water.

Arrange outside vent for dryer.

Open curtains or blinds. Bay or bow windows may require mechanical

method.

Balance HRV

Open the door or install a grill on the door.

Reduce the desired level of humidity. Combine this with the use of con-
tinuous exchange mode.
Balance HRV

-Clean exterior hoods or vents
-Remove and clean filter
-Remove and clean core
-Check and open grilles
-Have electrician check supply voltage at house
-Check duct installation
-Increase the speed of the HRV/ERV
-Have contractor balance HRV/ERV

-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 (eg. Over a sofa)

-Turn down the HRV/ERV supply speed. A small duct heater (1kw)

could be used to temper the supply air

-Placement of furniture or closed doors is restricting the movement of

air in the home

-If supply air is ducted into furnace return, the furnace fan may need to

run continuously to distribute ventilation air comfortably

-Note: minimal frost build-up is expected on cores before unit initiates

defrost cycle functions

-Have HVAC contractor balance the HRV

-Tape and seal all joints
-Tape any holes or tears made in the outer duct covering
-Ensure that the vapor barrier is completely sealed.

-1/4” (6mm) 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

Poor Air Flows

-Poor location of supply grilles, the airflow

may irritate the occupant

-Outdoor temperature extremely cold

Supply air feels cold

-HRV air flows are improperly

balanced

-Malfunction of the HRV defrost

system

HRV and / or Ducts
Frosting up

-Incomplete vapor barrier around

insulated duct

-A hole or tear in outer duct covering

Condensation or Ice
Build Up in Insulated
Duct to the Outside

HRV out of balance
