on saddle valve.
Verify control circuit wiring.
Check all connections.
Turn the humidistat up all the way. If "Humidity Boost" appears on the
screen the H6062 is calling for humidity. If it does not, the installer might
not have enabled boost and it is possible very cold outdoor temperatures
could be restricting humidity.
Verify that outlet has power.
After verifying other wiring components, turn on furnace fan, turn
humidistat up and down, and listen for solenoid to click.
Verify plumbing connections.
Check for kinks. Verify shut off valve is in open position.
Verify shut off valve is turned on. If a saddle valve is used, verify that needle
pierces water line and then backs out needle to open valve.
Remove cover and verify that water flows into distribution tray.
Verify no obstructions.
Seal with foil tape.
• Reset circuit breaker or check for blown fuse.
• Check that the furnace power is on.
• Check all external wiring connections.
• Check the humidity control setting.
• Verify that pressure switch tubing isn't pinched or obstructed.
• Call a professional heating contractor.
• Keep doors and windows closed.
• Close fireplace damper when not in use.
• Keep exhaust fan running time to a minimum.
• Seal around doors and windows.
• Set damper blade to "winter" position to allow humidification.
• Turn off humidity control and water until condensation is completely
evaporated.
• The H6062 can be set for frost control if outdoor sensor is used. If
already set for window protection. If frost protection is enabled, and you
still get condensation, lower the setting on the H6062.
