This is a new house, there wont be a wall switch to control the furnace fan it will have an HRV. The HRV control should be set to run constantly above a certain humidity level or just have it run all the time and turn off the humidifier completely. Try 10 min fresh air, 50 min re-circulate. Raise all the blinds at least a few inches.

HRV's aren't great at removing moisture despite what your homebuilder tells you they do, it's a Heat Recovery Ventilator, but it does pull some moisture from the air.

EDIT: To add... 34% is prob to high at this temperature and I bet your humidistat is probably off anyways. Mine is almost off by -10% from actual humidity. New houses have a tonne of moisture in them still so having the humidifier off and relying on your house drying out and just having your family breath would be sufficient enough to add humidity for the first winter. It was for me at least when it was this cold.
