Does my furnace motor need to run at all times while in the auto mode?
My installer told me the furnace motor has to be on run, not auto, while my GSHH3K is in the auto mode. Is this the case?
Thank you for your question on the GSHH3K. For best performance and to get the most out of your unit, it would be recommended that your furnace be running for maximum benefits.

We have a GSHH3K in our earth-sheltered home and are very happy with the product. We would like to have a spare fan powered by a 12vdc motor ...
...for a future time when we go off the grid (either by choice or otherwise) Is that a part you might consider providing in the future?

Does the unit provide positve pressure inside the home? Would it be considered a makeup air unit for direct vent appliances (assume outdoor temp +32F)
I have a newer home built in 2010. I'm interested to know if I require an additional make up air unit to provide "positive" pressure inside the home, so that the air to air unit, or other direct vent appliances do not cause a problem with depressurizing the house. I have a Geothermal furnace, so that is not a concern, however the various powered bath vents and range hood and a direct vent hot water heater do exhaust air with out a direct means of replacing it. Is this unit designed to provide a slight positive pressure in the home so that the occasion use of a powered vent does not draw air thru window or other unfiltered cracks in the building envelope?
