Your thermostat is not like a house stat that allows an A/C temp to be set and a heater temp to be set. You have to set the temp for which ever mode you want to use.
The reason the A/C fan blows when you select heat is because you have the fan mode set to 'on.'
Set the fan mode to 'auto' and the A/C fan won't come on with the furnace.
Many people like that feature though as it distributes the warm air more evenly. (warm air rises)
