So the fan's on a thermostat? Can you just turn it on manually? I have a little space heater that warms my recording area fairly nicely, but it's too loud to have on to record (unless I'm going direct).
Yes, the thermostat is built into the unit. You can turn heating and cooling on or off manually as well.
It’s this, except mine’s black and pewter, not white and gold.

Incidentally the Blue Air doesn’t have a heater, but it’s a fraction of the price. I have two of them, and use them upstairs because they help with allergies.
