I read some people were having problems with the ductsats. They may have faulty units, but I think they're just trying to use them like a regular thermostat.
The ductstat is designed as a thermostat for a duct-booster fan, which turns on when the "adjusting air" temp changes. The operation is backwards from what you would expect.
In "cooling" mode, the ductstat is actually waiting for the temp to get lower before turning on because it's designed to boost airflow from a central AC when it senses the AC has been turned on. In "heat" mode, it's looking for an increase in temp to boost flow.
If you want to cool your room with the ductstat, set it to "heat". If you want to heat it, set it to "cool".
Basically, you get a nice heat/cool thermostat that handles up to 5A. Not sure what heaters you'll find on 120V that run under 5A, but you can always trip a relay with it. A baseboard heater therm would probably work better for heating anyway.
