I have a brand new Harman p61 and tried to use it on room mode. I switched it from constant where the room was 75. I set it on 1 (50) to see what would happen. I was expecting it to shut off but it didn't. The sensor is just stretched out from the back of the stove to a table 3 feet away which would be at the same temp. It's in my kitchen which is maybe 10x10 so it maintains heat well. I was expecting it to turn off immediately which it didn't do so I switched back to constant. Does it take some time to recognize the temperature before it reacts or is there something wrong? I never use it but thought I'd try it. Or should the status light go off indicating it's shutting down. I neglected to look at it. And never considered it takes 20 minutes or more to show any signs of shut down. Next time I'll spend more time and check the status light.
