Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater
I just called customer service for the same problem. Push the fan button, which is the MIDDLE BUTTON of the 3 bottom buttons, and the UP ARROW button at the same time, you will see the number 1 on the left of the screen. Press the bottom right button until you see the number 28 on the left, 68 should be on the right. Press the DOWN ARROW until you get to the desired temp, it won't go lower than 50. Then press ok.
