How to Program a Honeywell RTH2300B Thermostat
- 1). Press the "Set" button three times until "Set Schedule" shows up on the bottom of the display. You will see the word "Wake" on the display, as well as the days from Monday to Friday.
- 2). Adjust the time that you want to start this period. "Wake" periods are generally run in the morning, but you can set it for any time. Press the "Set" button.
- 3). Move the temperature switch on the bottom of the thermostat to the "Cool" position. Set the temperature for this period with the up and down arrows. Move the switch to "Heat" and set the temperature for that period. Press the "Set" button. You will see the days change to show only Saturday and Sunday.
- 4). Set the time and temperature for the "Wake" period on the weekends using the same process as you did for the weekdays. When you finish these settings, you will see the "Leave" period appear on the screen. Complete the process, both for weekdays and weekends, for the "Leave" period, followed by the "Return" period and the "Sleep" period. If you wish to skip a period, press and hold the "Hold" button for four seconds.
- 5). Press the "Run" button. Your program will now run as long as the temperature switch is in either the "Cool" or "Heat" position.
