Faqs

How do I install the Honeywell Home TL8230A1003 Programmable Thermostat for the first time?

To install your Honeywell Home TL8230A1003 Programmable Thermostat, first turn off power at the main electrical panel. Loosen the bottom screw to remove the faceplate from the wallplate, then connect wires to the wallplate following the wiring diagram for your heating system. Mount the wallplate to an electrical box with provided screws. Set configuration switches on the faceplate back for your system type, like early start. Reattach the faceplate, remove any screen sticker, and restore power. Ideal location: 5 ft above floor on an inside wall facing the heating system.[1][2]

How do I program the schedule on my Honeywell Home TL8230A1003 Programmable Thermostat?

Programming the Honeywell Home TL8230A1003 Programmable Thermostat is straightforward. Press Pgm to enter programming mode. Use Day button to select days (hold for entire week). Set start times with Hour and Min buttons for each of 4 periods per day, or press Clear to skip. Assign Sun (home) or Moon (away) temperatures.
