Honeywell RTH230B user manual

To get your Honeywell RTH230B thermostat to work, follow these steps:
1. Turn off power: Before starting any work, turn off the power at the circuit breaker. This is important for your safety.
2. Remove your existing thermostat: Take off the cover and remove the old thermostat from the wall, but be careful not to damage any wires.
3. Label the wires: If the wiring is not already labeled, use masking tape or a sticker to label each wire with the corresponding terminal letter. This will make it easier to connect the wires to your new thermostat.
4. Mount the new thermostat: Use the provided screws and anchors to mount the new thermostat base to the wall. Make sure it is level and securely attached.
5. Connect the wires: Match the labeled wires to the appropriate terminals on the new thermostat base. Use a screwdriver to secure them in place.
6. Set the switch position: On the back of the thermostat, there is a switch that should be set to match your heating/cooling system (heat pump, gas/oil furnace, electric furnace). Refer to the installation manual or contact a professional if you are unsure.
7. Attach the thermostat cover: Snap the thermostat cover onto the base and ensure it is securely in place.
8. Restore power: Turn the power back on at the circuit breaker.
9. Set the program: Follow the setup instructions in the thermostat manual to program your desired temperature settings and schedule.
10. Test the thermostat: Verify that your thermostat is now functioning correctly. You can do this by adjusting the temperature and seeing if your heating or cooling system responds accordingly.
If you encounter any difficulties or are unsure about any step, it is advisable to consult the user manual or contact Honeywell's technical support for assistance.

To wire the Honeywell RTH230B thermostat, you will need to follow these steps:
1. Turn off the power to your heating/cooling system at the circuit breaker.
2. Remove the old thermostat from the wall by unscrewing the mounting plate.
3. Take note of the wires connected to the old thermostat and their corresponding labels (e.g., R, G, Y, W, etc.). If there are no labels, use a digital camera or smartphone to take a picture of the wiring for reference.
4. Using a small screwdriver, loosen the terminal screws on the RTH230B thermostat and remove the face plate.
5. On the back of the faceplate, locate the wiring terminals. They should be labeled with the letters typically associated with the wire colors (e.g., R for red, G for green, Y for yellow, W for white, etc.).
6. Match the wires from your old thermostat to the corresponding terminals on the RTH230B thermostat. Gently insert the wires into the appropriate terminals and tighten the screws securely.
7. Once all the wires are connected, attach the faceplate back onto the mounting plate and secure it in place with the screws.
8. Turn the power back on at the circuit breaker and test the thermostat to ensure it is working properly.
Note: If you are not comfortable with electrical wiring or have any doubts, it is recommended to consult a professional electrician to install the thermostat for you.
