5. Installation/Setup

5.1 Tools Required

• Screwdriver
• Wire Strippers (if necessary)

5.2 Mounting Location

Choose a location on an interior wall, approximately 5 feet (1.5 meters) above the floor, away from drafts, direct sunlight, and heat sources (e.g., lamps, appliances, fireplaces). Avoid locations near exterior doors or windows.

5.3 Wiring Instructions

1. Disconnect power to the heating system at the main fuse or circuit breaker panel before proceeding.
2. If replacing an old thermostat, carefully remove it and note the wiring connections. Typically, a heating-only system uses two wires (R and W).
3. Mount the new wallplate to the wall using the provided screws. Ensure it is level.
4. Connect the system wires to the appropriate terminals on the new thermostat. This thermostat is designed for 24 Volt wired systems. Refer to your heating system's manual for specific wiring diagrams if unsure.
5. Secure the thermostat unit to the wallplate.
6. Restore power to the heating system at the main fuse or circuit breaker panel.

6. Operation

The M30 thermostat features a simple lever control for setting the desired temperature.

6.1 Setting the Temperature

• Locate the temperature setting lever on the front of the thermostat.
• Slide the lever to the left or right to align the red indicator with your desired temperature on the Fahrenheit (50-90) or Celsius (10-32°C) scale.
• For heating, set the lever to a temperature higher than the current room temperature to activate the heating system. Set it lower to deactivate the heating system.
• The upper slider also includes an 'OFF' position to completely turn off the heating system.

7. Maintenance

The White-Rodgers M30 thermostat requires minimal maintenance.

• Cleaning: Periodically wipe the exterior of the thermostat with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Batteries: This thermostat does not require batteries as it operates on a wired AC/DC power source.

8. Troubleshooting

8.1 Heating System Not Responding

• Ensure the thermostat lever is set to a temperature above the current room temperature.
• Check that the upper slider is not in the 'OFF' position.
• Verify that the power to the heating system is on at the main fuse or circuit breaker panel.
• Inspect wiring connections at the thermostat and heating system for looseness or corrosion (with power disconnected).

If issues persist after performing these checks, contact a qualified HVAC technician for further assistance.
