Thermostat and Smart Controls in the DC Area

Most smart thermostat Wi‑Fi issues come from signal or setup problems. Typical causes are weak signal at the thermostat, incorrect password, recent router/SSID changes, or a 2.4 GHz vs 5 GHz mismatch. Power or wiring can also interrupt pairing. Appleton Campbell installs and replaces thermostats and diagnoses smart controls and zoning in Warrenton and nearby areas.

• Restart the thermostat and router.
• Use the 2.4 GHz band if required.
• Re-enter the exact Wi‑Fi name and password.
• Improve signal or add an extender; then retry pairing.
