Thermostat shows E9 and indicates pairing error with Saunier Duval internet gateway or RF bridge

Safety: Turn off power to the gateway if it is mains powered before relocating it.

• Check model: Ensure the gateway or RF bridge is the correct Saunier Duval model compatible with your thermostat.
• Reset gateway: Press and hold the reset or pair button on the gateway for the time specified in the manual to clear previous pairings.
• Bring devices closer: Place the thermostat and gateway within a few meters of each other during pairing.
• Update firmware: Use the app to update firmware on both devices if prompted.

Repeat the pairing process carefully. If E9 continues, the gateway may be defective.
