Step-by-Step Setup

  1. Turn off boiler power: Switch off power to your heating system.
  2. Install relay near boiler: The relay connects to your boiler's thermostat terminals. Mount it near the boiler.
  3. Wire the relay: Connect the relay to your boiler's on/off thermostat wires (typically two wires from existing thermostat location).
  4. Power the relay: Connect the relay to power (it can use boiler power or a separate outlet).
  5. Install thermostat batteries: Insert 3 AAA batteries into the thermostat unit.
  6. Position the thermostat: Place in a central location, away from heat sources or drafts. Can be wall-mounted or freestanding.
  7. Download Netatmo Energy app: Install and sign in to your account.
  8. Add the thermostat: Tap "+" and follow the pairing process to link thermostat and relay.
  9. Connect to Wi-Fi: Enter your network credentials when prompted.

Troubleshooting

  • Relay not connecting to thermostat: Ensure both are powered. Move thermostat closer during initial pairing. Reset relay by pressing its button for 10 seconds.
  • Boiler not firing: Check relay wiring. Verify boiler's thermostat terminals are correct. Ensure relay LED shows it's signaling the boiler.
  • Temperature reading inaccurate: Move thermostat away from heat sources, direct sunlight, or exterior walls. Allow time to acclimate to new location.
  • Schedule not followed: Check that auto-adapt isn't overriding. Verify schedule is saved correctly. Ensure time zone is set properly.
  • Batteries draining fast: Normal battery life is 2 years. Weak signal to relay can drain batteries faster. Move thermostat closer to relay.
