Operating the Thermostat
Manual Controls
- MODE Button: Cycles through system operating modes: Off, Heat, Cool, Auto.
- FAN Button: Cycles through fan operation modes: Auto (fan runs only when heating/cooling) or On (fan runs continuously).
- Up/Down Arrows: Adjusts the temperature setpoint.
Z-Wave Control
Once paired with a Z-Wave hub, you can control the thermostat remotely via your hub's interface or associated mobile application. This includes:
- Changing system mode (Heat, Cool, Auto, Off).
- Adjusting temperature setpoints.
- Setting fan mode.
- Creating schedules and automation rules (functionality depends on your Z-Wave hub).
Maintenance
- Battery Replacement: Replace AA batteries approximately every 2 years, or when the low battery indicator appears on the display. Use high-quality alkaline batteries.
- Cleaning: Wipe the thermostat's exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Firmware Updates: Check the GoControl website or your Z-Wave hub manufacturer's support pages for available firmware updates. The thermostat supports USB firmware upgrades.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Thermostat not powering on. | Dead batteries or no C-wire connection. | Replace batteries or verify C-wire connection and HVAC power. |
| Cannot pair with Z-Wave hub. | Hub not in inclusion mode, thermostat too far from hub, or interference. | Ensure hub is in inclusion mode. Move thermostat closer to hub. Check for Z-Wave network interference. Try excluding and re-including the device. |
| HVAC system not responding. | Incorrect wiring, HVAC power off, or thermostat mode incorrect. | Verify wiring connections. Check HVAC system's circuit breaker. Ensure thermostat is set to the correct system mode (Heat/Cool/Auto). |
| Inaccurate temperature reading. | Thermostat location affected by drafts, direct sunlight, or heat sources. | Relocate thermostat if possible. Allow 15 minutes for sensor adjustment after installation or significant temperature changes. |
