Maintenance
- Cleaning: Disconnect the heat mat from power before cleaning. Wipe the mat with a damp cloth. Do not use abrasive cleaners or submerge the thermostat in water.
- Storage: When not in use, ensure the mat is clean and dry. Roll it up loosely and store it in a cool, dry place away from direct sunlight.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Heat mat not heating. | Not plugged in; thermostat off; set temperature too low. | Ensure all connections are secure and plugged into a live outlet. Turn thermostat ON. Increase the set temperature above the current ambient temperature. |
| Temperature is inconsistent. | Probe not properly placed; external drafts; large temperature fluctuations in environment. | Ensure the NTC probe is fully inserted into the growing medium and not touching the mat directly. Minimize drafts. The thermostat will cycle to maintain temperature, which is normal. |
| Thermostat display is blank. | No power; thermostat damaged. | Check power connection. Try plugging into a different outlet. If still blank, contact customer support. |
