How to Fix / Troubleshooting

Safety: Moisture can damage electronics. Avoid wiping with wet cloths.

  • Step 1 – Reduce humidity: Use a dehumidifier or run AC to lower indoor humidity to 40–50%.
  • Step 2 – Improve wall insulation: Seal gaps behind the wall plate and insulate the wall cavity if the thermostat is on an exterior wall.
  • Step 3 – Relocate thermostat: If condensation persists, move GLAS to an interior wall away from cold surfaces.
  • Step 4 – Inspect for damage: If condensation has been present for a long time and GLAS behaves erratically, internal damage may have occurred. Replace the thermostat.
