Thermostat does not respond to mobile app commands even though it shows as online

Safety first: No electrical work is required for this issue.

• Step 1 – Test local control: Confirm that the thermostat responds normally to on‑screen commands. If not, address local control issues first.
• Step 2 – Refresh app: Log out of the iComfort app, close it completely, then log back in. Ensure the app is updated to the latest version.
• Step 3 – Re‑link device: In the app, remove the thermostat from your account and then re‑add it using the pairing instructions on the thermostat.
• Step 4 – Check for multiple users: Ensure other household members are not overriding your commands with their own app sessions.
• Step 5 – Verify router stability: Check router logs for frequent disconnects or reboots that could interrupt cloud communication.
