IV. Signal Lost
In case the RF and WIFI signal lost/disconnected, LED 2 will flicker slowly.
Open Window Detection
When the Open Window detect function is enabled in the parameter setting, the system will automatically stop heating
when it detects a sudden drop of room temperature (2°C in 15 minutes as default). This is normally caused when a
window or door is opened without turning off the heating device.
The device will return to the previous mode of operation after 30mins, then OP disappear. Press any button will exit OWD
function during the heating off period.
Parameter Setting
Under off mode, press and hold SET button and + button for 6s to enter parameter setting. Each press of SET button will
go to next item setting. Adjust the value by pressing + or – button.
