Initial power-up mode

When the thermostat starts up for the first time, all icons are lit for about three seconds before entering ON mode.

ON mode

In ON mode, the current room temperature, plus, minus and status icons (i.e., connection state) are displayed on screen. This mode allows you to adjust the temperature setpoint and switch between OFF and ON.

The icon shows if the setpoint is adjusted manually via thermostat or mobile application, and indicates if the thermostat is in manual mode. It disappears after the thermostat receives the next setpoint via schedule, scene and automation from the mobile application.

Protection mode (OFF mode)

The thermostat activates protection mode (OFF) when you touch the Power button in ON mode. OFF is displayed. If the temperature drops below 8 °C, the thermostat activates the heating output automatically until temperature reaches 8 °C.

In OFF mode, the present room temperature and state icons (i.e., connection state) are displayed. Switch to ON mode by pressing the Power button again.
