This setting can be activated by app only, and not manually.
Setting the ‘antifreeze’ mode will automatically apply to the devices in the same room: for example, setting a radiator to ‘antifreeze’ in a room with paired Smart Valves, a Smart Thermostat or another radiator, all devices will follow the same setting (and vice versa).
To set the ‘antifreeze’ mode, the steps in the app are:
. select the tab for the room from the main menu screen
. select the ‘power’ symbol
. the next screen will have a grey background with a temperature setting of 5.0°.
The ‘antifreeze’ mode can be deactivated manually, touching the ‘+’ or ‘–‘ key on the keypad once will cause the white LED to flash, while touching it a second time, will block it, reactivating all of the devices that are paired with the same room.
