On version 2 of the iQ Plus (the current version), frost is an operating mode. You can select it by pressing “M” to skip through the modes on the control panel, or by changing mode on the app. Frost mode is set to 7 °C and is not adjustable. Anti-frost intervals are not available through the program.
On iQ Plus version 1, frost can be toggled on/off in the main menu. When enabled, it operates in standby mode, engaging the heating element if the temperature drops below 5 °C.
