﻿The "Summer" or "Winter" state preset via the object "Summer / winter switch-over" is stored internally in the device and is restored after a device reset (voltage return). The parameter "Operating mode after ETS programming operation" defines which operating mode is active after ETS commissioning.

*summer operation*: In this setting, the device activates summer operation after an ETS programming operation. This overwrites the value saved internally in the device.

*winter operation*: In this setting, the device activates winter operation after an ETS programming operation. This overwrites the value saved internally in the device.

*no change (saved operating mode)*: In this configuration, the device activates the most recently saved operating mode.
