Below are the steps you can take:
1) Set all other desired settings, clock, switch-on time, time display, ECO function activation,...
2) Which part do you want to have in spring mode?
By default the lamp is in summer mode, so you only need to adjust the part to be switched to spring mode.
⚠️ Once these settings are done you don't need to set anything else on the light, unless you want to reset it differently.
