Heating Settings for Better Thermostat 1.8.0

Heyhey
This morning I updated to Better Thermostat 1.8.0.
So far Ive been using better_thermostat.restore_saved_target_temperature to restore default "heat" temperature and better_thermostat.set_temp_target_temperature to set the thermostate to ECO when Im away.
Looking to the docs this still is the recommended way, but doesnt work anymore.
In the new BT configuration I added two presets (Eco (for heating when Im present) and away (when Im not present)).
Do I change modes this way now:?

action: climate.set_preset_mode
metadata: {}
target:
  entity_id:
    - climate.bt_1
    - climate.bt_2
data:
  preset_mode: away
#or preset_mode: eco

Or is this wrong? Should I use the preset mode "none" for the usual daily heating?
Because if I set it to "none" the UI Card gets red - which looks more like "usual heating" than the color of ECO.
