figured this out myself. Ended up with such a statement.
- conditions: >-
{% if is_state ('input_select.ac_studio_mode','off') %}
{{ states('sensor.temperature_lumi_158d0003f0530a')|float > states('input_number.temp_day_upper_threshold')|float }}
{%else%}
{{ states('sensor.temperature_lumi_158d0003f0530a')|float > states('input_number.temp_day_upper_threshold')|float - states('input_number.tolerance')|float }}
{% endif %}
