Leaving water temperature maximum modulation
ONLY applicable in room thermostat control and when modulation is enabled. The
maximum modulation (=variance) on the desired leaving water temperature
decided on the difference between the actual and desired room temperature, e.g.
3°C modulation means the desired leaving water temperature can be increased or
lowered by 3°C. Increasing the modulation results in better performance (less On/
OFF, faster heat up), but note that depending on the heat emitter, there MUST
ALWAYS be a balance (see the design and selection of the heat emitters) between
the desired leaving water temperature and the desired room temperature.

Weather-dependent cooling allowance
It is possible to disable weather-dependent cooling, meaning the desired leaving
water temperature in cooling operation does NOT depend on the outdoor ambient
temperature and this regardless whether weather-dependent is selected or NOT.
Both for the main leaving water temperature zone as for the additional leaving
water temperature zone, this can be set separately.
