Leaving water temperature overshoot temperature
This function defines how much the water temperature may rise
above the desired leaving water temperature before the compressor
stops. The compressor will startup again when the leaving water
temperature drops below the desired leaving water temperature.
This function is ONLY applicable in heating mode.

Leaving water temperature compensation around 0°C
In heating operation, the desired leaving water temperature is locally
increased around an outdoor temperature of 0°C. This
compensation can be selected when using an absolute or a weather
dependent desired temperature (see illustration below). Use this
setting to compensate for possible heat losses of the building due to
the evaporation of melted ice or snow (e.g. in cold region countries).

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 (refer to the design and
selection of the heat emitters) between the desired leaving water
temperature and the desired room temperature.

Weather dependent cooling allowance
ONLY applicable for RHBX and RHVX. 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.

Temperature ranges (room temperature)
ONLY applicable in room thermostat control. In order to save energy
by preventing overheating or undercooling the room, you can limit
the range of the room temperature, both for heating and/or cooling.
NOTICE
When adjusting the room temperature ranges, all desired
room temperatures are also adjusted to guarantee they are
between the limits.
