[3] Weather dependent set point
When weather dependent operation is active, the leaving water temperature is determined automatically
depending on the outdoor temperature: colder outdoor temperatures will result in warmer water and vice
versa. The unit has a floating set point. Activating this operation will result in a lower power consumption
than use with a manually fixed leaving water set point.
During weather dependent operation, the user has the possibility to shift up or down the target water
temperature by a maximum of 5°C. This "Shift value" is the temperature difference between the
temperature set point calculated by the controller and the real set point. E.g. a positive shift value means
that the real temperature set point will be higher than the calculated set point.
It is advised to use the weather dependent set point because it adjusts the water temperature to the actual
needs for space heating. It will prevent the unit from switching too much between thermo ON operation
and thermo OFF operation when using the remote controller room thermostat or external room
thermostat.
Note :
During this operation, instead of showing the water temperature set point, the controller shows the shift
value which can be set by the user.
[3-00]
Low ambient temperature (Lo_A): low outdoor temperature.
[3-01]
High ambient temperature (Hi_A): high outdoor temperature.
[3-02]
Set point at low ambient temperature (Lo_Ti): the target outgoing water temperature when the
outdoor temperature equals or drops below the low ambient temperature (Lo_A).
Note that the Lo_Ti value should be higher than Hi_Ti, as for colder outdoor temperatures (i.e. Lo_A)
warmer water is required.
[3-03]
Set point at high ambient temperature (Hi_Ti): the target outgoing water temperature when the
outdoor temperature equals or rises above the high ambient temperature (Hi_A).
Note that the Hi_Ti value should be lower than Lo_Ti, as for warmer outdoor temperatures (i.e.
Hi_A) less warm water suffices.
Note :
If by mistake the value of [3-03] is set higher than the value of [3-02], the value of [3-03] will always be
used.
