Weather-compensated setpoint shifting(climatic regulation):
The RWF55 can be configured so that weather-compensated setpoint shifting is activated when an LG-Ni1000 outside sensor or a
Pt1000 is connected (see parameter
InP3
).
To take into account the time response of a building, weather-compensated setpoint shifting uses the attenuated outside temperature
rather than the current outside temperature
The minimum and maximum setpoints can be set using the lower setpoint limit
SPL
and the upper setpoint limit
SPH
of the menù
Crtr
.
The system also prevents the lower working range limit
oLLo
and upper working range limit
oLHi
from exceeding/dropping below the
system temperature limits.
The heating curve describes the relationship between the boiler temperature setpoint and the outside temperature. It is defined by 2
curve points. For 2 outside temperatures, the user defines the boiler temperature setpoint that is required in each case. The heating
curve for the weather-compensated setpoint is calculated on this basis. The effective boiler temperature setpoint is limited by the upper
setpoint limit
SPH
and the lower setpoint limit
SPL
.
