C) System water temperature limits in HEATING*
These define the temperature limits (minimum and maxi-
mum) that can be requested from the circuit and never
exceeded.
In the figure the minimum limit is 30°C and the maximum is
40°.
Between 30 and 40°C the water temperature will be able to
vary based on the trend in outside temperature.
For systems configured with mixed zones, the limits for the
SYSTEM curve and ZONE curve must be selected.
B) Room temperature influence in HEATING*
Function only active if the N-THC room control units (acces-
sory) are installed.
The compensation curve determines the heating water tem-
perature; this may then be corrected based on the difference
between the desired room set point and the actual room tem-
perature.
The correction made to the water temperature depends on
the “Room Authority” coefficient.
The higher the value of the Room Authority the higher the
correction to the system water temperature, and vice-versa.
This allows the water temperature to adapt quickly to
changes in the conditions inside the room.
The function can only be ENABLED if the A5 room controller
is positioned in the room and used to measure the reference
temperature.
Set authority values for the SYSTEM equal to or greater than
those for zones LT1.
Enabling room temperature influence on SYSTEM deviates
the calculated heat pump water temperature set point.
Enabling room temperature influence on ZONE LT1, deviates
the calculated water temperature set point to the system,
controlled by the mixing valve.
