Heating Curve means let the system adjust the outlet water temperature based on the ambient temperature by continually
monitoring and adjusting in opposite direction with the current ambient temperature levels according to a pre-set curve,
to optimum comfort levels based on the changing heat demand,insulation levels,etc.
In a way, when it is colder (warmer) outside, house will need a higher (lower) temperature water to keep the same air
temperature in the house. Thus we can set a curve for the unit to follow, to let the unit adjust its set temperature for
heating operation
according to the set curve and actual ambient temperature
.
This function can be turned ON/OFF by adjusting the value of this parameter.

Room Temp. Effect On Heating

Parameter No.
Meaning Range Default Value
If room temperature sensor is connected, "Set Room Temperature" in "Temperature Parameter" under "Basic Operation"
is set, and this "Room Temp. Effect On Heating Curve" is ON, unit will adjust the set water temperature (a set value or
calculated value via heating curve), according to the difference between actual room temperature and ideal room
temperature.
For example, if current water set temperature calculated according to the
heating curve is
35 ℃ :
If actual room temperature is 27
℃ ,
while
"
Set Room Temperature" is set to
22 ℃ ,
then the unit will deduct
(27 ℃ -22 ℃ )=5 ℃
from water set temperature
,
which means unit will take
30 ℃
as the final set temperature.
