the minimum operating temperature for the
Aqu@ Scop Advance DCI
for this application is limited by the parameter
h23 to -20°c. the leaving water temperature is always below the limit and the appliance can operate with the boiler
down to temperatures of -20°c. the boiler start-up temperature is determined by
Aqu@ Scop Advance DCI
's
capacity (balance point).
4.2. RooM SEtPoINt CoRRECtIoN
the water setpoint is set for an indoor air temperature of 20°c. if the room setpoint is changed then the water
setpoint is corrected 3° for a radiator configuration and 2° for an underfloor heating configuration per 1 degree of
difference. the correction can be changed using parameter s10, set the parameter to 0 for no correction.
this correction is not used if no room terminal is present.
4.3. RooM AIR tEMPERAtURE AUtoMAtIC CoRRECtIoN
the difference between the room temperature and the room setpoint is continuously monitored and used to correct
the heat curve. a correction factor is calculated using a Pi algorithm. the maximum and minimum possible values
are +10° and -10°. the possible correction factors can be adjusted using parameter s12. the default value is 1,
0 is no correction and 2 corresponds to a correction of +20° /-20°.
