6.21.9 Setpoint readjustment
Basics of setpoint readjustment
To be able to compensate for temperature deviations resulting from unfavorable sensor
locations, for instance, the setpoint can be readjusted. For setpoint readjustments, 2
correction values must be parameterized: One for the setpoint of 40 °C, and one for the
setpoint of 60 °C. These 2 values define a straight line which delivers the correction
values for all other setpoints.
Setpoint readjustments can be made separately for DHW consumption and the Keep
hot function.
If the consumption setpoint is changed, the LMS14... can automatically change the
keep-hot setpoint as well, if required.
 For that, the keep-hot setpoint on Setpoint keep hot (5460) must be set to OSV (---)
Using the setpoint readjustment, correction values can be parameterized for the
setpoints of 40 °C and 60 °C. These 2 points define a linear readjustment of any keep-
hot setpoints.

8853 Instant WH setpoint
For setpoint readjustments during DHW consumption, the 2 correction values for the
consumption setpoints of 40 °C and 60 °C must be parameterized. If both are set to 0,
there will be no readjustment of the consumption setpoint.

For setpoint readjustments in connection with the Keep hot function, the 2 correction
values for the Keep hot setpoints of 40 °C and 60 °C must be parameterized. If both are
set to 0, there will be no readjustment of the Keep hot setpoint.
