5.7.7 CALIBRATION
The CALIBRATION menu can calibrate sensors by setting offsets. The parameters are listed in Table 5-26. The
parameters are in pairs: the former is the calibrated value and the latter is the calculated value, or the sum of
the measured value and the calibrated value. This value is engaged in the calculation of control need.

Parameters
Default
Description
S602 RTN TEMP K
Calibrated return air temperature. It can be set as a positive or negative value. Use
the up and down buttons to change the setting value, 0.1K at each step
S603 CAL TEMP 25°C
Sum of the calibrated value and measured return air temperature. This value is
compared with the setting value as the system actual temperature and is engaged in
the calculation
S604 RTN HUM
+0.0%
Calibrated return air humidity. It can be set as a positive or negative value. Use the
up and down buttons to change the setting value, 1% at each step
S605 CAL HUM
44.0%
Sum of the calibrated value and measured return air humidity. This value is
compared with the setting value as the system actual humidity and is engaged in
the calculation
S606 DS1 NTC
+0.0K
Calibrated digital scroll 1NTC. It can be set as a positive or negative or positive
value. Use the up and down buttons to change the setting value, 0.1K at each step
S607 CAL DS1
29°C
Sum of the calibrated value and return air humidity measured by digital scroll 1NTC
sensor. This value is engaged in the calculation
S608 DS2 NTC
+0.0K
Calibrated digital scroll 2NTC. It can be set as a positive or negative value. Use the
up and down buttons to change the setting value, 0.1K at each step
S609 CAL DS2
