5.7.7 CALIBRATION
The CALIBRATION menu can calibrate sensors by setting offsets. The parameters are listed in Table 5-27. 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
0
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

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
-
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
