'1' when the measured value is outside the Temperature alert values defined
by holding registers 13 and 14
0—1
0 = Temperature measurement OK

values. Set to '1' when the measured temperature is outside limit range
values defined by holding registers 11 and 12
0—1
0 = Temperature range OK
1 = Temperature range too low/high
5 Humidity, temperature sensor fault unsigned int
Flag that shows if the communication with temperature & humidity sensor
is lost
0—1
0 = No
1 = Yes
6—9 Reserved, return 0
10 Relative humidity level unsigned int Actual relative humidity level 0—1.000 1.000 = 100,0 % rH
11 Output value 2 (rH) unsigned int Output value 2 (rH) 0—1.000
0 = 0 %
1.000 = 100 %
12 Relative humidity alert flag unsigned int
Flag indicates that measured Relative humidity is outside set alert
values. Set to '1' when the measured value is outside the Relative
humidity alert values defined by holding registers 21 and 22
0—1
0 = Relative humidity measurement OK
1 = Relative humidity measurement too
low/high
13 Relative humidity range limit flag unsigned int
Flag indicates that measured Relative humidity is outside set range limit
values. Set to '1' when the measured Relative humidity is outside limit
range values defined by holding registers 19 and 20
0—1
0 = Relative humidity range OK
1 = Relative humidity range too low/high
14 Humidity, temperature sensor fault unsigned int
Flag that shows if the communication with temperature & humidity
sensor is lost
0—1
0 = No
1 = Yes
15 Dew point level signed int Calculated dew point -700—700 200 = 20,0°C
16—20 Reserved, return 0

22 Output value 3 (CO
2
) unsigned int Output value 3 (CO
2
) 0—1.000
0 = 0 %
1.000 = 100 %
23 CO
2
alert flag unsigned int
Flag indicates that measured CO
2
level is outside set alert values. Set to
'1' when the measured value is outside the CO
2
values defined by holding
registers 25 and 26
0—1
0 = CO
2
measurement OK
1 = CO
2
measurement too low/high
24 CO
2
range limit flag unsigned int
Flag indicates that measured CO
2
is outside set range limit values. Set
to '1' when the measured CO
2
is outside limit range values set defined by
holding registers 23 and 24
0—1
0 = CO
2
range OK
1 = CO
2
range too low/high
25 CO
2
Sensor fault unsigned int Flag that shows if the communication with the CO
2
sensor is lost 0—1
