2 Output value 1 (T) unsigned int Output value 1 (T) 0—1.000 0 = 0 %
1.000 = 100 %
3Temperature alert ag unsigned int
Flag indicates that measured Temperature is outside set alert values.
Set to '1' when the measured value is outside the Temperature alert
values dened by holding registers 13 and 14
0—1
0 = Temperature measurement OK
1 = Temperature measurement too low/
high
4 Temperature range limit ag unsigned int
Flag indicates that measured temperature is outside set range limit
values. Set to '1' when the measured temperature is outside limit range
values dened by holding registers 11 and 12
0—1 0 = Temperature range OK
1 = Temperature range too low/high
5Humidity, 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 ag 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 dened 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 ag 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 dened 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
21 CO2 level unsigned int Actual CO2 level 0—2.000 2.000 = 2.000 ppm
22 Output value 3 (CO2)unsigned int Output value 3 (CO2)0—1.000 0 = 0 %
1.000 = 100 %
23 CO2 alert ag unsigned int
Flag indicates that measured CO2 level is outside set alert values. Set to
'1' when the measured value is outside the CO2 values dene d by holding
registers 25 and 26
0—1 0 = CO2 measurement OK
1 = CO2 measurement too low/high
24 CO2 range limit ag unsigned int
Flag indicates that measured CO2 is outside set range limit values. Set
to '1' when the measured CO2 is outside limit range values set dened by
holding registers 23 and 24
0—1 0 = CO2 range OK
1 = CO2 range too low/high
25 CO2 Sensor fault unsigned int Flag that shows if the communication with the CO2 sensor is lost 0—1 0 = No
1 = Yes
26—50 Reserved, return 0
