Data type
Description
Data
Values
1
Temperature reading
signed int
Actual temperature level
-300—700
500 = 50,0°C
2
Output value 1
unsigned int
Output value 1
0—1.000
0 = 0 %
1.000 = 100 %
3
Temperature alert flag
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 defined by holding registers 13 and 14
0—1
0 = Temperature measurement OK
1 = Temperature measurement too low/high
4
Temperature range limit
flag
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 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
Reserved, returns 0.
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.
21
CO2 level
unsigned int
Actual CO2 level
0—2.000
2.000 = 2.000 ppm
22
Reserved, returns 0
23
CO2 alert flag
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 defined by
holding registers 25 and 26
0—1
0 = CO2 measurement OK
1 = CO2 measurement too low/high
24
CO2 range limit flag
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 defined 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—40
Reserved, returns 0
41
Ambient light intensity
unsigned int
Measured ambient light intensity
0—32.000
1.000 = 1.000 lux
42
Active / Standby
unsigned int
Active or Standby indication according the
Active / Standby light level defined by holding
registers 35 and 36. If the measured light level
is between the two levels the indication is 0 (Low
light intensity)
0—2
0 = Low light intensity
1 = Active
2 = Standby
43
Ambient light sensor fault
unsigned int
Flag that shows if the communication with the
ambient light sensor is lost
0—1
0 = No
1 = Yes
