Register 8:
Time of integration (output “Regulation CO2” proportional) [read/write].
The value that is sent is the value of the integration time (0s a 240s) in binary 16 bits.
=0s: Control proportional.
≠
0s: Control proportional integral.
Value by default: 120 [120s: Control proportional integral].
CONTROL PROPORTIONAL-INTEGRAL (output proportional):
Control proportional: The equipment regulates the output proportional 0… 10V according to the graphs included in this document.
Control integral: In the event that during a time interval (integration time), the error (difference between consignment and air quality measurement)
remains constant or is not reduced, the equipment automatically increases the output 0… 10V, with the aim that the air quality measure reaches
the consignment established in the equipment.
Note
: In case any of Registers 7 or 8 is modified, the PI control calculations are initialized.
Register 9:
Minimum output proportional (output “Regulation CO2” proportional) [read/write].
The value that is sent is the value of the minimum output proportional (0% a 100%) in binary16 bits.
Value by default: 0 [0%]. [Register 9
≤
Register 10]
Register 10:
Maximum output proportional (output “Regulation CO2” proportional) [read/write].
The value that is sent is the value of the maximum output proportional (0% to 100%) in 16-bit binary.
Valore per difetto: 100 [100%]. [Registro 9 s; Registro 10]
Register 11: Filtrated measure of CO2 [read/write].
- Byte high: Time between acquisition of measurements.
The value that is sent is the filtering value (1 to 100) in 16-bit binary.
To obtain the time between CO2 measurements, given in ms, multiply this parameter by 50.
Value by default: 10 [500ms].

Byte low:
Consecutive measurement limits.
The value that is sent is the limit value (± 1 to ± 16) in 16-bit binary.
Value by default: 1 [±1].
Register 12
: Visualization in digits output proportional [read/write].
- 0: No Visualization.
- 1: With Visualization.
Value by default: 1 [With Visualization in digits output proportional].
Register 13:
Enable/disable alarm [read/write].
- 0: Alarm desabled.
- 1: Alarm enabled with Visualization in display al.
- 2: Alarm enabled with Visualization in display al y with blinking of backlight.
Value by default: 0 [Alarma deshabilitada].
Note:
With regulator in off, no alarm is indicated on the display.
Register 14:
Minimum hourly renewal operation timer (output “Regulation CO2” On/off) [read/write].
The value that is sent is the value of the timing (0min to 60min) in 16-bit binary.
Value by default: 10 [10min].
0min: Output off permanently if CO2 is correct.
>0min y <60min: Output auto as a function of CO2 and timer. 60min: Output on permanently.
Register 15:
Offset measure CO2 (measure calibration of CO2) [read/write].
Value by default: 0 [0ppm].
Negative values are sent in 2's complement in 16- bit binary.
-250 ppm
0xFF06 0 ppm 0x0000
