Configurable parameters of the sensor regulator SCO2-IAQ
To access the parameters mode, in normal operating mode press MODE continuously (2s aprox) until the user menu appears on the
screen (date setting, time programming, identifier, parameters and reset). Using the UP and DOWN keys select torque and press MODE,
accessing the parameters mode at that moment (icon ).
Note: During parameter mode, the probe controller does not communicate through the serial communication channel.
In parameter mode the functions of the pushbuttons are as follows:
-
ON/OFF
: Exits parameter mode.
-
MODE
: Accepts the value of the displayed parameter and goes to the next parameter.
-
UP
: Increase the value of the parameter.
-
DOWN
: Decrease the value of the parameter..
Parameter list
1.
MINIMUM CONSIGNMENT CO2 (
output “Regulation CO2”) (range: 400ppm to1400ppm; by default: 400ppm) [Parameter 1
≤
Parameter 2]
2.
MAXIMUM CONSIGNMENT CO
2 (output “Regulation CO2”) (range: 400ppm to 1400ppm; by default: 1400ppm) [Parameter 1
≤
Parameter 2]
Note: Scientific publications indicate that the limit of 1000 ppm CO2 should not be exceeded. But even from
a concentration of 0.08% (800 ppm) of carbon dioxide, performance, concentration and well-being are
compromised. We therefore recommend setting the maximum CO2 value (Parameter Cxxx) no more than 800
ppm.From the point of view of use, the lower the Cxxx set value, the more frequent the system on / off cycle
will be.
3.
HYSTERESIS
(output “Regulation CO2” on/off) (range: 50ppm to 400ppm; by default, 200ppm)
4.
PROPORTIONAL BAND
(output “Regulation CO2” proportional) (range: 100ppm to 600ppm; by default: 400ppm)
5.
INTEGRATION TIME
(output “Regulation CO2” proportional) (range: 0s to 240s; by default: 120s)
=0: Proportional Control
≠
0: Proportional-integral Control
Note: Whenever parameter mode is accessed, the PI control calculations are initialized.
6.
MINIMUM PROPORTIONAL OUTPUT
(output “Regulation CO2” proportional) (range: 0% to 100%; by default: 0%) [Parameter 6
≤
Parameter 7]
7.
MAXIMUM OUTPUT PROPORTIONAL
(output “Regulation CO2” proportional) (range: 0% to 100%; by default: 100%) [Parameter 6
≤
Parameter 7]
8.
TIME BETWEEN ACQUISITION OF MEASURES
(CO2 measured filtering ) (range: 1 a 100; by default: 10).
To obtain the time between CO2 measurements, given in ms, multiply this parameter by 50. 1:
50ms … 10: 500ms(0,5s) … 100: 5000ms(5s)
9.
LIMITS ON CONSECUTIVE MEASURE
(CO2 measured filtering ) (range: 1 [±1] to 16 [±16]; by default: 1 [±1]).
10.
DISPLAY IN DIGITS PROPORTIONAL OUTPUT
(range: 0 to 1; by default: 1).
0: No visualization
1: With visualization
11.
ENABLE/DISABLE ALARM
(range: 0 to 2; by default: 0).
0: Alarm disabled.
1: Alarm enable with visualization on display al.
2: Alarm disabled with visualization in display al & with blink of the backlight.
12.
MINIMUM TIME FOR RENEWAL OPERATION PER HOUR
(range: 0min to 60min; by default: 10min) Output on/off
0min: Output off permanently as long as CO2 is correct.
>0min y <60min: Auto output depending on CO2 and timing.
60min: Output on permanently.
13.
OFFSET CO2
Measure (range: -250ppm to +250ppm; by default: 0ppm)
14.
COMMUNICATIONS DIRECTORATE
(range: 1 to 240; by default: 1)
