16. "Hum setpnt"
Default:
Range:
Increment:
40.0% RH
0.0 to 100.0% RH
0.1% RH
Set the desired humidity setpoint. The setpoint value is restricted by the minimum at Step 13, "Hum setpnt" and at Step 14, "Hum
setpnt" values. The humidity symbol is also displayed.
17. "Humdty Mode"
OFF
OFF, hUn, Auto, and dhUn
Select the humidity mode that you want to authorize to the user. To authorize all the available modes, select Auto (Automatic
Mode). The selection made at this step determines the options available on the Operation mode. The controller can be set in
Humidification or Dehumidification mode or both. When both are used, the controller will request a humidity demand until the
humidity setpoint is reached. If the humidity level increases to the dehumidify setpoint (should be higher than humidity setpoint), the
controller will request a dehumidify demand, which usually activates air conditioning. The humidity symbol is also displayed.
CO2 Setpoints and Modes
The CO2 configuration setpoints require a functioning humidity sensor installed. These setpoints appear only on the models with the
CO2 sensor. For more information on supported models, see 'Error! Reference source not found.on page 1.
18. "CO2 Offset"
Default:
Offset:
Increment:
600 ppm
± 250 ppm
1.0 ppm
Compare the displayed CO2 level reading with a known value from a CO2sensing device. To offset or calibrate the sensor, use
the arrow buttons to set the desired CO2level reading. This is useful for controllers installed in areas where the CO2level is slightly
different than the prescribed value. The alarm icon appears in case of a sensor malfunction.
19. "CO2 Setpnt Min "
Default:
Range:
Increment:
400.0 ppm
0 to 1500.0 ppm
1.0 ppm
In the Operation mode, you cannot decrease the setpoint to less than the value set as the minimum CO2 setpoint. The minimum
value is restricted by the maximum value set at Step 19, "CO2 Setpnt". In other words, the value that is set as the minimum cannot
be greater than the maximum value. The CO2 symbol is also displayed.
20. "CO2 Setpnt Max "
Default:
Range:
Increment:
1500 ppm
0 to 2000 ppm
1.0 ppm
In the Operation mode, you cannot increase the setpoint to more than the value set as the maximum CO2 setpoint. The maximum
value is restricted by the minimum value set at Step 18, "CO2 Setpnt".In other words, the value that is set as the maximum cannot
be less than the minimum value. The CO2 symbol is also displayed.
21. "CO2 Setpnt"
Default:
Range:
Increment:
600.0 ppm
400 to 1500.0 ppm
1.0 ppm
Set the desired limit of the CO2concentration. The setpoint value is restricted by the maximum range at Step 19, "CO2 Setpnt".
The CO2 symbol is also displayed.
