than the minimum temperature setpoint� The default temperature is 86°F (30°C)�
The minimum temperature setpoint is changed in the same manner� The minimum
value in the range can be any temperature between 32 and 122°F (0-50°C)� It must
be lower than the maximum temperature setpoint� The default setting is 50°F
(10°C)�
These two screens are visible only on models with the optional temperature sensor
and fieldbus outputs� Both screens will by greyed out until the level 2 password is
entered�
These parameters affect the Configure > Configure Setpoints > Set Temp Setpoint
and the Temperature Adjust screens�

The Set CO2 Full Scale screen is visible only on models with the CO
sensor� Two
2
settings are available, 2000 or 5000 ppm� Setting the CO
full scale allows the CO
2
2
value to be displayed on the vertical "thermometer" bar� It also affects the analog
output� This setting does not affect the numeric gas concentration display or the
fieldbus outputs� Thus in an environment that contains 3000 ppm of CO
, this
2
setting determines whether the vertical "thermometer" bar shows 100% full or 60%
full� It also determines whether the analog output contains 20 mA/10 V or 13�6 mA
/ 6�8 V� It does not affect the numeric display; it will show 3000 ppm� It does not
affect BACnet or Modbus, either; these will report 3000 ppm�
The default setting is 2000 ppm�
Configure menu > Configure Outputs > Set mA Ch2 Function
The IAQPoint monitor has three channels� Channels 1 and 2 report gas values�
Channel 2 can be configured to measure temperature (voltage) instead� Channel 3
measures humidity when the optional rH sensor is installed� Report Temperature
is the default when the monitor is configured with a temperature/humidity sensor,
otherwise Report Gas Conc� is the default�
The operation of the middle of the three analog outputs is determined at this
screen� (It will not be visible on digital models�) Models without the optional
temperature sensor route the gas signal to channel 2 by default and so do not
show this screen� Thus this screen is visible only on models with analog output and
a temperature sensor�
