Line 2 Current Economizer Open Percentage
The Economizer is optional. This shows the Outdoor Air
Damper open percentage. If Economizer Control is not
configured it will display 0%.
Line 3 Current Wetbulb Temperature
The Outdoor Air Wetbulb Temperature is optional. To
display the Outdoor Air Wetbulb Temperature, an Outdoor
Air Temperature Sensor (or an Outdoor Air Temperature
Broadcast) and a Outdoor Air Relative Humidity Sensor
must be installed. If these conditions exist, this line will
display the calculated Outdoor Air Wetbulb Temperature. If
these conditions do not exist it will display 0°F.
Line 4 Current CO
2
Level
The CO
2
Level is optional. It requires a CO
2
Sensor be
installed and configured to display the CO

Line 2 Current Modulating Cooling Output Signal Percentage
Indicates the percentage of the output signal being supplied
to a Modulating Cooling device when you have configured
this option for your HVAC unit. If reverse acting is
configured, this percentage will be reversed. See the
following examples for clarification.
Standard Operation:
0-10 VDC 0% = 0 VDC 100% = 10 VDC
2-10 VDC 0% = 2 VDC 100% = 10 VDC
1.5-5.0 VDC 0% = 1.5 VDC 100% = 5.0 VDC
