RNE CONFIGURATION
33
RNE Confi guration Screens
Confi guration Screen #27 - Monitor Return Air
CFM
RNE Cnfg ID 101
Monitor Return
Air CFM: NO
[0=NO 1=YES]
Enter
<1>
for YES if you have an airfl ow monitoring station measuring
the CFM of the return airfl ow stream of this unit. Enter <0> for NO.
Default is NO.
Confi guration Screen #28 - Return Duct/
Damper Size
RNE Cnfg ID 101
Return Duct/Damper
Size: 0.00
[Area in sq. ft.]
For the Controller to properly calculate the return air CFM, you need to
enter the area in square feet of the return air duct/damper. When measur-
ing the return air damper area, be sure to measure the inside dimensions
of the damper. The more accurate the measurements, the more accurate
the CFM reading will be. This value needs to be accurate to 2 decimal
places. Default is 0.00.
Confi guration Screen #29 - Monitor Supply Air
CFM
RNE Cnfg ID 101
Monitor Supply
Air CFM: NO
[0=NO 1=YES]
Enter
<1>
for YES if you have an airfl ow monitoring station measuring
the CFM of the supply airfl ow stream of this unit. Enter
<0>
for NO.
Default is NO.
Confi guration Screen #30 - Supply Duct/
Damper Size
RNE Cnfg ID 101
Supply Duct/Damper
Size: 0.00
[Area in sq. ft.]
For the Controller to properly calculate the supply air CFM, you need
to enter the area in square feet of the supply air duct/damper. When
measuring the supply duct damper area, be sure to measure the inside
dimensions of the damper. The more accurate the measurements, the
more accurate the CFM reading will be. This value needs to be accurate
to 2 decimal places. Default is 0.00.
Confi guration Screen #31 - CO
2
Sensor
Output Signal
RNE Cnfg ID 101
CO2 Sensor
Output Signal: 0
[0=None 1=mA 2=VDC]
The RNE needs to know what type of CO
2
sensor signal output is being
provided. Enter
<2>
for a 0-10 VDC CO
2
sensor signal (standard sensor
used). Enter
<1>
for a 4-20 mA CO
2
sensor signal. Enter
<0>
if no CO
2
sensor is used. Default is None.
Confi guration Screen #32 - CO
2
Sensor
Maximum Scale
RNE Cnfg ID 101
CO2 Sensor Maximum
Scale: 2000 PPM
Enter 0 If No Sensor
Default is 2000 PPM. The RNE needs to know the CO
2
Sensor scaling
for proper reading of the CO
2
Sensor output. The Standard CO
2
Sensor
should be scaled to 2000 PPM. Enter <0> if no CO
2
sensor is used.
Default is 2000.
