VCM-X Confi guration Screens
Confi guration Screen #32 - CO
2
Sensor
Output Signal
VCM-X Cnfg ID 59
CO2 Sensor
Output Signal: 0
[0=None 1=mA 2=VDC]
The VCM-X 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 #33 - CO
2
Sensor
Maximum Scale
VCM-X Cnfg ID 59
CO2 Sensor Maximum
Scale: 2000 PPM
Enter 0 If No Sensor
Default is 2000 PPM. The VCM-X 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.
Confi guration Screen #34 - Building Pressure
Modulating Control
VCM-X Cnfg ID 59
Building Pressure
Mod Control: NO
[0=NO 1=YES]
Enter <1> for YES if Modulating Building Pressure Control is needed.
Modulating Building Pressure Control is used for a VFD Exhaust Fan or
a Modulating Exhaust Fan Damper Actuator for Direct Acting Building
Pressure Control. Modulating Building Pressure Control is also used for
a modulating outdoor air damper actuator for Reverse Acting Building
Pressure Control. Enter
<0>
for NO if Modulating Building Pressure
Control is not needed when using a Constant Volume Exhaust Fan for
On/Off Control. Default is NO.
Confi guration Screen #35 - Building Pressure
Reverse Acting
VCM-X Cnfg ID 59
Building Pressure
Rev Acting: NO
[0=NO 1=YES]
Enter
<1>
for YES if Reverse Acting Building Pressure control is
needed. Reverse Acting Building Pressure Control can either be On/
Off or Modulating Control. Modulating Control is normally used for
this confi guration. On a drop in Building Pressure, below the Building
Static Pressure Setpoint, the Outdoor Air Damper will modulate open
to increase pressure. Enter
<0>
for NO. Default is NO.
Confi guration Screen #36 - Building Pressure
Output Signal
VCM-X Cnfg ID 59
Building Pressure
Output Signal: 0
[0=0-10V 1=2-10V]
This Screen is used to confi gure the Building Pressure Output Signal
voltage needed for your application. You can select either a 0-10 VDC
signal (default) or enter
<1> to make the output signal 2-10 VDC as
required by the device you are using to control the pressure. Enter <0>
for 0-10 VDC. Default is 0.
Confi guration Screen #37 - Heat Pump Control
VCM-X Cnfg ID 59
Heat Pump
Control: NO
[0=NO 1=YES]
Enter <1> for YES if the HVAC unit is a Heat Pump. Enter <0> for
NO. Default is NO.
Confi guration Screen #38 - Reversing Valve
Active During Heat/Cool
VCM-X Cnfg ID 59
Rev. Valve Active
For: Cool
[0=Heat 1=Cool]
Enter <0> for Heat if your Heat Pump unit activates its Reversing Valve
during Heating operation. Enter
<1>
for Cool if your Heat Pump unit
activates its Reversing Valve during Cooling operation. Default is Heat.
