VCM-X Conﬁ guration Screens

Conﬁ guration Screen #32 - CO

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

sensor signal output is

being provided. Enter <2> for a 0-10 VDC CO

sensor signal (standard

sensor used). Enter <1> for a 4-20 mA CO

sensor signal. Enter <0>

if no CO

sensor is used. Default is None.

Conﬁ guration Screen #33 - CO

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

Sensor

scaling for proper reading of the CO

Sensor output. The Standard CO

Sensor should be scaled to 2000 PPM. Enter <0> if no CO

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.
