VCM-X / RNE Operator Interfaces Technical Guide

VCM-X CONFIGURATION

Conﬁ guration Screens

In order to correctly set up the VCM-X Controller, you must ﬁ rst con-

ﬁ gure several parameters in regard to the type of HVAC unit and system

you have installed. Most of these values and operating parameters are

only set once at the initial system setup and are never changed.

System Manager Instructions

No matter what screen or menu you’re in, press <SETPOINTS>. The

Unit Selection Screen will appear, requesting that you enter the unit ID

number. Enter the correct unit ID number of the VCM-X Controller

you want to conﬁ gure and press

<ENTER>. You will see the screen

shown below.

1) Change Setpoint

2) Configure Unit

3) Damper Force

ESC) Exit Menu

Press <2> to enter Conﬁ guration Screen #1.

Modular Service Tool Instructions

No matter what screen or menu you’re in, press <CONFIGURATION>.

The Unit Selection Screen will appear, requesting that you enter the unit

ID number. Enter the correct unit ID number of the VCM-X Controller

you want to conﬁ gure and press

<ENTER>. You will then see Unit

Conﬁ guration Screen #1.

Conﬁ guration Screen #1 - Duct Static

Pressure

VCM-X Cnfg ID 59

Duct Static Pressure

Control: YES

[0=NO 1=YES]

If the HVAC unit has a Supply Fan that delivers a Constant Volume of

air, enter <0> for NO. If the HVAC unit has a Supply Fan that delivers

a Variable Volume of Air using a VFD or a Bypass Damper, enter <1>

for YES. Default is YES.

Conﬁ guration Screen #2 - Supply Fan Cycle

VCM-X Cnfg ID 59

Supply Fan Cycle

Mode: NO

[0=NO 1=YES]

If you want the HVAC unit’s Supply Fan to run during Heating, Cool-

ing, or Dehumidiﬁ cation Modes, enter

<1> for YES. If you want the

HVAC unit’s Supply Fan to run continuously while in the Occupied

Mode, regardless of the Heating, Cooling, or Dehumidiﬁ cation Modes,

enter <0> for NO. Default is NO.

Conﬁ guration Screen #3 - HVAC Mode Enable

VCM-X Cnfg ID 59

HVAC Mode Enable

Supply Air

Press “0” to Change

Enter <0> to select the Temperature Sensor that will determine the

Heating, Cooling, or Vent Mode of operation. The selections are:

 Supply Air

This is typical for VAV applications. Occupied Cooling

with Morning Warm-up.

 Outdoor Air

This is for 100% Outdoor Air (MUA) units.

Dehumidiﬁ cation utilizes a Dewpoint Calculation if

equipped with an Outdoor Air Humidity Sensor.

 Space Temperature

This is for any unit that conditions a space and is not 100%

Outdoor air. Occupied/Unoccupied Heating, Cooling, and

Vent Modes of operation.

 Return Air

This selection can be used when an Average Building

Temperature (the Return Air Temperature) needs to

determine Heating, Cooling, and Vent Modes of operation.

 Supply Air/Tempering

This selection is for VAV “cooling only” applications where

because of cold outdoor temperatures, even at minimum

damper position, you may need to enable heat to maintain

the cooling near its Cooling Supply Air Setpoint. When

heat is enabled during this sequence, it will control to

a non-adjustable setpoint that is 2ºF less than the Cooling

Supply Air Setpoint. Includes a Morning Warm-up

sequence.

Conﬁ guration Screen #4 - HVAC Reset Source

VCM-X Cnfg ID 59

HVAC Reset Source

No Reset

Press “0” to Change

The Supply Air Heating and Cooling Temperature Setpoints can be reset

using various input sources. Default is No Reset. Enter <0> to change/

select the desired Reset Source for Supply Air Temperature Reset. The

Single Zone VAV option should be selected in applications where the

Supply Fan VFD speed is reset based on the Space Temperature. If you

select No Reset, then neither the Supply Air Setpoint nor the Supply

Fan VFD Reset will occur. The selections are:

 No Reset  Fan VFD Percentage

 Space Sensor  Outdoor Sensor

 Return Air Sensor  Single Zone (SZ) VAV

 Remote Reset Signal  SZ VAV with CV Heating
