RNE Modular Controller Field Technical Guide

START-UP & COMMISSIONING

WARNING: Observe Polarity! All boards must be wired

with GND-to-GND and 24 VAC-to-24 VAC. Failure to ob-

serve polarity will result in damage to one or more of the

boards. Expansion modules must be wired in such a way that

the Expansion modules and the RNE Controller are always

powered together. Loss of power to the Expansion module

will cause it to become inoperative until power is restored

to the Expansion module.

Check all wiring leads at the terminal block for tightness. Be sure that

wire strands do not stick out and touch adjacent terminals. Conﬁ rm

that all sensors required for your system are mounted in the appropriate

location and wired into the correct terminals on the RNE Controller. Be

sure any expansion modules connected to the RNE Controller are also

correctly wired just as you did for the RNE Controller.

After all the above wiring checks are complete, apply power to the RNE

Controller and all expansion modules connected to it.

Initialization

On system power up, a 30-second startup delay is performed where all

default setpoints are initialized, LED’s are initialized, and all outputs

are turned off.

When power is ﬁ rst applied, LED1 and LED2 will ﬂ ash out the controller

address. LED1 will ﬂ ash to represent the tens position. LED2 will ﬂ ash

to represent the ones position. After the controller address is complete,

there will be a short pause and then 60 fast ﬂ ashes to represent controller

initialization. There will be no controller operation or communications

during initialization. After initialization, LED1 and LED2 will continu-

ously ﬂ ash the status code.

Example of a controller address of 59:

LED1 will ﬂ ash 5 times. LED2 will ﬂ ash 9 times.

See Table 3 on page 71 in the RNE Controller Troubleshooting section

of this manual for detailed diagnostic blink code information.

Operating Summary

There is a standard set of operating instructions that are continuously

repeated during normal operations. They are listed below.

1. Read Analog Inputs for Temperatures, Pressures, and

Binary Contact Closures.

2. Calculate Occupied/Unoccupied Mode of Operation.

3. Calculate HVAC Mode of Operation.

4. Set all outputs to match calculations for Heating or Cooling

or Vent Mode.

5. Broadcast information to other controllers if conﬁ gured.

6. Log all temperatures and output conditions.

7. Repeat steps 1 through 6 continuously.

Programming the Controller

The next step is programming the controller for your speciﬁ c require-

ments. In order to conﬁ gure and program the RNE Controller, you must

use an operator interface. Four different operator interfaces are avail-

able for programming and monitoring of the RNE Controller These are

depicted in Figure 39 and are as follows:

• Modular Service Tool SD and Modular System

Manager SD

• System Manager TS II

• Computer with Prism 2 Software Installed and

the CommLink 5 Communications Interface

Any of these devices or a combination of them can be used to access

the status, conﬁ guration, and setpoints of any controller on your com-

munications loop.

If using the Modular Service Tool SD, Modular System Manager SD, or

System Manager Touch Screen II with your system, refer to the VCM-X

/ RNE Controller Operator Interfaces SD Technical Guide or System

Manager TS II Technical Guide for programming instructions.

If using a computer and the Prism 2 Software, refer to the Prism 2

Technical Guide.

No matter which operator interface you use, we recommend that you

proceed with the programming and setup of the RNE Controller in the

order that follows:

1. Conﬁ gure the Controller for your application.

2. Program the Controller setpoints.

3. Program the Controller operation schedules.

4. Set the Controller current time and date.

5. Review Controller status screens to verify system

operation and correct Controller conﬁ guration.
