INPUTS & OUTPUTS

RNE Modular Controller Field Technical Guide

*BI4 - Remote Forced Occupied Mode Input*

When this wet contact input closes, it will force the RNE Controller

into the Occupied Mode. When the Remote Forced Occupied Signal is

removed, the controller will revert to the Unoccupied Mode of operation

if no internal or external schedule has been conﬁ gured or is in effect

when this occurs.

BI5 - Remote Forced Heating Mode Input

This wet contact input is used to provide a means for another BAS or

control device (by others) to force the unit into Heating Mode when it

closes. See the note regarding Remote Force Mode Setting that follows.

BI6 - Remote Forced Cooling Mode Input

This wet contact input is used to provide a means for another BAS or

control device (by others) to force the unit into Cooling Mode when it

closes. See the note regarding Remote Force Mode Setting that follows.

NOTE: Remote Forced Heating or Cooling Modes require that

you enter a value of 1 for both the Heating and the Cooling

Setpoints for the HVAC Mode Enable and the Mode Enable

Sensor must be set as Supply Air Temperature. The RNE

Controller will then look for wet contact closures on the

Remote Forced Cooling Mode and Remote Forced Heating

Mode inputs to enable the HVAC Modes. If both the Remote

Forced Heating and Remote Forced Cooling Modes are ac-

tive, the unit will operate in Vent Mode. The unit may also

be operated in Vent Mode by providing a wet contact closure

signal to the Remote Occupied Input.

BI7 - Exhaust Hood On Input

When this wet contact input closes, the RNE Controller switches from

Indoor Air Control to Outdoor Air Control. This is typically used on CAV

applications requiring MUA/CAV Dual Damper (Hood On/Off) Modes.

BI8 - Remote Forced Dehumidiﬁ cation

This wet contact input is used to provide a means for another BAS

or control device (by others) to force the RNE Controller into

Dehumidification Mode. You must set the Humidity Setpoint to

100% for the Remote Forced Dehumidiﬁ cation feature to function.

* 4 Binary Input Expansion Module

A 4 Binary Input Module can be used in lieu of using the VCM-X Ex-

pansion Module when only the ﬁ rst 4 Binary Inputs are required. You

can use the VCM-X Expansion Module or the 4 Binary Input Expansion

Module, but not both.

12-Relay Expansion Module

Please refer to the user-conﬁ gurable relays in Table 2 for relay deﬁ nitions.

Expansion Modules Inputs & Outputs

Table 2: User-Conﬁ gurable Relay Outputs

No. Relay Description Details

1 Heating Stages Conﬁ gure (1) Relay for each stage of heat. Conﬁ gure (1) Relay for Mod heat.

2 Cooling Stages Conﬁ gure (1) Relay for each stage of cooling. For chilled water, conﬁ gure (1) Relay for cooling.

3 Warm-Up Mode (VAV Boxes) Conﬁ gure (1) Relay for Warm-Up Mode when Non-Orion VAV/Zone Controllers are used.

4 Reversing Valve (Heat Pumps) Conﬁ gure (1) Relay for Reversing Valve operation. Can be conﬁ gured for heating or cooling.

5 Reheat Conﬁ gure (1) Relay for On/Off reheat when used.

6 Exhaust Fan Conﬁ gure (1) Relay for enabling exhaust fan when building pressure control is used.

Pre-Heater

(Low Ambient Protection)

Conﬁ gure (1) Relay for pre-heat coil when required. Activated when the outdoor air temperature drops

below the ambient protection setpoint.

8 Alarm Conﬁ gure (1) Relay to initiate an alarm output when any VCM-X alarm occurs.

9 Override Conﬁ gure (1) Relay to initiate an output signal when space temperature override button is pushed.

10 Occupied Conﬁ gure (1) Relay to initiate an output signal any time the VCM-X is in occupied mode.

11 OA Damper

Conﬁ gure (1) Relay to initiate an output signal when the OA damper moves beyond its minimum during

economizer operation, or when the OA damper opens in a MUA application, or when the damper opens

during Hood On operation.

12 Heat Wheel

Conﬁ gure (1) Relay that turns heat wheel on when in occupied operation and turns heat wheel off when

in economizer mode.

13 Emergency Heat

Conﬁ gure (1) Relay for ﬁ xed stage Emergency Heat in a heat pump unit. Not available on VCM-X WSHP

E-BUS controller.
