*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.

Exhaust Fan

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

7

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.
