INSTALLATION

1. Remove security screw on bottom of

Room Controller cover.

2. Open unit by pulling on bottom side of

Room Controller (fig. 1).

3. Remove wiring terminals from sticker.

4. Read FCC ID and IC label installed in

cover.

Location

1. Should not be installed on an outside

wall.

2. Must be installed away from any

direct heat source.

3. Should not be installed near air

discharge grill.

4. Should not be affected by direct sun

radiation.

5. Nothing should restrict vertical air

circulation to Room Controller.

Installation

1. Swing open Room Controller PCB to

left by pressing PCB locking tabs (fig.

2).

2. Pull cables 6” out from wall. Ensure

wall surface is flat and clean.

3. Insert cable in central hole of base.

4. Align base and mark location of two

mounting holes on wall ensuring base

is in proper orientation. Arrow on

base should be facing up.

5. Install anchors in wall.

6. Insert screws in mounting holes on

each side of base (fig. 2).

7. Gently swing back the circuit board

on base and push until tabs lock.

8. Strip each wire 1/4 inch from end.

9. Insert each wire according to wiring

diagram.

10. Gently push excess wiring back into

hole (fig. 3).

11. Re-Install wiring terminals in correct

locations (fig. 3).

3 | 028-0377-03 November 2015

12. Re-install cover (top side first) and gently push extra wire length back into

hole in wall.

13. Install security screw.



When replacing an existing Room Controller, label the wires before

removal of the Room Controller.



Electronic controls are static sensitive devices. Discharge yourself

properly before manipulating and installing the Room Controller.



A short circuit or improper wiring may permanently damage the Room

Controller or the equipment.



All VT7000 series Room Controllers are designed for use as operating

controls only and are not safety devices. These instruments have

undergone rigorous tests and verification prior to shipping to ensure

proper and reliable operation in the field. Whenever a control failure

could lead to personal injury and or loss of property, it becomes the

responsibility of the user or installer or electrical system designer to

incorporate safety devices (such as relays, flow switch, thermal

protections, etc…) and or an alarm system to protect the entire system

against such catastrophic failures. Tampering with the devices or

unintended application of the devices will result in a void of warranty.

Main outputs wiring

Wiring notes:

Note 1: If the same power source is used for the heating stages, install jumper across

RC & RH. Maximum current is 2.0 amps.

Note 2: If auxiliary output is used to toggle occupancy of the electronic control card

inside the equipment, configure the relay parameter (Aux cont) to the N.O.

setting. A second relay can be added for additional functionality of the

occupancy output.

Note 3: The analog outputs and inputs use a half bridge rectifier. Reference of the

control signal is the common of the power supply of the Room Controller.

(Terminal C)

Note 4: Electromechanical contacts are to be used with the digital inputs. Electronic

triacs cannot be used as mean of switching for the input. The switched leg to

the input for the input to activate is terminal C (common)

Note 5: The transformer of the unit provides power to the t Room Controller and the

additional loads that will be wired to the Room Controller.

CONFIGURING AND STATUS DISPLAY INSTRUCTIONS

Status display

The Room Controller features a two-line, eight-character display. There is a low level

backlight that is always active and can only be seen at night.

When left unattended, the Room Controller has an auto scrolling display that shows the

current status of the system.

Each item is scrolled sequentially with the back lighting in low level mode. Pressing any key

will cause the back light to come on to high level.

Manual scrolling of each menu item is achieved by pressing the Yes (scroll) key repetitively.

The last item viewed will be shown on the display for 30 seconds before returning to

automatic scrolling. Temperature is automatically updated when scrolling is held.

Outdoor air temperature

Outdoor air temperature display is only enabled when outdoor air temperature sensor is

connected.

•A maximum range status display of 50 °C (122 °F) indicates a shorted sensor.

Associated functions, such as mode lockouts and economizer function are

automatically disabled.

•A minimum range status -40 °C (-40 °F) is not displayed and indicates an opened

sensor or a sensor not connected. Associated functions, such as mode lockouts

and economizer function are automatically disabled.

Alarms

•If alarms are detected, they will automatically be displayed at the end of the

status display scroll.

•During an alarm message display, the back lit screen will light up at the same

time as the message and shut off during the rest of the status display.

•Two alarms maximum can appear at any given time.

10 | 028-0377-03 November 2015

•The priority for the alarms is as follows:

Frost ON

Indicates that the heating is energized by the low limit frost protection room

temperature setpoint 5.6 °C (42 °F)

SetClock

Indicates that the clock needs to be reset. There has been a power failure

which has lasted longer than 6 hours

Service

Indicates that there is a service alarm as per one of the configurable digital

input (DI1 or DI2)

Filter

Indicates that the filters are dirty as per one of the configurable digital input

(DI1 or DI2)

Fan lock

Indicates that the heating and cooling action are locked out due to a defective

fan operation

DAS

Alarm

Indicates that the discharge air temperature is either too low or too high.

When any of the fan is ON, the FAN LED will illuminate

When heating is ON, the HEAT LED will illuminate

When cooling is ON, the COOL LED will illuminate
