INSTALLATION

Remove security screw on bottom of Room

Controller cover.

Open unit by pulling on bottom side

of Room Controller (fig. 1).

Remove wiring terminals from

sticker.

Read FCC ID and IC label installed

in the 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 out 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 proper side of base is

up.

5. Install anchors in wall.

6. Insert screws in mounting holes

on each side of base (fig. 2).

7. Gently swing back 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).

3 | 028-0228-06 November 2015

11. Re-Install wiring terminals in correct locations (fig. 3).

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

wall.

13. Install security screw.

If 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 wrong 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 / installer / 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: Economizer output uses 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 level 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

actual status of the system.

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

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

Manual scroll 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 a 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.

The priority for the alarms is as follows:
