INSTALLATION

Preparation

• Remove the security screw (if any) on the bottom of the Terminal Equipment Controller cover.

• Open unit by pulling on bottom side of the Terminal Equipment Controller (Fig. 1).

• Read FCC ID and IC label installed in cover before installing any wireless product.

• Ensure correct side of base faces up.

Location

1. Do not install on outside wall.

2. Do not install in areas with direct heat source.

3. Do no install near any air discharge grill.

4. Do not install in areas exposed to direct sunlight.

5. Ensure Controller has sufﬁcient air circulation.

6. Ensure wall surface is ﬂat and clean.

Installation

1. Pull cables 15 cm ( 6” ) out from wall.

2. Align base and mark location of two mounting holes on wall.

3. Install anchors in wall.

4. Insert cable in central hole of base.

5. Insert screws in mounting holes on each side of base.

6. Strip each wire 1/4” ( 0.6 cm) from end.

7. Insert each wire and screw according to wiring chart.

8. Gently push excess wiring back into hole.

9. Gently align cover to top of base and snap in place from bottom.

10. Install security screw.

• If replacing an existing Line Voltage FCU Controller, label wires before removal of Controller.

• Electronic controls are static sensitive devices. Discharge yourself correctly before manipulating and installing Controller.

• A short circuit or wrong wiring may permanently damage Controller or equipment.

• All VT8300 ® series controls are designed for use as operating controls only and are not safety devices. Tampering with the devices or unintended application of the devices will result in a void of warranty.

• This device must be installed to provide a separation distance of at least 8in (40cm) from all persons and must not be collocated or operating in conjunction with any other antenna

CONFIGURABLE BI/UI UNIVERSAL INPUTS OVERVIEW

Universal input #16 can be conﬁgured for the following binary functions:

1. (None): No function will be associated with the input

2. (Rem NSB): remote NSB timer clock input. The scheduling will now be

set as per the binary input. It provides low cost setback operation via a dry contact.

Contact opened = Occupied

Contact closed = Unoccupied

3. (Motion NO) and (Motion NC): Advanced PIR occupancy functions using

a normally open (NO) or normally closed (NC) remote PIR motion sensor. Occupancy mode is now set as per applied PIR function and conﬁguration. Application information and examples are available on document: APP-PIRSE8xxx. This document will provide the installers and system designers with detailed examples on applications, parameter conﬁguration information, sequence of operation, troubleshooting and diagnostic help required for the proper usage of the onboard PIR sensor.

4. (Window) EMS: Forces the system to disable any current heating or cooling

action by the Terminal Equipment Controller. The mode stays the same and the current setpoints are the same occupied setpoints. Only the outputs are disabled. There is a Door/Window alarm displayed on the Terminal Equipment Controller to indicate to the local tenant that the door/window needs to be closed for cooling or heating to resume. Use NC contact.

Contact opened = System disabled with local Window alarm

Contact closed = System enabled

Universal input #17 can be conﬁgured for the following binary functions:

1. (None): No function will be associated with the input

2. (Door Dry) Door contact & Motion detector: This conﬁguration is only

functional if binary input #1 is set to Motion NO or Motion NC or an onboard PIR sensor is used. With this sequence enabled, the occupancy is now dictated through those 2 inputs. Any motion detected will set the zone to occupied status. The zone will remain permanently in occupied mode until the door contact switch opens momentarily. The Terminal Equipment Controller will then go in stand-by mode. If more movements are detected, the occupied mode will resume. While the door is opened, any movements detected by the remote PIR sensor or the onboard PIR sensor will be ignored. Use a Normally Closed contact switching device.

4. (Filter): a Filter alarm short text message will be

displayed on the Terminal Equipment Controller screen when the input is energized. It can be tied to a differential pressure switch that monitor ﬁlters

Contact opened = No alarm

Contact closed = Alarm displayed

5. (Service): a Service alarm short text message

will be displayed on the Terminal Equipment Controller screen when the input is energized. It can be tied in to the AC unit control card, which provides an alarm in case of malfunction.

Contact opened = No alarm

Contact closed = Alarm displayed

Universal input #19 can be conﬁgured for the following functions:

1. (None): No function will be associated with the

input

2. (COC/NH) Change over dry contact. Normally Heat: Used for hot / cold air / water

change over switching in 2 pipe systems.

Contact closed = Cold air/water present

Contact opened = Hot air/water present

Only used and valid if Room Controller is set up for a 2 pipe system.

3. (COC/NC) Change over dry contact. Normally Cool: Used for hot / cold air / water

change over switching in 2 pipe systems.

Contact closed = Hot air/water present

Contact opened = Cold air/water present

Only used and valid if Room Controller is set up for a 2 pipe system.

4. (COS) Change over analog sensor: Used for hot / cold air / water change over switching in 2 pipe systems.

Contact opened = Door opened

Contact closed = Door closed

3. (RemOVR): temporary occupancy remote override contact. This function

disables the central button override function on the Terminal Equipment Controller. The override function is now controlled by a manual remote momentarily closed contact. When conﬁgured in this mode, the input operates in a toggle mode. It is now possible to toggle between unoccupied & occupied setpoints for the amount of time set by parameter (TOccTime) temporary occupancy time.

028-0429-02 www.viconics.com | sales @viconics.com February 2015

Only used and valid if Room Controller is set up for a 2 pipe system.

If temperature is > 77 °F = Hot air / water present

If temperature is < 75 °F = Cold air / water present

APPENDIX A: TERMINAL CORRESPONDANCE

The terminals of a VT8300 are identiﬁed differently and have a wider range of possible functions compared to those of any of the VT7000 series Room Controllers. Nonetheless, there is a direct correspondance of functions between the terminals of the VT7000 series and the VT8300 series. Consult the table below to verify the appropriate terminal when replacing a VT7000 Room Controller with a VT8300 Room Controller.

APPENDIX B: POWER OUTAGE CLOCK RESET

In the event of a power outage, VT8300 Room Controllers retain the correct time as long as the duration of the power outage is not prolonged. Depending on the duration of the power outage, the Room Controllers internal clock may need to be updated or reset completely. The following table gives an indication of the expected clock performance after a power outage of a given duration.

Outage duration Room Controller behaviour

0 - 24 hours Clock functions are normal

24 - 36 hours Clock accuracy not guaranteed, time may need to be adjusted

36 - 72 hours Clock no longer increments and will need to be adjusted when power is

restored.

72+ hours Clock functions are fully reset, and will need to be reinitialized as per a

new installation.
