INSTALLATION

Remove the security screw on the bottom of the Fan Coil Terminal Equipment Controller cover.

 Open unit by pulling on the bottom

side of Fan Coil Terminal Equipment Controller (Fig. 1).

 Remove wiring terminals from

sticker.

 Please read the FCC ID and IC

label installed in the cover upon removal of cover for the wireless products.

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 an air discharge grill.

4. Should not be affected by direct sun radiation.

5. Nothing should restrict vertical air circulation to the Fan Coil Terminal Equipment Controller.

Installation

1. Swing open the Fan Coil Terminal Equipment Controller PCB to the left by pressing the PCB locking tabs (Fig. 2).

2. Pull out cables 6” out from the wall.

3. Wall surface must be flat and clean.

4. Insert cable in the central hole of the base.

5. Align the base and mark the location of the two mounting holes on the wall. Install proper side of base up.

6. Install anchors in the wall.

7. Insert screws in mounting holes on each side of the base (Fig. 2).

8. Gently swing back the circuit board on the base and push on it until the tabs lock it.

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

10. Insert each wire according to wiring diagram.

11. Gently push excess wiring back into hole (Fig. 3).

12. Re-Install wiring terminals in their correct locations (Fig. 3).

 If replacing an old Terminal Equipment Controller, label the wires

before removal of the old Terminal Equipment Controller.

 Electronic controls are static sensitive devices. Discharge yourself

properly before manipulation and installing the Terminal Equipment Controller.

 Short circuit or wrong wiring may permanently damage the Terminal

Equipment Controller or the equipment.

 Anti-short cycling can be set to 0 minutes for equipment that possess

their own anti cycling timer. Do not use that value unless the equipment is equipped with such internal timer. Failure to do so can damage the equipment. All VT7000 series Terminal Equipment Controllers are to be used only as operating controls. Whenever a control failure could lead to personal injury and/or loss of property, it becomes the responsibility of the user to add safety devices and/or alarm system to protect against such catastrophic failures.

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

14. Install security screw.

CONFIGURABLE BI/UI INPUTS OVERVIEW

Binary input #1 can be configured for the following 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-PIR- Guide-Exx. 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 PIR accessory covers

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

Binary input #2 can be configured for the following functions:

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

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 a PIR accessory cover 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 PIR accessory cover will be ignored. Use a Normally Closed contact switching device.

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.

4. (Filter): a backlit flashing Filter alarm will be displayed on the Terminal Equipment Controller LCD 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 backlit flashing Service alarm will be displayed on the Terminal Equipment Controller LCD 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 #3 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 system is setup as 2.0. Parameter ( Out1Conf ) set as 2.0.

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 system is setup as 2.0. Parameter ( Out1Conf ) set as 2.0.

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

4 | PIR Ready VT7300 Series-Installation Guide

Only used and valid if system is setup as 2.0. Parameter ( Out1Conf ) set as 2.0.

If temperature is > 77 °F = Hot air / water present If temperature is < 75 °F = Cold air / water present

5. (SS) Supply air sensor monitoring: Used for supply air temperature monitoring.

Only used for network reporting of the supply air temperature. Has no internal function in the Terminal Equipment Controller.
