PGD Features, Display and Interface Buttons

Backlit Display
The controller includes a large 132 x 64 pixel graphic backlit display with an intuitive menu system for settings, zone conditions, and alarms.

Illuminated Interface Buttons (Keys)
A six-button interface allows for easy setup and menu selection.

Unit Operation Information
The PGD display provides the following information:

• RAT: Return air sensor or room temperature
• SAT: Supply air temperature
• Blo: Blower operation percentage
• Fan: Outdoor fan percentage
• Unit Status: Current unit operation
• OAT: Outdoor air temperature
• OAH: Outdoor air humidity
• MAT: Mixed air temperature
• Dmp: Cooling or heating demand percentage

Unit Setup and Diagnostics
Unit setup features and diagnostics are accessible via the Menu Key. Consult the unit manual for detailed instructions.

Time and Date
The display shows the time and date in a configurable month/day/year format, including daylight savings time. Time and date stamps are used for alarm logging.

Setpoints, Additional Information and Alarm Logs
Heating and cooling setpoints can be configured using the PGD. Unit model and serial number are viewable. Alarm logs can also be displayed.

Interface Button Functions:

• Alarm Key: Allows viewing of active alarms, silences audible alarms, and resets active alarms.
• Menu Key: Allows entry to the Main Menu.
• Escape Key: Returns to the previous menu level or cancels a changed entry.
• Up Key: Steps to the next screen in the display menu or increases the value of a modifiable field.
• Enter Key: Accepts the current value of a modifiable field or advances the cursor.
• Down Key: Steps back to a previous screen in the display menu or decreases the value of a modifiable field.

[Image Description: A screenshot of the PGD display shows the date and time (10/25/18 Thu 22:48 U1), followed by various operational parameters: RAT 76.5F, OAT 52.7F, SAT 73.3°F, OAH 44.8%, Blo: 0%, MAT 66.6%, Fan: 0%, DMP: [empty]. Below these is 'Unit status:'. Another screenshot shows similar parameters and indicates navigation arrows (Up, Down) and buttons (Alarm, Menu, Escape, Enter).]

General

The PGD display kit enables BARD PLC family wall-mount units (MULTI-TEC, FUSION-TEC WR Series, and MEGA-TEC) to operate in an "orphan mode" with a dedicated display. Connecting the PGD allows access to unit setup, status, operation, and alarm displays from within the climate-controlled area.

The PGD replaces the TEC-EYE™ hand-held tool, offering identical permanently mounted functionality. Refer to the wall-mount unit installation and service manual for specific setup requirements. Information in unit manuals regarding TEC-EYE operation applies to the PGD display.

Note: PGD display kits do not support indoor humidity control and cannot be used with electric or mechanical reheat dehumidification.

Available Kits:

• 8620-306 Kit: Includes PGD, enclosure, 25' cable (with J10 connectors on each end), and instructions.
• 8620-307 Kit: Includes all items from the 8620-306 kit plus a remote temperature sensor. The existing return air sensor is replaced by this remote sensor for room temperature monitoring.

Mounting the PGD Enclosure

The PGD enclosure features four mounting holes for wall installation. The polycarbonate construction allows for easy drilling of additional holes if needed. The enclosure can also be mounted on a 2 x 4 handi box for conduit applications.

Before mounting, an opening must be made in the back of the enclosure to accommodate the 25' cable with J10 connectors.

PGD Connection to Unit

A 25' cable with J10 connectors is supplied. Connect one end to the back of the PGD display and the other to the unit's PLC board. 25' is the maximum recommended cable length. The cable can be shortened if proper J10 crimping tools are used.

Operation

Once installed and connected, and with AC breakers turned on, the unit is ready for standard heating and cooling mode (heating is optional).

Note: Balanced Climate™ and dehumidification features are not available with the PGD kit.

Available Features (in "orphan mode"):

• Emergency Cooling (economizer required)
• Alarm Logging
• Free Cooling
• Optimized Cooling (economizer required)
• Self Test
• Unit Disable

The PGD Kit allows remote viewing of status and programming of options. The fan will run continuously with this kit, using the return air sensor for temperature sensing.

8620-307 Kit Only

The 8620-307 kit includes a remote temperature sensor for placement away from the unit. The existing return air sensor is disconnected, and the remote sensor is connected to allow space temperature monitoring. Continuous fan operation is currently standard; a future software update will enable disabling this feature.

Remote Temperature Sensor Connection to Unit (8620-307 Kit Only)

To connect the remote temperature sensor, remove the existing return air sensor conductors and replace them with conductors from the remote sensor. Connection locations vary by unit model. Refer to Table 1 and Figures 4A, 4B, 5, 6A, and 6B on pages 5 and 6.

Field-supplied wire (18 to 22 gauge copper conductor) no longer than 35' is required for the remote temperature sensor connection.
