Understanding the Local LCD
After applying power to a Rooftop Unit (RTU), a start-up countdown begins on the Unit Control Board (UCB) LCD. The screen will be blank if no faults are present. Navigation through menus is done using a joystick and two push buttons (ENTER, CANCEL, JOY).
Figure: Joystick and Push Buttons on UCB
The UCB features an LCD screen with three buttons below it: ENTER (left), CANCEL (right), and a central joystick labeled JOY. The joystick allows up, down, left, and right movements. Up and down movements of the joystick move the cursor (>) and scroll through selections in the active menu section.
Figure: UCB Top Level Menu
The top-level menu on the UCB LCD displays options such as: >Status, Alarms, Summary, Commission, Controller, Update, Details, Self Test, View Results. Each selection can lead to a sub-menu or display a property. Pressing "ENTER" displays sub-menu items or property values. The joystick is used to navigate between values.
IMPORTANT: Unit control boards with part numbers SE-SPU1001-5, SE-SPU1011-5, SE-SPU1002-5, SE-SPU1012-5 have different hardware components. These new components do not allow downgrading to firmware older than 3.3.1.186. An attempt to install an older version will display a message [Info 1025].
Example LCD Messages: FWU:OK Info 102, FWU:OK Info 1025.
Powering the Unit
Upon power application, the UCB initiates a start-up sequence. The LCD scrolls "Johnson Controls" and "JCI".
Figure: Powering the Unit Display
The LCD shows "Johnson" on the top line and "JCI" on the bottom line, with ENTER, CANCEL, and JOY buttons below. The display backlight and green Power LED remain lit. The red Fault LED flashes during start-up. During this sequence, the joystick and buttons are not functional.
After approximately 15 seconds, the green SA Bus LED either lights (UCB awaiting communication) or flashes (UCB established communication). The start-up sequence finishes in 90-120 seconds, displaying the current operating status (e.g., Idle, startup delay, cooling). The red Fault LED turns off, and the joystick and buttons become operational.
Figure: Start-up Countdown Display
The LCD shows a countdown (e.g., "18 Startup*") on the top line, with ENTER, CANCEL, JOY, and C PWR indicators below.
Commissioning with the Local LCD
The Commissioning view includes main menus and sub-menus. Your equipment configuration determines which menus appear.
Figure: Commissioning View: Second Level Menus
The LCD displays options like: >Standard, Options, Network Setup. Use the joystick to move between options and "ENTER" to select.
Validating Your Configuration
Use the Details > Service menu to ensure configuration parameters are correct. This view shows input values for sensors and coil sensors. If no value appears, the input states "No Input".
IMPORTANT: Save your configuration parameters using the Update > Backup feature with the USB port on the UCB before performing a firmware update. Refer to "Connecting your Flash Drive" and "Performing a System Configuration Backup" for details.
Connecting Your Flash Drive if Performing a Firmware Update
When a flash drive is connected to the UCB USB port, "USB: Wait" appears.
Figure: USB Port Connection Display
The LCD shows "USB: Wait" on the top line and "Scan 0" on the bottom line, with ENTER, CANCEL, and JOY buttons below.
NOTE: If "USB: Wait" does not appear, ensure the flash drive is properly connected and compatible with the UCB.
After a few seconds, the UCB displays "USB: OK". The "Scan" number indicates files and folders compatible with the UCB.
Figure: USB Scan Display
The LCD shows "USB: OK" on the top line and "Scan 18" on the bottom line, with ENTER, CANCEL, and JOY buttons below. The flash drive can remain connected after the scan. Use "ENTER", "CANCEL", or joystick to navigate.
Performing a System Configuration Backup
Insert your flash drive into the USB port. Navigate to the Update > Backup menu and press "ENTER".
Figure: Backup Menu Option Display
The LCD shows options like: >Backup, Restore, with ENTER, CANCEL, and JOY buttons below.
"BKP: Wait" appears during backup, with a flashing colon (:) and increasing percentage. Backup completes in ~30 seconds, displaying "BKP: OK" and 100%.
Figure: Backup Complete Display
The LCD shows "BKP:OK" on the top line and "bCfg 100" on the bottom line.
You can remove the flash drive. A comma-separated value (.csv) restoration file is created, named from the UCB's date and time settings. File size is typically less than 30 KB.
Figure: Restoration File Name Structure Example
An example file name is RTU_2013-11-30T114609.csv, indicating Year, Month, Day, Hour (Military Time), Minute, Second. This file can be used to restore configuration after upgrades or setpoint changes via the Upgrade > Restore feature. The Partial Cloning feature allows transferring configuration parameters from one unit to another using a backup file. Full Cloning is for UCB board replacement.
Updating Smart Equipment™ Software
Auto Update (FWU: Firmware Update)
Version 3.3.1.186 introduced the "Auto Update" (Firmware Update) feature. This feature checks for firmware mismatches on control boards (Economizer, FDD1, FDD2, 4-Stage) and automatically pushes version 3.3.1.186 to all applicable boards. This process can take 7-30 minutes.
The Auto Update feature required a change in UCB memory size. Firmware version 3.3.1.186 can be installed on older (4MB memory) boards but will not perform Auto Update. Firmware updates must be performed twice back-to-back on 3.1 level (8MB) boards with older 3.0 level firmware.
Figure: Smart Equipment™ Board Revision
A diagram of the Smart Equipment™ board shows locations for "Microprocessor Size Indication" and "SSE Board Revision Location".
| UCB | v3.0 | v3.1 |
|---|---|---|
| 2 stage w/o Comm | 1089066 / SE-SPU1002-1 | 5132364 / SE-SPU1002-3 |
| 2 stage with Comm | 1089070 / SE-SPU1012-1 | 5132365 / SE-SPU1012-3 |
| 1 stage w/o Comm | 1149498 / SE-SPU1001-1 | 5132366 / SE-SPU1001-3 |
| 1 stage with Comm | 1149499 / SE-SPU1011-1 | 5132367 / SE-SPU1011-3 |
CAUTION: If power is lost during Auto Update, the UCB will re-attempt updating once power is restored (90 seconds after normal startup) up to 5 times. If it reaches the maximum, manual USB update is needed. Do not use the joystick or buttons during auto update. If auto update fails, a brief message, blinking Fault LED, and "firmware mismatch" alarm will display, requiring manual update.
