3. Continue to press/hold ENTER/NEXT until MEM CLEAR and DONE appear, followed by the configured operational mode setting.
In addition, the following occurs:
• The operational settings can be adjusted
• The Astronomical zone defaults to AL (Alabama) and CNT (center).
• The Astronomical user offsets are set to zero.
• All scheduled switching activity settings are deleted.
• The established normal output current value is deleted.
Current Detection
This ET8215B monitors the electrical current drawn by each output load and alerts the user when the current varies from an established value
(i.e. a bulb has burned out). When the timer outputs first turn on after installation the output current is continuously checked for 15 minutes to
establish a normal operating current value which the timer stores in memory.
NOTE: It is necessary for all load devices to be operating properly so the timer can detect the correct current value.
After this initial time period the timer regularly checks the output currents and if either output is 10% below the stored value for more than 1
minute the timer sends a fault message via the cellular link and shows one of the following messages on the display:
•
LF1 if the low current was detected on output #1.
•
LF2 if the low current was detected on output #2.
•
LF12 if current levels of both outputs are lower than normal.
Once the current level returns to the stored normal value, the corresponding error message disappears.
Updating Firmware
A properly prepared USB memory stick is needed to complete this procedure.
NOTE: Keep all update files in the root directory of the memory stick.
Follow this procedure to update the firmware on the ET8215B.
1. Plug the USB memory stick into the USB port on your computer.
2. Go to intermatic.com and download the new software file (SW-000029-X.bin) into the root directory of the memory stick.
3. Rename the file with an 8 character name – Example et8215r3.bin (keep the “.bin” extension).
4. Open the Notepad program on the computer and create a new file called download.txt.
5. On the first line of this new file type the file name created in step 3 and save this new file.
6. Copy this file also onto the USB stick.
7. Remove the USB memory stick from the computer and then plug it into the USB port on the front panel of the ET8215B timer.
8. Press the reset button. The new software downloads for 3 to 4 seconds and then the ET8215B restarts.
9. Remove the USB memory stick from the USB port. The ET8215 returns to normal operating mode. The firmware update is complete.
