Thermal-Grid DL2 FAQs:
What does the “disconnected” alarm mean?
Data is not reaching the server(web-based database). This could be something with your Internet connection, local network, router, switch, or the DL2. Troubleshooting starts with the simple things. Is the power light on? Is the red bar flashing? (note: if so, data is being gathered from the controller and is stored locally, ready to be uploaded when connection is restored). Is there Internet access from other computers on the network? Is there an Internet connection on the Ethernet cable connected to the DL2? ( possible test: Check that a laptop(wireless off) can reach the Internet using the cable that is plugged in to the DL2)
What do I do if I see an alarm?
- Alarms in the portfolio timeline are alerts to a condition that is out of the ordinary and should be noted.
- Emailed alarms are conditions that have existed long enough(default 1 Hour) that they should be observed by a installer/service person
Some alarms need immediate action while others may be a statement that a condition warrants some attention. There are certain hardware alarms that come as defaults such as broken wiring or sensors(open or closed circuits).
What do I do if I see a "negative delta" alarm?
This can be a common alarm on a collector loop where upon startup there may be cold fluid is circulated upon startup. Depending upon system type it may be normal for a brief negative delta but not ongoing. Check that the actual sensor locations are correctly identified on the site diagram or web-schematic.
What do I do if I get frequent email alarm notifications about condition that my installer considers normal?
The “Owners” users can opt out of receiving email notification. The duration of the alarm condition existing before an email is sent can also be adjusted. The technician can extend the “Escalation delay”(default is 1 hour/3600 seconds) in the alarm setting menu.
