Trend IQ controllers run thousands of London buildings. Regular Trend IQ servicing keeps them reliable and flags when an IQ3 or older controller should be upgraded to IQ4.
What Trend IQ servicing includes
The key points to cover:
- Backing up every IQ controller strategy and the supervisor (963 or IQVision)
- Checking network health, comms errors and battery status
- Reviewing alarms, trend logs and time schedules
- Verifying sensor readings against calibrated instruments
- Identifying obsolete hardware and planning IQ4 upgrades
Signs your Trend system needs attention
Frequent comms alarms, controllers dropping offline, lost strategies after power cuts, or plant running out of hours are all warning signs. Book a Trend IQ service before they turn into a plant failure.
