IBC VX “Remote offline” display message
Remote offline
The manual lists this warning when a boiler configured as the Master in a network cannot detect any subordinate boilers. It appears on networked (cascade) installations rather than single-boiler homes.
Applies to
This warning message is shown by the V-10 touchscreen controller on VX Series residential boilers (VX 110, VX 150 and VX 199), as documented in IBC Installation & Operating Manual — VX 110 / VX 150 / VX 199, doc 120-347E6, sections 9.2–9.4.
Controller: V-10 touchscreen controller. Source manual: 120-347E6 (2026-08-07).
Why a code is not a diagnosis
The warning does not say whether a subordinate boiler is powered down, the network wiring is broken, or the network settings changed. The manual's checks cover wiring, power state and IP/network settings on each unit.
Safe things to observe
- Check that every boiler in the plant has power and shows a normal display.
- If you are not responsible for the boiler plant, note the warning and report it to the building manager or your service provider.
Do not
- Do not re-configure boiler network settings yourself.
How professional service helps
- A technician verifies network wiring, subordinate power state, IP settings and Network IDs across the cascade.
- Faulty connections or settings are corrected so the master can see its subordinates again.
