GX-850M ver. IV
When clogged drain warning has been enabled, the system constantly has
been detecting moisture for 14 days.
If the GX-850M ver. IV controls more than 1 system, and prioritizing has
been enabled, the time before clogged drain warning for the down-
prioritized system, can be much longer. The time is only updated when
the system actually is allowed to heat the area (e.g. the higher priority
system is not heating)
- Check gutter and down pipes for any obstacles preventing the melting
water to flow away.
- Check if sensors are covered with dirt.
When the connection to a sensor is lost, the GX-850M ver. IV alerts the user.
At the same time the GX-850M ver. IV automatically switches the system to
"Constant Off" mode, and user interaction with the GX-850M ver. IV is needed.
- Acknowledge error and go to "Installer Site" in the menu system and select
"Change System".
- Contact your local installer to get a replacement.
When a new sensor is added, the GX-850M ver. IV alerts the user and at the
same time automatically switches to "Constant Off" mode. User interaction is
needed in order to correct the error.
Acknowledge error and go to "Installer Site" in the menu system and select
"Change System".
When something is wrong with the readings from connected sensors to the
GX-850M ver. IV, an alarm is raised.
Not all error prone sensors can be discovered using this feature!
- Acknowledge error and go to "Installer Site" in the menu system and select
"Change System".
- Contact your local service centre to get a replacement.
