Operation Instructions

Possible alarms during operation
Clogged drain Description: When clogged drain warning has been enabled, the system constantly has
been detecting moisture for 14 days.
If the GX™ 850 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)
Solution: - Check gutter and down pipes for any obstacles preventing the melting
water to fl ow away.
- Check if sensors are covered with dirt.
Missing sensor Description: When the connection to a sensor is lost, the GX™ 850 alerts the user. At the
same time the GX™ 850 automatically switches the system to “Constant Off ” mode, and user interaction with the GX™ 850 is needed.
Solution: - Acknowledge error and go to “Installer Site” in the menu system and
select “Change System”.
- Contact your local installer to get a replacement.
New sensor added Description: When a new sensor is added, the GX™ 850 alerts the user and at the same
time automatically switches to “Constant Off ” mode. User interaction is needed in order to correct the error.
Solution: Acknowledge error and go to “Installer Site” in the menu system and select
“Change System”.
Sensor malfunction Description: When something is wrong with the readings from connected sensors to
the GX™ 850, an alarm is raised.
Not all error prone sensors can be discovered using this feature!
Solution: - Acknowledge error and go to “Installer Site” in the menu system and
select “Change System”.
- Contact your local service centre to get a replacement.
