DEVIreg™ 850 IV
7 Installation instruction
1�3 Possible alarms during operation
Clogged drain
Description: When clogged drain warning has been enabled, an alarm is raised
when the system constantly has been detecting moisture for 14
days.
If the DEVIreg™ 850 controls more than 1 system, and prioritiz-
ing 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 up-prioritized system is not heating)
Solution: - Check gutter and down pipes for any obstacles preventing the
melting water to flow away.
- Check if sensors are covered with dirt.
Missing sensor
Description: When the connection to a sensor is lost, the DEVIreg™ 850 alarms
the user. At the same time the DEVIreg™ 850 automatically switch-
es the system to “Constant Off” mode, and user interaction with the
DEVIreg™ 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.
