Group warning
The demineralization
solenoid valve does not
close within the
specified time period.
DI cartridge worn.
No flow through DI cartridge.

Outlettemp. 1 max STOP Group fault alarm
Maximum outlet
temperature cold water
circuit 1 exceeded.
No refrigeration,
Thermal overload.
Check function of the chiller
circuit,
Check installed heat load.
Chiller switches off immediately.
Alarm is saved.
Manual reset.
352
Outlettemp. 1 min STOP Group fault alarm
Outlet temperature cold
water circuit 1 is below
the minimum.
Check function of the tank
heater, check setpoint setting,
ambient temperature too low.
Check tank heater function,
check setpoint, increase ambient
temperature.
Chiller switches off immediately, (Until
V 2.60) (Compressors switch off
immediately). Pumps deactivate via
follow-up time, this would be correct)
Alarm is saved,
Manual reset.
