Hi Pres
High pressure switch active.
Check hot side pump/overflow valve on
high temperature side. Check if there is air
in the hot side water. Check if filter is
blocked on the hot side.
The unit restarts when the pressure drops
below high pressure switch lowlimit again.
After 3rd cut-out the alarm must be
acknowledged to start the unit again.
601
Low pres.
Low pressure switch active.
Check refrigerant charge, expansion valve
and evaporator for ice. Check fan for
obstacles on an air to water evaporator.
The alarm must be acknowledged to start
the unit again.
602
Leakage
Low pressure in brine - Brine pressure
switch active.
Leakage check of the brine system.
The alarm must be acknowledged to start
the unit again.
603
Hi press
High pressure switch repeatedly active.
Check hot side pump/overflow valve on
high temperature side.
The alarm must be acknowledged to start
the unit again.
