1 Safety and
usage instructions
1.1 General safety notes
Carefully read the operating manual before commissioning the units for the first time. It contains
useful tips and notes such as hazard warnings to
prevent personal injury and material damage.
Failure to follow the directions in this manual not
only presents a danger to people, the environment
and the system itself, but will void any claims for
liability.
Keep this operating manual and the refrigerant
data sheet near to the units.

1.2
This section provides an overview of all important
safety aspects for proper protection of people and
safe and fault-free operation.The instructions and
safety notes contained within this manual must be
observed in order to prevent accidents, personal
injury and material damage.
Notes attached directly to the units must be
observed in their entirety and be kept in a fully
legible condition.
Safety notes in this manual are indicated by symbols. Safety notes are introduced with signal words
which help to highlight the magnitude of the danger
in question.
DANGER!
CAUTION!
This combination of symbol and signal word
warns of a potentially hazardous situation,
which if not avoided may cause injury or material and environmental damage.
NOTICE!
This combination of symbol and signal word
warns of a potentially hazardous situation,

serious injury.
Dangers of failure to observe
1.4
the safety notes
Failure to observe the safety notes may pose a risk
to people, the environment and the units. Failure to
observe the safety notes may void any claims for
damages.
In particular, failure to observe the safety notes
may pose the following risks:
n The failure of important unit functions.
n The failure of prescribed methods of mainte-
nance and repair.
n Danger to people on account of electrical and
mechanical effects.
1.5 Safety-conscious working

1.6 Safety instructions for the operator
The operational safety of the units and components is only assured providing they are used as
intended and in a fully assembled state.
n The units and components may only be set up,
installed and maintained by qualified personnel.
n The existing regulations concerning accident
prevention must be adhered to.
n Do not operate units or components with
obvious defects or signs of damage.
n Contact with equipment parts or components
can lead to burns or injury.
n Ensure that electrical energy does not pose a
risk.
n Regulations of the VDE and the local energy
supply company must be adhered to.
NOTICE!
Material damage due to mineral oils!
Mineral oil products permanently damage
EPDM seal elements; the sealing properties
may therefore be lost. We do not take responsibility or provide warranty replacements for
damage caused by seals that are damaged in
this way.
– It is essential that you prevent EPDM from
coming into contact with mineral oil substances.
– Use a lubricant that is free of mineral oil
and has a silicone or polyalkylene basis,
such as Unisilkon L250L and Syntheso
Glep 1 made by Klüber, or a silicon spray.
1.7 Safety notes for installation and inspection tasks
n The operator must ensure that all inspection
and installation work is carried out by authorised and qualified personnel who have thoroughly read the operating manual.
n Works on the pump/system may only be car-
ried out whilst at a standstill as a matter of principle.
n Appropriate hazard prevention measures must
be taken to prevent risks to people when performing installation, repair, maintenance or
cleaning work on the units.
n The setup, connection and operation of the
units and its components must be undertaken
in accordance with the usage and operating
conditions stipulated in this manual and comply
with all applicable regional regulations.
n Regional regulations and laws as well as the

Sliding hot water temperature
Adjusts the domestic hot water target temperature
to the temperature level of the buffer tank for preheating systems that are discharged from the
Buffer tank without re-heating
(Tww target = TVL - 5 K).
This function works according to fixed parameters.
No further settings are required. If this function is
active in operation, this is symbolised by a flashing
temperature.
The function can only be activated or deactivated.
Fig. 24: Sliding hot water temperature
In cascading operation, this function is recommended only in exceptional cases because
high temperature fluctuations occur at the dispensing connection when switching the modules. If the function is selected despite this, it
must be activated in the master and slave controllers. The function works independently in
each of the controllers.

REMKO fresh water station Controller
Thermal disinfection
The fresh water station provides higher domestic
hot water temperatures, in order to kill dangerous
germs. At the same time, the circulation pump is
activated, as long as the circulation function was
activated. If the circulation function was not activated, only the domestic hot water target temperature in the defined time window is increased to the
disinfection temperature.
Fig. 26: Cascade
The cascade function must be activated in both
controllers; one controller must be configured as
the master (MA) and the other as the slave (SL).
The master controller forwards the following information to the slave:

troller but one of the connected components.
– The following notes for identifying errors
refer to the most common causes of errors.
– Do not send the controller in until you are
sure that none of the causes of errors
described here apply.
General errors
