Safety
The unit is operationally safe when used for the intended pur-
pose. The construction and design of the unit conform to the
state of the art, all relevant DIN/VDE regulations and all relevant
safety regulations.
Every person who performs work on the unit must have read and
understood the operating manual prior to starting any work. This
also applies if the respective person has already worked with such
a unit or a similar unit or has been trained by the manufacturer.
Every person who performs work on the unit must comply with
the applicable accident prevention and safety regulations. This
applies in particular to the wearing of personal safety gear.
DANGER!
Danger of fatal injury due to electric current!
Electrical connections may be installed only by qualied
electricians.
Before opening the unit, disconnect the system from the
power supply and secure it from being switched back
on!
WARNING!
Observe the relevant EN, VDE and/or applicable local
safety regulations during the installation and during all
electrical work.
Observe the technical connection conditions of the re-
sponsible power supply company!
WARNING!
Only qualied technicians (trained heating, cooling, re-
frigerant and electrical technicians) may perform work
on the unit and its components.
ATTENTION
Setting work on the heating and heat pump regulator is
only permitted for authorised service personnel and spe-
cialist companies who or which have been authorised by
the manufacturer.
WARNING!
Observe safety labels in the unit.
ATTENTION
For safety reasons: Do not disconnect the unit from the
power supply, unless the unit is being opened.
ATTENTION
Plug X5 and screw terminals X4 of the heating and heat
pump regulator are under low voltage. Use only original
sensors from the manufacturer (protection class II).
ATTENTION
Circulating pumps may be controlled only by the heating
and heat pump regulator. Never shut o circulating pumps
externally.
Functioning of the heating
and heat pump regulator
The heating and heat pump regulator consists of an operating el-
ement and an electronic control. This assumes control of the en-
tire heat pump system, the domestic hot water preparation and
the heating system. It automatically recognises the connected
heat pump type.
The weather-controlled heating curve of the heating system with
corresponding lowering and boosting times is set at the heating
and heat pump regulator.
The domestic hot water preparation can be carried out via the
thermostat (to be set at the customer) or temperature sensor (do-
mestic hot water tank accessories or scope of supply) in accord-
ance with requirements. The domestic hot water preparation via
a temperature sensor enables intelligent, adaptive domestic hot
water preparation with a high level of comfort.
Low-voltage and 230V signals are eectively isolated by the heat-
ing and heat pump regulator. This ensures maximum interference
immunity.
Intended use
The unit may be used only for the intended purpose. This means:
• •for controlling the heat pump and associated system com-
ponents.
The unit may be operated only within its technical parameters.
ATTENTION
The heating and heat pump regulator may only be oper-
ated in conjunction with heat pumps approved by the
manufacturer and accessories approved by the manufac-
turer.
Exclusion of liability
The manufacturer will not be liable for damage resulting from un-
authorized use of the unit.
The manufacturer’s liability will also be voided in the following
cases:
• •if work is performed on the unit and its components in a
manner that does not comply with the terms of this operating
manual;

improper manner;
• •if work is performed on the unit that is not described in this
operating manual, and this work was not expressly approved
in writing by the manufacturer;
• •if the unit or components in the unit are modied, rede-
signed or removed without the express written permission of
the manufacturer.

SETTING THE DOMESTIC HOT WATER
TEMPERATURE
Set the required domestic hot water temperature (=set-
point value): 30 °C.
Terminate input. This saves the required temperature.
NOTICE
In conjunction with domestic hot water tanks recom-
mended by the manufacturer, your heat pump can gener-
ate domestic hot water temperatures which are around 7
K lower than the maximum ow temperature of your heat
pump.
NOTICE
If a domestic hot water temperature is set which cannot be
attained, the heat pump will initially switch to “Error high
pressure”. This is followed by a self-resetting fault (If heat-
ing is required, this will also be operated). After 2 hours
have passed, the domestic hot water preparation starts
again. Nevertheless, the program of the heating and heat
pump regulator automatically lowers the setpoint value for
this by an initial 1 °C. If this setpoint temperature cannot
be attained either, the process is repeated until a tempera-
ture can be attained.
The set desired value remains unaected and is dis-
played unchanged.
SETTING THE DOMESTIC HOT WATER MODE OF

NOTICE
When programming, ensure that the time periods which
you specify in the area “Time progams domestic hot wa-
ter preparation” are off times. The domestic hot water
preparation is switched o in the time periods entered.
If you require domestic hot water despite active o-time(s), you
can select a domestic hot water preparation and then terminate it
again via the function “High-speed charge” by bypassing the pro-
grammed o-time(s).
