Functioning of the heating
and heat pump regulator
The heating and heat pump regulator consists of an operat-
ing element and an electronic control.This assumes control
of the entire heat pump system, the domestic hot water
preparation and the heating system. It automatically recog-
nises 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 (domestic hot water tank accessories or scope of
supply) in accordance with requirements.The domestic hot
water preparation via a temperature sensor enables intelli-
gent, adaptive domestic hot water preparation with a high
level of comfort.
Low-voltage and 230V signals are effectively isolated by the
heating and heat pump regulator.This ensures maximum in-
terference immunity.
Intended use
The unit may be used only for the intended purpose. This
means:
•for controlling the heat pump and associated system
components.
The unit may be operated only within its technical param-
eters.
ATTENTION
The heating and heat pump regulator may only be
operated in conjunction with heat pumps approved
by the manufacturer and accessories approved by
the manufacturer.
Exclusion of liability
The manufacturer will not be liable for damage resulting
from unauthorized use of the unit.
The manufacturer’s liability will also be voided in the follow-
ing cases:
•if work is performed on the unit and its components in a
manner that does not comply with the terms of this op-
erating manual;
•if work is performed on the unit and its components in
an 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 permis-
sion of the manufacturer.

Safety
The unit is operationally safe when used for the intended
purpose. 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 al-
ready 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 regula-
tions. 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 appli-
cable local safety regulations during the in-
stallation and during all electrical work.
Observe the technical connection conditions
of the responsible power supply company!
WARNING!
Only qualied technicians (trained heating,
cooling, refrigerant and electrical techni-
cians) may perform work on the unit and its
components.
ATTENTION
Setting work on the heating and heat pump regu-
lator is only permitted for authorised service per-
sonnel and specialist 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 (pro-
tection class II).
ATTENTION
Circulating pumps may be controlled only by the
heating and heat pump regulator. Never shut off cir-
culating pumps externally.
ATTENTION
Never shut off heating circle to the heat pump
(frost protection).
ATTENTION
Use only accessories provided by or approved by
the manufacturer.
Care of the unit
The outer surfaces of the unit can be cleaned with a damp
cloth and household cleaning products.
Do not use cleaning or care products that contain abrasives,
acids and/or chlorine. Such products would destroy the sur-
faces and could also damage the technical components of
the unit.

The external sensor is a function-critical accessory and in-
cluded in the scope of supply.
NOTICE
If the external sensor is not installed or defective,
the heating and heat pump regulator automatically
sets the external temperature to -5 °C. The status
display of the operating element lights up red, the
screen of the operating element reports a fault.
ATTENTION
Mount the external sensor on the north or north-
east side of buildings. The sensor must not be ex-
posed to direct sunlight.
Open the housing of the external sensor and align ≥ 2
m over the base of the fastening point. The cable
gland must point to the base…

NOTICE
Dowels and screws for fastening the external
sensor are not included in the scope of supply.
Loosen cable gland from the housing of the external
sensor, lead the 2-wire cable (Ø ≤ 1.5 mm² per wire,
cable length ≤ 50 m) through the cable gland into the
housing…
Clamp on cable, tighten cable gland and close the hous-
ing of the external sensor.
hot Water sensor
The domestic hot water sensor is an optional accessory and
only functionally-relevant for a separate domestic hot water
tank. You may only use domestic hot water sensors which
have been approved by the manufacturer of the heat pump.
ATTENTION
The domestic hot water tank must be lled before
connecting the domestic hot water sensor to the
heating and heat pump regulator.
If not already prepared at the factory, mount the domestic
hot water sensor (Ø = 6 mm) on the halfway level of the
domestic hot water tank – and always above the internal
heat exchanger of the domestic hot water tank.
