ntroductory information
For your safety
Please follow these safety instructions closely to prevent accidents and
material losses.
In emergencies
Hmmediately isolate the mains
electrical supply, e.Ăg. by removing
a separate mains fuse or by means
of a mains electrical isolator
(unless you smell gas).
Hn case of fire, use an appropriate
fire extinguisher.
Work on t e equipment
nstallation, initial start-up,
inspection, maintenance and repairs
must only be carried out by a
competent person (heating engineer/
refrigeration specialist/installation
contractor).
Before working on the equipment/
heating system, isolate the mains
electrical supply (e.Ăg. by removing a
separate mains fuse or by means of
a mains electrical isolator) and
safeguard against unauthorised
reconnection.
Installation of additional
components
The installation of additional
components which have not been
tested together with the boiler can
adversely affect the boiler function.
Our warranty excludes and we
accept no liability for damage caused
by the installation of such
components.
Boiler room conditions
HDo not use rooms where the air is
polluted with halogenated
hydrocarbons (e.Ăg. as contained in
aerosols, paints, solvents and
cleaning agents)
HDo not use rooms with high levels
of dust
HDo not use rooms with
permanently high levels of
humidity
HThe room should be frost
protected
HMax. ambient temperature 35ĂºC

This is set to winter operation, i.āāe.
central heating and DHW are
operated (if installed) in accordance
with the set switching times.
Switc ing times
Central heating and DHW are
operated at a standard temperature
between 06.00 and 22.00 hrs.
Central heating is operated at a
reduced temperature between 22.00
and 06.00 hrs.
Basic setting
Open the flap, press "F" and follow
the instructions in the display screen.
All modified values are returned to
their factory settings.
Selecting t e operating mode
Select an operating mode with the rotary selector according to your
requirements for:
Hdirectly connected heating circuit (heat pump)
and
Hheating circuits with mixers.
Please note:

Quick start
C anging t e room temperature
n the "as delivered condition" the standard temperature is set to 20 ºC and
the reduced temperature to 16 ºC, see program on page 14. You may change
these temperatures in the range from -5 to +5 ºC according to your
requirements using the rotary selectors "s" and "m" , without modifying the
programmed values.
Standard temperature
Example
For those times when you are at home and wish to have a
comfortable ambience.
The central position means no change.
Each increment corresponds to a change of -1 ºC or +1 ºC,
i.e. at a standard temperature of 20 ºC, turning the dial
fully clockwise would result in a temperature of 25 ºC.

Temperatures current new
Standard: +0.0 +5.0
Reduced temperature
Example
For night-time and other times when you are not in the
living accommodation.
The central position means no change.
Each increment corresponds to a change of -1 ºC or +1 ºC,
i.e. at a reduced temperature of 16ºC turning the dial fully
anti-clockwise would result in a temperature of 11 ºC.

Switching on and off
Starting up t e eating system
The initial start-up and matching of the control unit to local conditions and
the structural characteristics of the building must be carried out by your
heating contractor.
1. Check the pressure of your
heating system on the pressure
gauge:
Minimum system pressureĂ1.2Ăbar.
The system pressure is too low, if
the needle of the pressure gauge
indicates below 1.2Ăbar ć please
notify your local specialist.
2. Switch on the mains voltage,
e.āg. at a separate fuse or a mains
electrical isolator.
3. Switch on the system On/Off
switch next to the control unit.
Your heat pump is now ready to
operate.
System s utdown
f you intend shutting down your heat pump for a certain
time, e.āāg. during a summer holiday, set the operating
mode selector to "Off" (see "Selecting operating modes"
on pageĂ6).
Switch off your heat pump, if it will not be needed for
longer periods of time (several months).
We recommend that, before taking the heat pump out of
operation for longer periods, you get in touch with your
local specialist. Where necessary, this contractor can take
certain measures, e.āāg. protecting the system against frost.
1. Switch on the system On/Off
switch next to the control unit.
As the system is now isolated, the
heating system has no frost
protection, and the pumps will not
be switched on to protect them
against seizing up.
2. solate the mains voltage, e.āg. by
removing a separate fuse or by
means of a mains electrical
isolator.
All settings remain intact.

Heat pump/heating circuit settings
General
All control circuits are displayed as symbols, when the programming unit flap
is closed.
After C for "Program" has been pressed, and when the programming unit
flap is open, all control circuits will be called up via alpha keys. Depending on
the system version, the following options are offered:
H A "Heat pump"
H B, C "DHW cylinder" (domestic hot water cylinder)
H B, C, D, E"Mixer" (heating circuit with mixer), "Solar collector"
A directly connected heating circuit (without mixer) will not be displayed, as it
is regulated via the "heat pump" settings.
By way of example for all possible system versions, this manual describes a
heat pump system comprising:
Hone DHW cylinder and
Hone heating circuit with mixer
Set up all other control circuits in the same way.
The settings for heat pumps and heating circuits with mixers are identical in
type and function. Therefore, the following section describes both.

Heat pump/heating circuit settings
Setting t e current operating mode
A setting change at this point only affects a change to the operating mode
until the next change-over initiated by the timer program.
Operating modes of eat pump/ eating circuit:
"Standard" The heat pump/heating circuit will be regulated to the standard
temperature.
"Off" The heating circuit is switched off. The heat pump will only be
activated for heating DHW (if set) and to protect the system
against frost.
"Reduced" The heat pump/heating circuit will be regulated to the reduced
temperature.
"Fixed value Only for systems with a heating water buffer storage unit:
regulator" The storage unit will be heated independent of outside
temperature to the fixed value set by your specialist
(e.āg. during low tariff times).
Press the following keys:
1. C for "Program".
2. A for "Heat pump"
or
