Introductory information
For your safety
Please follow these safety instructions closely to prevent accidents and
material losses.
In emergencies
Immediately isolate the mains
electrical supply, e.g. by removing
a separate mains fuse or by means
of a mains electrical isolator
(unless you smell gas).
In case of fire, use an appropriate
fire extinguisher.
Work on the equipment
Installation, initial start−up,
inspection, maintenance and repairs
must only be carried out by a
competent person (heating
engineer/refrigeration specialist/
installation contractor).
Before undertaking work on the
equipment/heating system, isolate
the mains electrical supply (e.g. by
removing a separate mains fuse or
by means of a mains electrical
isolator) and safeguard against
unauthorised re−connection.
Installation of additional
components
Installation of additional components
which have not been tested together
with the boiler can adversely affect
the boiler function.
Our warranty does not cover
damage caused by the installation of
such components, nor do we accept
liability for such damage.
Boiler room conditions
Do not use rooms where the air is
polluted with halogenated
hydrocarbons (e.g. as contained in
aerosols, paints, solvents and
cleaning agents)
Do not use rooms with high levels
of dust
Do not use rooms with permanently
high levels of humidity
The room should be frost protected
Max. ambient temperature 35ºC

Changing the room temperature
In the "as delivered condition" the standard temperature is set to 20 ºC and the
reduced temperature to 16 ºC (see page 16). You may change these temperatures
according to requirements using the rotary selectors "s" and "m".
Normal temperature
Example
For those times when you want to be cosy at home.
The central position means no change. A setting range of
5 to +5, i.e. at a standard temperature of 20 ºC, turning
the selector to the end stop clockwise would
result in 25 ºC.

Switching on and off
Starting the heating 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 local
specialist.
Before you switch on a heating system which has been switched off for
longer periods it would be advisable to contact your local specialist.
1. Check the pressure of your
heating system on the pressure
gauge:
Minimum system pressure1.2bar.
The system pressure is too lowif
the needle of the pressure gauge
indicates below 1.2bar  please
notify your local specialist.
2. Switch on the mains voltage, e.g.
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.
5592 415GB

13
Switching on and off
System shutdown
If you intend shutting down your heat pump for a certain
time, e.g. during a summer holiday, set the operating
mode selector to "Off" (see "Selecting operating modes"
on page7).
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.g. 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. Isolate the mains voltage, e.g. by
removing a separate fuse or by
means of a mains electrical
isolator.
All control unit settings remain
active.

Heat pump/heating circuit settings
General
All control circuits controlled by the control unit are displayed as symbols,
when the programming unit flap is closed.
After key Cfor "Programme" has been pressed, and when the
programming unit flap is open, all control circuits will be called up via the
alpha keys. Depending on the system version, the following options are
offered:
A"Heat pump"
B, C"DHW cylinder" (domestic hot water cylinder)
B, C, D, E"Mixer" (heating circuit with mixer), "Solar collector"
A directly connected heating circuit (without mixer) will not be shown in the
display field, 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:
One DHW cylinder and
One heating circuit with mixer.
Implement settings for all further control circuits in accordance with those
described here.
The settings for heat pumps and heating circuits with mixers are in type and
function identical. Therefore, the following section describes both.

Heat pump/heating circuit settings
Setting the current operating mode
This option for setting the operating mode only affects this change of
operating mode until the next change activated by the timer program.
Operating modes of heat pump/heating circuit:
"Normal" Heat pump and/or heating circuit are regulated to the set
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" Heat pump and/or heating circuit are regulated to the set
reduced temperature.
"Fixed value Only for systems with heating water buffer storage unit:
regulator" The heating water buffer storage unit will be heated
independent of outside temperature to the fixed value set by
your specialist (e.g. during low tariff times).

Changing switching times
The central heating can be changed between operating modes according to
the switching time settings.
You can select identical switching times for all weekdays or individual ones
for every weekday.
When setting the switching times, take the response time of your heating
system into consideration. Select correspondingly earlier start−up and
switch−off times.
