1. General information
With the purchase of this system you have made a
decision for a modern and economical heating sys-
tem. Continuous quality control and enhancements,
as well as function tests in the factory, guarantee a
technically flawless device.
Please carefully read these documents. They con-
tain important information for the safe and thrifty op-
eration of the system.
Safety instructions
Installation and service work can - due to the high
system pressures, high temperatures and live elec-
trical parts - be associated with hazards and may
only be performed by specialists. Heat pumps may
only be installed by capable specialists and only put
into operation by specialists who have been special-
ly trained by Hoval for this purpose. Power supply to
the system should be switched off when work is be-
ing performed on the heat pumps and safeguarded
against inadvertent reswitching. Moreover, all safety
instructions in the respective documents, as well as
on adhesive labels on the heat pumps themselves
and in other applicable safety regulations, must be
observed.
Heating system
Control water level
Control the water level of the heating system regurarly
following the instructions described on page 41.
Sound Emissions
The Hoval Belaria®heat pump runs exceptionally
smooth, thanks to its engineering design. Neverthe-
less, it is important that the heating room is located
as far away from noise-sensitive living areas and
closed off with a tightly sealing door.
Drying out of buildings or respectively the heat-
ing of screed
The heat pump is not designed for the increased
heat requirement necessary for drying out buildings
or respectively the heating of screed. For safety rea-
sons the compressor is switched off with return tem-
peratures below +18°C. The drying out of buildings
must be accomplished by other on-site devices as
needed.
Service and Maintenance
Regularly scheduled maintenance and the examina-
tion and care of all important system parts ensures
safe and thrifty system operation in the long run.
We therefore recommend concluding a service and
maintenance contract with Hoval Customer Service
for this purpose.
Cleaning
If necessary, the Belaria®heat pump can be cleaned
with a damp cloth. The usage of cleaning agents is
not recommended. The condensate discharge must
be checked periodically for blocking and the evapo-
rator for soiling.
Installation of Additional Components
The installation of additional components which
have not been tested as a part of the system can
cause functional impairment. Hoval will assume no
warranty or liability coverage for any resultant dam-
ages.
Installation location
• Sufficient air supply must be provided (according
to EN 378 part 1-4)
• No heavy dust accumulation
• No permanently increased humidity (below 50%
r.h. at a room temperature of 18°C
• Frost protection
Outside Installation
The installation place must be carefully selected.
The following boundary conditions must be kept:
• The installation place should be selected in such
a way that air intake and outlet is not hampered or
obstructed by snow, leaves etc.
• There should be provided sufficient space for in-
take and outlet as well as for operation and main-
tenance.
• Air short-circuit must be avoided.The space neces-
sary for intake and outlet must be always provided.
The minimum distances apply only to the indicated
example. Under unfavourable conditions (e.g. air
short-circuit because of wind influence) the heat
pump should be provided with a bilateral blow.
• Intake air must be completely free from aggressive
substances like ammonia, sulphur, chlorine etc.
• The installation place should not be situated un-
der the living room or bedroom because of sound
emission and be placed at sufficient distance from
the neighbouring building. (elaborate calculation)
• Is not recommended to install the heat pump into
wall niches (air short-circuit, sound echo).

2. Operation
With the main switch and control switch activated,
the Belaria®heat pump is switched on and off au-
tomatically by means of the fully automatic heating
control TopTronic®T.
Main switch
The main switch activates the control current as
well as the rotary current for the heat pump and the
electric heating element.
Control switch
With this switch the heating control TopTronic®T of
the heat pump is activated. The green operation
lamp on the contol box is shining.

3. Heating system control
3.1 What is the function of the heat generator controller TopTronic®T
The heat generator controller is, in conjunction with the temperature sensor
connected to it, so to speak, the brain of the heating system. Its main func-
tions are:
- maintaining the desired room temperature independently of the outdoor
temperature
- heating or cooling the living space when required
- produce warm water (e.g. for showering) only when required
- displaying information
further functions:
- Input of desired temperatures and operating modes
- Turn the burner ON/OFF
- Temperature monitor
The correct settings for the heating system have already been applied by
Hoval, or the installer, during commissioning. Any changes to those settings
should only be carried out if you go away on a trip or if your home is to cold or
too warm. An overview of the most frequent questions/answers can be found
on pages 8, 15 and 16 of these instructions.
3.2 How you can save energy
For your benefit and for the environment
Using energy more efficiently by avoiding unnecessary losses:
With little effort you can optimise the operation of your system and make it
worth it.
In autumn, it is worth while turning the heating off again on warm days
This prevents the heating system from producing unnecessary heat in the
morning, due to low outdoor temperatures, and overheating the house. Turn-
ing the heating on or off depending on the weather conditions is one of the
most effective energy saving measures. If you want to save yourself going
down the basement, you may want to consider acquiring a "remote control"
from Hoval, which will allow you to operate and control the heating comfort-
ably from your living room.
3.3 Basic display
The basic display shows the day of the week, date and time of the day, as well
as the current temperature of the heat generator or any other temperature
(depending upon installation).

is required
Press for 3 seconds and set the additional loading time
(page 29).
From now on, hot water but
no heating is required
Set operating mode to 
"SUMMER" with
���
heating off, only hot
water) (pages 15,18).
Suddenly, there is no heating
or hot water; it is cold.
Check the heat generator for alarms and consult a heating engineer, if
necessary. Check main switch (see page 5) and gas supply.
The room temperature set-
point requires frequent
adjustments in the heating
operation because it is too
cold or too hot
Change the set heating curve (pages 26-28).
Changing the heating curve is not sensible if your system is fitted with a
room sensor (or room station) and an outdoor sensor. The correct set-
tings for the heating curve are then provided automatically. Consult a
specialist, if necessary.
Today, I will be absent for se-
veral hours during the day
Set the operating mode to  "ABSENT TIL" with
���
and set the re-
turn time (pages 15-17).
I am travelling for a short pe-
riod of time (e.g. 3 days)
Set the operating mode to "HOLIDAY TIL" with
���
and set the re-
turn date (pages 15-17).
I will be travelling for an inde-
finite period of time
Set the operating mode to  "RED. HEATING" with
���
.
When returning, set the operating mode to "AUTOMATIC" (pages

energy and money if the rooms are not heated or less heated during your absence.
ENERGY
To save energy, we recommend that the desired room temperature (day/ night)
should not be set to below 16°C. During the cold season, the functions «Holiday
till” and «Stand by” should not be used. At room temperatures below 16°C, supple-
mental heating is effected via additional electric heating.This would result in higher
electricity consumption.
The following table is intended as a guide for finding the best operating mode for
each particular case:
See following pages for a detailed description on how to set the operating modes.
You can return to the "AUTOMATIC" function (normal heating or cooling operation) at any time by "pressing"
���
for 3 sec.
