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 operation of the system.

Safety instructionsInstallation and service work can – due to the high system pressures, high temperatures and live electri-cal 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 being performed on the heat pumps and safeguar-ded against inadvertent reswitching. Moreover, all safety instructions in the respective documents, as well as on adhesive labels on the heat pumps them-selves and in other applicable safety regulations, must be observed.

Heating systemControl water levelControl the water level of the heating system regurar-ly following the instructions described on page 39.

TransportHeat pumps should never be tilted more than 30° when being transported. The heat pumps may ne-ver be transported on the connection fittings! Only remove the transport packing material after the heat pump is in place at the installation location.

Sound EmissionsThe 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 hea-ting 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 Maintenanceregularly 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.

CleaningIf 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.

Installation of Additional ComponentsThe installation of additional components which have not been tested as a part of the system can cause functional impairment. Hoval will assume no warran-ty or liability coverage for any resultant damages.

Installation locationSufficient 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 °CFrost protection•

Outside InstallationThe installation place must be carefully selected.The following boundary conditions must be kept:• Theinstallationplaceshouldbeselectedinsuch

a way that air intake and outlet is not hampered or obstructed by snow, leaves etc.

• Thereshouldbeprovidedsufficientspacefor in-take and outlet as well as for operation and main-tenance.

• Airshort-circuitmustbeavoided.Thespacene-cessary for intake and outlet must be always pro-vided. 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 aggres-sive substances like ammonia, sulphur, chlorine etc.

• The installationplaceshouldnotbesituatedun-der the living room or bedroom because of sound emission and be placed at sufficient distance from the neighbouring building. (elaborate calculation)

• Isnotrecommendedtoinstalltheheatpumpintowall 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.

An annual check and maintenance of the installati-on by the Hoval customer service is recommended, particularly in respect of preserving any claims un-der guarantee.

Main switchThe main switch activates the control current as well as the rotary current for the heat pump and the electric heating element.

Control switchWith this switch the heating control TopTronic®T of the heat pump is activated. The green operation lamp on the contol box is shining.

Switch for electric heating elementThe following operation modes are possible:0: Electric heating element switched offI: Electric heating element is activated automatical-

ly with the bivalence point falling below and with the occurance of a heating demand.

Heating system control

3.1 What is the function of the heating controller TopTronic® T

The controller is, in conjunction with the temperature sensor connected to it, so to speak, the brain of the heating system. Its main functions are:

- maintaining the desired room temperature independently of the outdoor temperature

- heating 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, 13 and 14 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 daysThis prevents the heating system from producing unnecessary heat in the morning, due to low outdoor temperatures, and overheating the house. Turning 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 comfortably 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).

3.4.3 What to do if...

The following information can be used as a first level support in frequently occurring situations.

Observation

It is too cold

It is too warm

From now on, equal day and night temperatures should be maintained continuously

This evening, the heating should remain on for longer

A larger amount of hot water is required

From now on, hot water but no heating is required

Suddenly, there is no heating or hot water; it is cold.

The room temperature setpoint requires frequent adjustments because it is too cold or too hot

Today, I will be absent for seve-ral hours during the day

I am travelling for a short peri-od of time (e.g. 3 days)

I will be travelling for an inde-finite period of time

In summer, it is too cold or too warm.

Remedy

Set a higher value for the room temperature with and the rotary pushbutton (page 11).

Set a lower value for the room temperature with and the rotary pushbutton (page 11).

Set the operating mode to “HEATING” with (page 13, 16).

Set the operating mode to “PArTY” with and set the desired time (page 13, 15).

Press for 3 seconds and set the additional loading time (page 26).

Set operating mode to “SUMMEr” with (heating off, only hot water) (page 13, 16).

3.8 Heating curve3.8.1 Heating curve (heating characteristic) information

The heating curve describes the flow temperature of a heating system as a function of the outdoor temperature.

The heating curve is preset by the installer *.

Conduct temporary changes to the room temperature settings via the “Day-time room temperature” or “reduced temperature”.

The heating characteristic curve settings should only be changed if the room temperature is not reached over a longer period of time during the heating period.

recommended settings:Floor heating: 0,3 to 0,8radiator heating: 1,0 to 2,0Convector heating: 1,4 to 2,0

Note:You can leave the manual operating mode and the emission monitoring mode at any time by tapping of the operating mode key (return to basic display).

This function key is also used for emission measurement with oil boilers when it is only pressed briefly.Emission measurement must not be activated for heat pumps!

All pumps are operating without restrictions. Available mixers are discon-nected and can be operated manually, if necessary, depending on the heat demand.

CAUTION:- The DHW temperature reaches the level of the temperature setpoint. Scalding hazard if temperature setting too high!- To protect underfloor heating systems against invalid overheating during

manual operation, it is necessary to implement appropriate safety mea-sures (e.g. safety temperature limiter with pump switch-off).

Room station RS-TThe room station rS-T offers additional operating convenience through de-centralised monitoring and intervention options, since every heating circuit can be assigned with its own individual room station. Moreover, the central unit contains various control and regulating functions which can only be activated in conjunction with a room station. The following are some of those functions:- Optimisation functions- Automatic heating curve adaptionSystem specific temperatures and switching times can be checked and mo-dified via five control keys, also allowing the definition of individual system programs.The operation of the room station and the control unit is identical.

Remote setting device with room sensor RFF-TThis auxiliary device monitors the current room temperature and allows the desired room temperature to be corrected.With the integrated operating mode key you can select between continuous heating, reduced heating or automatic mode according to a preset automatic program stored in the central unit.

Heat pump controller Type RAM110A

4. Heat pump controller Type RAM110A

With air/water heat pumps, ice is being formed on the evaporater at outside temperatures below 7 °C. The heat pump controller monitors the formation of frost and initiates the defrosting process if required. With demand-actuated heat pump defrosting energy may be conserved considerably.

4.1 Operation

The setting of the heat pump controller rAM110A is executed by the Hoval customer service and does not need to be altered subsequently. The heat pump controller monitors the heat pump operation and si-gnals any malfunctions occuring.
