Functioning principle of heat

pump system

Heat pumps operate on the principle of a refrigerator:

the same technology, only with the opposite eect. The

refrigerator extracts heat from foods, which is released

into the room through ns on the back.

The heat pump extracts heat from our environment:

air, earth or ground water. The extracted heat is con-

ditioned in the unit and supplied to the heating water.

Even when it is extremely cold outside, the heat pump

draws enough heat to heat a house.

Example: drawing of a brine/water heat pump with oor

heating:

4⁄4= usable energy

ca. 3⁄4= environmental energy

ca. 1⁄4= external

electrical energy

Area of utilisation

Taking into consideration the ambient conditions, limits

of application and the applicable regulations, every he-

at pump can be utilized in new or existing heating sys-

tems.

Overview „Technical data / scope of delivery“.

Heat quantity recording

In addition to proof of the unit‘s eciency, heating

legislation also requires heat quantity recording

(referred to as WME in this manual). The WME is

mandatory with air/water heat pumps. With brine/

water and water/water heat pumps, a WME is only

required when the feed temperature is ≥ 35 °C. The WME

must record the total warm energy release (heating

and hot water) in the building. In heat pumps with heat

quantity recording, the analysis is conducted by the

regulator. The regulator displays the thermal energy

that is exchanged from the heating system in kWh.

Operation

Your decision to purchase a heat pump or a heat pump

system is a long-term contribution to protecting the

environment through low emissions and reduced

primary energy use.

You can operate and control the heat pump system

with the control element of the heating and heat pump

regulator.

NOTICE.

Make sure that the control settings are correct.

Operating manual of the heating and heat

pump regulator.

To ensure that your heat pump or heat pump system

operates eciently and ecologically, the following are

especially important:

€ENERGY SAVING TIP

Avoid unnecessarily high ow temperatures.

A lower ow temperature on the hot water side

increases the eciency of the system.

€ENERGY SAVING TIP

When letting in fresh air, do not leave windows

open for an extended period, thus saving en-

ergy and reducing your heating costs.

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 surfaces and could also damage the

technical components of the unit.

Maintenance of the unit

The cooling circuit of the heat pump requires no regu-

lar maintenance.

According to EU regulation (EC) 517/2014, leak

inspections and maintenance of a log book are required

by law for certain heat pumps!

Log book for heat pumps, Section “Information

on use of the log book”.

The components of the heating circuit and the heat

source (valves, expansion vessels, circulating pumps, l-

ters, dirt traps) should be inspected as well as cleaned as

needed - at the very least annually - by a qualied hea-

ting or cooling system technician.

It is a good idea to have a maintenance contract with

a specialist company. The company will conduct the

required maintenance at regular intervals.

ATTENTION

Check regularly to ensure that the condensate

can drain out of the unit unobstructed. To this

end, regularly check the condensate pan in the

unit and the condensate drain to ensure that

they are clean / free from obstructions and clean

as needed.

CLEANING AND FLUSHING OF UNIT COMPONENTS

CAUTION!

Unit components may be cleaned and

ushed only by customer service personnel

authorised by the manufacturer. Use only

liquids recommended by the manufacturer.

Flushing of the liqueer with chemical

cleaning agents must be followed by

neutralisation of residue and intensive

rinsing with water. Always observe the

technical data of the manufacturer of the

heat exchanger.

Malfunctions

In the event of a malfunction, you can detect the cause

of the malfunction via the diagnostic program of the he-

ating and heat pump regulator.

Operating manual of the heating and heat

pump regulator.

DANGER!

Service and repair work on the components

of the unit may be performed only by custo-

mer service personnel authorised by the ma-

nufacturer.
