【Installation methods】

Sanitary hot water, floor heating hot water and radiator heating hot water can all be get from the
indoor unit. With its inbuilt 1.5kW and 6kW electric heater, it ensures its heating capacity in cold
days and guarantees enough high temperature sanitary hot water.

By using a mixture water to mix high temperature sanitary hot water and medium temperature
sanitary hot water together, it ensures the ideal temperature of sanitary hot water, as well as
increases the amount of sanitary hot water.

【Installation

methods】

In the following pages you will find how to connect different system applications to this heat

pump, based on your system design. It is of course many ways to do this and it is impossible

tocover every possible system design in the market. We therefore use the following as our

standard applications that is safe, workable and that we recommend. Other applications and

settings for this is possible, but we leave this design to the installer, according to his knowledgeand

understanding of this specific unit menu and possible settings. It is some basic specifications

that applies for all system drawings which is highlighted, and that we ask you read carefully when

considering which system application to use.

-Sensor locations

-System with or without buffer tank

-Internal and external water pump

Sensor locations applies differently for different applications. As a general standard, please refer
to the following.

Sensor locations applies differently for different applications. As a general standard,

please refer to the following.

Without buffer tank: For more stable running of the heat pump, we suggest to place the

sensors on the return line and adjust the heating curve or cooling

temperature accordingly, to fit the normal Delta T for your heating/

cooling system.

With buffer tank(s): For more stable running of the heat pump, we suggest to place the

sensors in the buffer tank(s). As general standard, you should place the

heating sensor in the upper part and cooling sensor in the lower part.

Circulation pump: This unit has a built in circulation pump that makes it possible to

connect the unit directly to a heating system using the internal

circulation pump to circulate the water in the heating system. For bigger

system or in systems with too big pressure drop, the capacity of the

internal water pump is not enough, and a secondary water pump for the

system is required. An external water pump can be controlled by the

heat pump. Please refer to the following pages for different system

applications.

Observe! It is always the installer's responsibility to control that the pressure drop in the
heating system is not higher than the internal circulation pump can handle.

【1.Directly to heating system

】

【2.Directly to heating system

】

Observe! thermostatic controlled heating systems like floor heating,For radiators or fan

coils, an external bypass between turn and return manifold or thermostat valve, is

required.Minimum 28 mm copper piping or similar is required for heating system.

Observe! When external circulation pump is installed it must be connected to and powered

by the unit internal PCB

-No shunt valve

-No external circulation pump

-Internal bypass should be closed

-No shunt valve

-No external circulation pump for heating system installed

-Internal bypass should be closed -, and be partly in open position to balance the pressure

drop in the heating system.

. Thermostat controlled systems needs bypass in application 1.

【3.Connected directly to combined high and low temperature heating system.

】

【4.Connected to a buffer tank

】

Observe! Temperature reduction valve and separate circulation pump for low temperature

heating system is required.Minimum 28 mm copper piping or similar is required for heating

system.

-Close the internal bypass

-External circulation pump is required

-Internal bypass closed.

-Optional power to external circulation pump

-Parameter in the menu “Heating buffer tank” and/or “cooling buffer tank” in “Group 0” of

advanced setting should be set to “1” = “with buffer tank”.

Minimum 28 mm copper piping or similar is required for heating system.

【5.Connecting external hot water heater.

】

Observe! This set up requires that the external water heater have its own heater with

thermostat control and a mixing valve on the outlet to your hot water supply lines. The

units mixing valve is not required, but will increase the efficiency.Minimum 28 mm copper

piping or similar is required for heating system.

-Reconnect the thermostatic valve on top of the unit so “hot water” from the unit is put to the

“cold” side of the mixing valve.

-“Plug” the medium hot water outlet

-Connect a bypass from units “hot water” outlet to the “coldwater” inlet on the external water

heater. Set the internal electronic hot water heater thermostat to 0

This unit have internal 250-liter water tank preserved for hot water for a normal family usage.

Some households use more hot water than normal, due to for example big bathtubs or the

number of family members. If so, we recommend connecting an extra water heater tank in series

with the heat pump hot water tank.

Heat pump will now either mix between heat pump and electric water heater or preheat the hot

water to the external water heater.

【6.Connecting an existing external boiler or other heating device as back up.

】

Observe! The installer must fulfill the installation and system design in accordance to both

functionality of heat pump and heating system, and in accordance to, local laws and

installation standards and regulations. A separate shunt valve with external controller is

required to mix in the heat from the boiler.Minimum 28 mm copper piping or similar is

required for heating system.

This unit is designed to be a total heating source for a normal house within a normal outdoor

temperature range. The heat pump has its own output and an additional built in 2 step 6 kW

(3+3 kW) electric heater for taking care of the peak load of your heating system the coldest days,

or if heat pump have functional failure. In some cases, the local lowest ambient temperatures or

the maximum heat load in the building is higher than the available output from the unit. For

some houses, the available electric power may not be enough to cover the input to the built in

electric heater. In these cases, you can connect an existing gas, oil or pellets burner to the system.

It is several ways to do this, so please use the below drawings as a template for how to design the

system. The heat pump can also control the start and stop of two external boiler or heating device

based on heat demand and prioritize between them, but external boiler or heating device always

needs to have its own internal temperature control and safety device.

【6.1Control start of external boiler

】

6.1.1: If the available electricity is enough to over the power consumption of heat pump

only only:

Observe! HTH only valid when parameter setting C7 in Advanced Setting Group C to 1

(default factory setting).Minimum 28 mm copper piping or similar is required for heating

system.

HTS: 3kW auxiliary heater valid for both heating and domestic hot water operation

HTH: 3kW back-up heater for heating operation only

Default setting: HTH has higher priority than HTS, which means, HTS will be activated only

after HTH is activated, if heating capacity is not enough. Installer can choose from following

ways to add a boiler to the system:

-Leave the 3kW heater connected to HTS and HTH not connected with power supply.

-have boiler parallel connected to HTH port, so boiler will be activated if unit capacity is not

enough to cover the house heating demand.
