FIGHTER 1310 HPAC is a system with the main com-

ponents: heat pump FIGHTER 1310 and exchange

module HPAC. FIGHTER 1310 has an integrated con-

trol computer with a display for control of the

heating/cooling, integrated circulation pumps and is

connected via the HPAC module to the external col-

lector and the building’s distribution system for heating

and cooling.

The heat exchange from the heat source (rock ,

ground or lake) takes place via a closed cooling medi-

um system where water mixed with antifreeze circu-

lates to the heat pump.

Ground water can also be used as a heat source how-

ever, this requires an intermediate heat exchanger

between the HPAC and the ground water.

Control

For the System manager

FIGHTER 1310 HPAC

Setting takes place by programming the Curve slope,

see the section Available information and settings on

the display, and by setting the Heating curve offset

using the Increase/reduce heat knob on the panel.

If the required room temperature is not obtained, read-

justment may be necessary.

PLEASE NOTE! Wait one day between settings so

that the temperatures have time to stabilise.

Readjusting the setting

Cold weather conditions

If the room temperature is too low, increase the

value for the heating curve by one step.

If the room temperature is too high, reduce the

value for the heating curve by one step.

Warm weather conditions

If the room temperature is too low, turn the

Increase/reduce heat knob one step clockwise.

If the room temperature is too high, turn the

Increase/reduce heat knob one step anticlockwise.

The indoor temperature depends on several factors.

Sunlight and heat emissions from people and house-

hold machines are normally sufficient to keep the

house warm during the warmer parts of the year.

When it gets colder outside, the heating system must

be started. The colder it is outside the warmer the out-

going temperature supply fan coil units must be. To

ensure sufficient cooling is obtained the outgoing tem-

perature to the fan coil units is lowered with a cooling

requirement. In FIGHTER 1310 HPAC this adaptation

is handled automatically by a control computer, which

must however be set with the right basic settings.

The heat pump is controlled by built-in sensors for

flow and return heat transfer fluid temperatures (col-

lector). Heat transfer fluid return temperatures can, if

so required, be limited to a minimum (e.g. for ground

water systems).

Control of the heating/cooling production is performed

based on the floating condensing principle, i.e. the

temperature level needed for heating at a specific out-

door temperature is produced guided by collected val-

ues from the outside and flow sensors. As an option,

room sensors can also be used to compensate for

deviations in room temperature.

General

Changing the room temperature manually

If you want to temporarily or permanently increase or

lower the indoor temperature in relation to the previ-

ous heat setting turn the Increase/reduce heat knob

clockwise or anticlockwise. One line approximately

represents a 1 degree change in the room tempera-

ture in the heating mode.

NOTE! An increase in the room temperature may be

inhibited by the radiator or floor heating thermostats, if

so these must be turned up.

Changing the room temperature

Setting heat/cooling

Control 7

For the System manager

The heat transfer pump is in operation when one of

the compressors is in operation.

When fitted with the Hot water control accessory and,

for instance, our hot water accumulator VPA, the

FIGHTER 1310 HPAC can be used for hot water pro-

duction.

The supply of heat to the building is controlled by the

control computer settings (curve slope and offset).

After adjustment the correct amount of heat for the

current outdoor temperature is supplied. The flow tem-

perature (

WW out

) from HPAC will vary around the

theoretical required value (value in brackets on the

control computer display). For subnormal tempera-

tures the computer calculates a deficit in the form of

degree minutes, which results in the acceleration of

heat production. The larger the subnormal tempera-

ture, the greater the heat production.

Heat production

Hot water production

Heat transfer fluid pump

With active cooling the compressor starts and the pro-

duced cooling circulates to the building’s distribution

system and the heat circulates out to the ground/rock

collector.

Active cooling.

Using the circulation pumps in FIGHTER 1310 fluid

from the ground/rock collector circulates through the

building’s distribution system and cools the building.

Cooling comes from the ground/rock collector.

Passive cooling

The cooling supply to the building is controlled by the

computer settings (curve gradient and offset). After

adjustment the correct amount of cooling for the cur-

rent outdoor temperature is supplied. The flow tem-

perature (

WW out

) from HPAC will vary around the

theoretical required value (value in brackets on the

control computer display). In the event of excess tem-

perature the control computer calculates a surplus in

the form of degrees-minutes, which means that the

greater the excess temperature that temporarily pre-

vails the more the connection of cooling production is

accelerated.

FIGHTER 1310 HPAC automatically switches to cool-

ing mode when the outdoor temperature exceeds the

set value in menu 3.

When the cooling requirement is large and passive

cooling is not sufficient active cooling is engaged at

the set limit value.

General points for the installation engineer 11

For the Installer

FIGHTER 1310 HPAC

In accordance with current norms, the heating/cooling

installation must undergo an installation check before

being used. The inspection must be carried out by a

suitably qualified person and should be documented.

The above applies to closed heating/cooling installa-

tions. If the heat pump or the cooling module are

replaced the installation must be inspected again.

The FIGHTER 1310 must be installed on a firm sur-

face, preferably a concrete floor or a concrete founda-

tion in a boiler room or a separate equipment room.

HPAC is installed suspended on the wall. Avoid

installing it in or adjacent to a sound-sensitive room.

Wherever the unit is located, any wall that backs on to

a bedroom should be fitted with sound insulation.

The FIGHTER 1310 must be transported and stored

upright and dry. HPAC should be transported and

stored horizontal and dry.

Transport and storage

Setting up the heat pump

Collectors

Inspection of the installation

The length of the collector hose varies depending on

the rock /ground conditions and on the distribution

system.

The maximum length of each loop is 500 metres.

The hose normally used is PEM hose 40 x 2.4 PN 6.3.

Collectors are always connected in parallel, with some

means of adjusting the flow.

Control of the heating/cooling production normal takes

place according to the floating regulation principle, i.e.

the temperature level needed for cooling/heating at a

specific outdoor temperature is produced with the help

of collected values from the outside and flow sensors.

As an option, room sensors can also be used to com-

pensate for deviations in room temperature.

Floating regulation

PLEASE NOTE!

This system solution means that the

heat transfer fluid will also circulate

through the heating system. Check

that all component parts are designed

for the heat transfer fluid in question.

For the Installer

Channel selection

Hold the Channel button down for about 7 seconds to

access the following menus.

By pressing the Channel button again you can browse

through the display settings below to find the informa-

tion you want.

If a value is programmable, this is denoted by a [P]

(Programmable) in front of the value.

If the next value cannot be set, pressing the Channel

button displays the next menu.

Setting/Control

The first step when changing a value is to press the

Increase button once. A cursor (line) then appears

under the value. The value can then be increased or

reduced using the Increase or Reduce buttons.

The electric output is controlled by the control comput-

er for optimum comfort. This calculates the deficit/sur-

plus on the flow temperature in the form of degree

minutes.

If, for example, the flow temperature has been 2

degrees lower than the calculated flow temperature for

10 minutes; 2 x 10 = 20 degree minutes is registered

by the computer. With the standard setting the number

of degree minutes should amount to -60 before the

compressor starts. The degree minutes will continue

to increase until the actual flow temperature is higher

than the set value. After that the accumulated degree

minutes will start to decrease and when zero is

reached the compressor will stop.

The length of the collector hose varies depending on

the rock /ground conditions and on the distribution

system.

When installing the collector hose ensure it rises con-

stantly towards the heat pump to avoid air pockets. If

this is not possible, install high points to vent the air.

The distribution system should be fitted with two pres-

sure expansion

vessels. The heat transfer fluid

side

should be pressurised to at least 0.5 bar.

All the system’s pipes are to be condensation insulated

except the pipes to the hot water heater.

If the temperature of the heat transfer system can fall

below 0 °C this must be protected against freezing

through the mixture of propylene glycol (NOTE! Not

ethanol). The mixing ratio should be approximately 25

% propylene glycol and the remainder water. As a

guideline for the volume calculation, use 1 litre of ready

mixed heat transfer fluid per metre of collector hose,

(for 40 x 2.4 PN 6.3 PEM hose).

The installation should be marked with the antifreeze

used.

Shut-off valves should be installed as close to the heat

pump as possible. Fit a particle filter to the incoming

pipe.

When connecting to an open ground water system,

due to the dirt and risk for freezing in the evaporator,

an intermediate frost protection circuit must be

installed. This requires an additional heat exchanger.

Pipe connections16

Pipe installation must be carried out in accordance

with current norms and directives. FIGHTER 1310

HPAC can only work up to a return temperature of

around 50°C and a flow temperature from the heat

pump of around 60°C. FIGHTER 1310 HPAC is not

equipped with shut-off valves so you have to install

them yourself outside the heat pump to facilitate future

service.

The fluid in the building’s distribution system is the

same as in the ground/rock collector.

FIGHTER 1310 HPAC

For the Installer

General

FIGHTER 1310 is connected to the HPAC and possi-

ble hot water heating

Pipe connections are made at the rear of the FIGHT-

ER 1310. Pipe connections are made at the bottom

and top of HPAC. The necessary safety equipment,

shutoff valves (fitted as close as possible to the heat

pump), and the particle filter and flexible hoses sup-

plied must be fitted.

When connecting to a system with thermostats on all

convectors, a relief valve must be fitted, or a number

of the thermostats must be removed to ensure suffi-

cient flow.

Pipe connection, the building’s

distribution system

Pipe connection, collector side

Condensation insulation

To avoid condensation, all pipes and other cold sur-

faces must be isolated with diffusion-proofed material.

Where the cooling demand is high, fan coil units with a

drip dish and drain connection are needed.

PLEASE NOTE!

This system solution means that the

heat transfer fluid will also circulate

through the heating system. Check

that all component parts are designed

for the heat transfer fluid in question.

A 60 Hz mains supply does not permit the heating medium pump to run at the highest capacity (upper curve in the

diagrams). A frequency

converter is needed to utilise the pumps’ entire capacity in a 60 Hz mains network.
