System diagram
F1245 consists of a heat pump, water heater, electrical
module, circulation pumps and a control system. F1245
is connected to the brine and heating medium circuits.
In the heat pump evaporator, the brine (water mixed
with anti-freeze, glycol or ethanol) releases its energy
to the refrigerant, which is vaporised in order to be
compressed in the compressor. The refrigerant, of
which the temperature has now been raised, is passed
to the condenser where it gives off its energy to the
heating medium circuit and, if necessary, to the water
heater. If there is a greater need for heating/hot water
than the compressor can provide there is an integrated
immersion heater.

Room sensor
Settings
F1245 is delivered with a room sensor supplied (BT50).
The room temperature sensor has up to three functions:
1. Show current room temperature in F1245's display.
2. Option of changing the room temperature in °C.
3. Makes it possible to change/stabilise the room
temperature.
Install the sensor in a neutral position where the set
temperature is required. A suitable location is on a free
inner wall in a hall approx. 1.5 m above the floor. It is
important that the sensor is not obstructed from
measuring the correct room temperature by being
located, for example, in a recess, between shelves, behind a curtain, above or close to a heat source, in a
draft from an external door or in direct sunlight. Closed
radiator thermostats can also cause problems.

The slope of the heating curve indicates how many
degrees the supply temperature is to be increased/reduced when the outdoor temperature drops/increases.
A steeper slope means a higher supply temperature at
a certain outdoor temperature.
The optimum slope depends on the climate conditions
in your location, if the house has radiators or under
floor heating and how well insulated the house is.
The heating curve is set when the heating installation
is installed, but may need adjusting later. Thereafter
the heating curve should not need further adjustment.
Caution
In the event of making fine adjustments for
the indoor temperature, the heat curve must
be offset up or down instead, this is done in

In the menu heating curve the so-called heating curve
for your house can be viewed. The task of the heating
curve is to give an even indoor temperature, regardless
of the outdoor temperature, and thereby energy efficient operation. It is from this heating curve that the
heat pump’s control computer determines the temperature of the water to the heating system, flow line
temperature, and therefore the indoor temperature.

5. Press the OK button to exit the setting.
If it is cold outdoors and the room temperature
is too low, increase the curve slope by one increment.
If it is cold outdoors and the room temperature

Basic values for the automatic heating control
The values stated on the map apply for the "heating
curve“ in menu 1.9.1.
႑ The first value applies for low temperature* radiator
systems. "temperature" (heating curve offset) in
menu 1.1 must be set to -2.
႑ The value in brackets refers to under floor heating
systems** installed in concrete floor structures.
႑ When the system is installed in a timber floor structure you can use the number before the brackets,
but this value must be reduced by two units. "temperature" (heating curve offset) in menu 1.1, set in these
cases to -1.
Caution
The map values are usually a good starting
point and concern an approximate room
temperature of 20 °C. The values can be adjusted later if necessary.
Examples of basic values selection:

Caution
Setting range: 5-70 °C
An increase in the room temperature can be
slowed by the thermostats for the radiators or
under floor heating. Therefore, open the
thermostat valves fully, except in those rooms
where a cooler temperature is required, e.g.
bedrooms.
Default value: 20 °C
A low temperature radiator system refers to a system
where the flow temperature needs to be 55 °C on the
coldest day.
** Under floor heating can be dimensioned very differently. The example above refers to a system where the
flow temperature must be approx 35-40 °C resp. 4550 °C on the coldest day.
Set the minimum temperature on the supply temperature to the climate system. This means that F1245
never calculates a temperature lower than that set
here.
If there is more than one climate system the setting
can be made separately for each system.
TIP
The value can be increased if you have, for example, a cellar that you always want to heat,

"compressor" is that which produces heating and hot
water for the accommodation. If "compressor" is
deselected, a symbol in the main menu on the heat
pump symbol is displayed. You cannot deselect "compressor" in manual mode.
"addition" is what helps the compressor to heat the
accommodation and/or the hot water when it cannot
manage the whole requirement alone.
"heating" means that you get heat in the accommodation. You can deselect the function when you do not
wish to have heating running.
"cooling" means that you get cooling in the accommodation in hot weather. You can deselect the function
when you do not wish to have the cooling running.
This alternative requires an accessory for cooling or if
the heat pump has a built in function for cooling.
Caution
If you deselect "addition" it may mean that
sufficient heating in the accommodation is not
achieved.
Set the vacation setting in advance and activate just before departure in order to maintain
the comfort.

Emptying the brine system
The siphon principle is used to empty the hot water
heater. This can be done either via the drain valve on
the incoming cold water pipe or by inserting a hose
into the cold water connection.
In order to service the brine system it may be easier to
drain the system first. This can be done in different
ways depending on what needs doing:
Draining the climate system
If, for example, the brine pump requires replacing or
the cooling module requires servicing, drain the brine
system by:
1. Close the shut-off valves to brine system (QM33)
and (QM34).
2. Connect a hose to the drain valve (QM2), place the
other opening of the hose in a container and open
the valve. A small amount of brine will flow into
the container.
3. Air must get into the system for the remaining
brine to run out. Do this by slightly slackening off
the connection at the shut-off valve (QM33) that
joins the heat pump with the cooling module.
In order to carry out service on the climate system, it
may be easier to drain the system first. This can be done
in different ways depending on what needs doing:
NOTE
There may be some hot water when draining
the heating medium side/climate system.
There is a risk of scalding.
Draining the heating medium side in the cooling

10 Disturbances in comfort
In most cases, the heat pump notes operational interference (operational interference can lead to disturbance in comfort) and indicates this with alarms and
shows action instructions in the display.
Troubleshooting
Info-menu
Basic actions
All the heat pump measurement values are gathered
under menu 3.1 in the heat pump menu system.
Looking through the values in this menu can often
simplify finding the fault source. See page 44 for more
information about menu 3.1.
Start by checking the following possible fault sources:
႑ The switch's (SF1) position.
႑ Group and main fuses of the accommodation.
႑ The property's earth circuit breaker.
႑ The heat pump's miniature circuit breaker (FA1).
႑ The heat pump's temperature limiter (FD1).
Manage alarm
/RZ SUHVVXUH DODUP
DODUP
LQIR DFWLRQ
If the operational interference is not shown in the display the following tips can be used:
Low hot water temperature or a lack of hot
water
႑ Closed or choked filling valve for the hot water
႑
UHVHW DODUP
DLG PRGH
In the event of an alarm, some kind of malfunction has
occurred, which is indicated by the status lamp changing from green continuously to red continuously. In
addition, an alarm bell appears in the information
window.
႑
႑
႑
Alarm
In the event of an alarm with a red status lamp a malfunction has occurred that the heat pump cannot
remedy itself. In the display, by turning the control knob
and pressing the OK button, you can see the type of
alarm it is and reset it. You can also choose to set the
heat pump to aid mode.
info / action Here you can read what the alarm means
and receive tips on what you can do to correct the
problem that caused the alarm.
reset alarm In most cases it is enough to select "reset
alarm" to correct the problem that caused the alarm.
If a green light illuminates after selecting "reset alarm"
the alarm has been remedied. If a red light is still visible
and a menu called ”alarm” is visible in the display, the
problem that caused the alarm remains. If the alarm
disappears and then returns, see the troubleshooting
section (page 64).
aid mode ”aid mode” is a type of emergency mode.
This means that the heat pump produces heat and/or
hot water despite there being some kind of problem.
This can mean that the heat pump's compressor is not
running. In this case the immersion heater produces
heat and/or hot water.
Caution
Selecting "aid mode” is not the same as correcting the problem that caused the alarm. The
status lamp will therefore continue to be red.
Low room temperature
႑ Closed thermostats in several rooms.
