BENCHMARK
Benchmark places responsibilities on both manufacturers and
installers. The purpose is to ensure that customers are provided with the
correct equipment for their needs, that it is installed, commissioned and
serviced in accordance with the manufacturer's instructions by
competent persons and that it meets the requirements of the
appropriate Building Regulations. The Benchmark Checklist can be used
to demonstrate compliance with Building Regulations and should be
provided to the customer for future reference.
Installers are required to carry out installation, commissioning and
servicing work in accordance with the Benchmark Code of Practice
which is available from the Heating and Hotwater Industry Council who
manage and promote the scheme. Visit www.centralheating.co.uk for
more information.

PRE - INSTALLATION
3.1
GROUND SOURCE HEAT PUMP OPERATION
As the outside temperature gets colder, the heat demand of a house
increases and the output of an ground source heat pump will decrease.
Eventually it becomes so cold outside that the output of the heat pump
alone is not able to heat the building effectively. The Greestore range of
ground source heat pumps therefore allows for monoenergetic and
bivalent operation.
Monoenergetic means that in the event of very low external
temperatures a 3-stage electrical booster heater in the indoor unit will
automatically be activated to provide additional heat and keep the
building warm.
In bivalent operation a second heating appliance (e.g. gas or oil boiler) is
used to supplement the heat load.
3.2
SELECTION AND SIZING OF A HEAT PUMP
It is essential that heat pump systems are designed to operate efficiently
in order to meet the building heating needs and the expectations of the
customer. In order to achieve this, the following design activities must
be completed prior to installation:• Pre-design assessment - Determine the suitability of a heat pump
system for the building based on the customer requirements,
expectations and building type.
• Detailed design - Complete building heat loss calculations and
domestic hot water usage assessment.
• Specification - Select a suitable heat pump and system components
based on the detailed design. Calculate and communicate the
predicted energy use and running costs of the system to the
customer.
A suitable design methodology for the above is detailed in MIS3005, the
Microgeneration Certification Scheme (MCS) heat pump installer
standard. Worcester, Bosch Group recommended that this standard is
followed for heat pump systems. The standard covers the design,
installation and commissioning requirements to ensure that 100% of the
building heat loss can be met efficiently by the heat pump system. A heat
pump system must be designed to this standard to be eligible for
government financial incentives e.g Renewable Heat Incentive (RHI).
The Worcester Bosch Group design team offer a heat pump sizing
service which is MCS compliant. To request this service, download and
submit the form using the guidance notes from our website address:
www.worcester-bosch.co.uk/hp
3.3
HEAT LOSS
The total heat loss of the house is calculated from the addition of fabric
and ventilation heat losses.Fabric heat loss is the transmission of heat by
conduction through the building structure, i.e windows, walls, roof and
floor. Ventilation heat loss is heated air escaping from the house and
being replaced by cold air from outside.
3.3.1 CALCULATING THE HEAT LOSS OF THE HOUSE
It is essential to accurately calculate the heat loss of the house to ensure
correct sizing of the heat pump system. The heat loss is dependent on
the construction of the house, room sizes, external and internal design
temperatures and air change rates. The heat loss calculations should
satisfy the requirements of BS EN 12831.
3.3.2 ESTIMATING HEAT LOSS
Estimating the heat loss of the building is useful in determining the
suitability of a heat pump system. However, assumptions based on floor
area (e.g. 50 W/m² for new build etc.) and SAP (the governments
Standard Assessment Procedure) should not be used for the detailed
design and specification stage. It should be noted that the heat loss for
4
non standard houses i.e. houses with large areas of glazing, high
ceilings, log burners etc. or houses in exposed locations may deviate
significantly from any rules of thumb.
In existing properties, boilers are often oversized and should therefore
not be used to determine the actual heat requirements of the house.
However, estimates may be made on the basis of the existing energy
consumption of the space to be heated.
This installation manual does not cover all the necessary details to
calculate the heat loss. The information given here is provided to remind
the heating system designer and installer of the process and
considerations.
4
HEAT EMITTERS
Worcester, Bosch Group heat pumps are fitted with weather
compensation controls as standard. However, for a heat pump to
perform to its highest energy efficiency, the central heating emitter
circuit should be designed so that the flow temperature is as low as
possible.
As a guide, the system should be designed using the following maximum
flow temperatures;
• Underfloor heating: 35-40 °C
• Radiators: 45-50 °C
If underfloor heating has been installed, it is important to remember that
the underfloor system designer should have been informed that the heat
source will be from an air source heat pump. It is also important to
remember that radiators should have been correctly sized to work
effectively with lower flow temperatures.
A tool to aid installers and end users to understand the relevance of
building heat loss and heat emitter selection on heat pump performance,
has been created by the joint trade associations. The 'Heat Emitter
Guide' can be downloaded from the following website:
www.microgenerationcertification.org

The type plate is located on the roof plate of the heat pump. Information
about the heat pump's output, part number, serial number and date of
manufacture is stated there.
7.5
The outer cover plates should be removed to avoid damage if the heat
pump is transported without the supplied transport pallet.
The heat pump must not be stored at below zero temperatures.
POSITIONING THE HEAT PUMP
▶ The heat pump is placed indoors, on a level and stable surface that
withstands a weight of at least 500 kg.
▶ Adjust the rubber feet so the heat pump does not lean.
▶ The ambient temperature around the heat pump must be between
+10 °C and +35 °C.
▶ The installer should take sound propagation into consideration when
positioning the heat pump.
▶ The heat pump cylinder must be installed in line with The Building
Regulations 1991 (England & Wales) Requirements G3, L1 and
Regulation 7.
7.7
1. Position the heat pump on an even base. Adjust the height using the
adjustable feet.
2. Install the incoming and outgoing pipes for the heat pump, as well as
the expansion vessel.
3. Fit the filling unit, particle filters and valves.
4. Connect the heating unit to the heating system.
5. Install the outdoor sensor and possible room controllers.
6. Fill and vent the heating and collector systems before commissioning.
7. Carry out the external connections.
8. Connect the heating installation to the power supply.
9. Commission the heating installation by making all the necessary
settings on the control panel.
10. Check the heating installation after commissioning.
11. Top up more collector circuit fluid, if required.
7.9
CAN-BUS
CAUTION: Do not mix up the 12 V and CAN-BUS
connections!
The processors will be damaged beyond repair if 12 V is
connected to the CAN-BUS.
▶ Ensure that the four cables which are to be connected
to the contacts on the printed circuit boards are made
with their corresponding markings.
TRANSPORT AND STORAGE
The heat pump should always be transported and stored in an upright
position. However, the heat pump may be tilted temporarily, but must
not be laid down.
7.6
CHECKLIST
Each heat pump installation is unique. The following
checklist will give you a general description of how the
installation should be carried out.
INFORMATION ABOUT THE HEAT PUMP
6-11 Combi are heat pumps with integrated hot water cylinders.
7.2
7.8
The printed circuit boards in the heat pump, and accessories board if
applicable, are connected via the CAN-BUS communication line. The
CAN (Controller Area Network) is a system that facilitates
communication between microprocessor-based modules/printed
circuit boards.
A room controller is available as an accessory and must be connected by
a CAN-BUS cable.
Suitable cable for external laying is cable type LIYCY (TP) 2x2x0.5.
The cable must be twisted pair and screened. The screen must only be
earthed at one end and to the chassis.
Maximum cable length is 30 m.
The CAN-BUS cable must not be routed together with the mains cable
that carry 230 V or 400 V. The minimum clearance is 100 mm. Routing
of these cable together with the sensor cables is not permitted.
The connection between the circuit boards is by four wires, because the
12V-supply between the circuit boards must also be connected. The
circuit boards have markings for both the 12V and CAN-BUS
connections.
CHECKS BEFORE INSTALLATION
▶ Installation of the heat pump should be performed by a competent
person.
▶ Before the heat pump is commissioned, the heating system, hot water
cylinder and the collector circuit system, including the heat pump,
must be filled and vented.
▶ Check that all pipe connections are intact and have not shaken loose
during transportation.
▶ Wiring should be kept as short as possible to protect the system from
downtime, for example during a thunderstorm.

Term
No Term
A method for good ESD protection is a ground-connected bracelet when
handling electronics. This bracelet must be put on before opening the
screened metal bag/packaging or before exposing an installed board.
The bracelet must be worn until the circuit board is enclosed in its screen
packaging or closed electric box. Replaced, returned circuit boards must
be handled in the same way.

CAN-BUS termination
Terminated CAN-BUS
Non-terminated CAN-BUS
Switch Term marks the start and end of the CAN-BUS connection. The
display card (labelled with LCD on the wiring diagram) and the PEL card
in the heat pump must be terminated by switch Term (position ON).
If the CAN-BUS connected room controller is used it is terminated, and
Term on the PEL card in the heat pump must be set to not terminated
(position OFF).
When using the Multi Module (which is an accessory), the accessories
board in this module must be terminated, and Term on the PEL card in
the heat pump must be set to not terminated (position OFF).
We recommend that all printed circuit boards that are to be connected
to the CAN-BUS are installed first. When this is being done, switch Term
must be in the Term position. (ON position).
6 720 614 366-25.1I
Fig. 4
7.10.1 SETTING OF SWITCH TERM
When switch Term is in position ON, the loop is terminated. In position
ON, Term is placed at the middle position and covers the hole in the
board.
When switch Term is in position OFF, the loop is not terminated. In
position OFF, Term is placed at one of the side positions and the hole in
the board is not covered.

The heating system consists of one or more circuits. The heating system
is installed according to operating mode, depending on access to and
type. Settings for this are made by the installer
8.1
7.11 HANDLING CIRCUIT BOARDS
Circuit boards with control electronics are sensitive to discharges of
static electricity (ESD – ElectroStatic Discharge) when handled. To
prevent damaging the components, special care is therefore required
when handled.
CAUTION: Always wear a a ground-connected bracelet
when handling electronics.
HEATING, GENERAL
CIRCUITS FOR HEATING
• Circuit 1; the first circuit is included by default in the control unit and
is controlled by the installed flow sensor, possibly in combination with
an installed room controller.
• Circuit 2 (mixed); control of circuit 2 is also included by default in the
control unit and only needs to be supplemented with a mixing valve,
circulation pump and flow sensor and possibly with an additional
room controller.
• Circuits 3-4 (mixed); control of up to 2 additional circuits is optional.
Each circuit is then fitted with a Multi module, mixing valve, circulation
pump, flow sensor and possibly a room controller.
Circuits 2 through 4 cannot have a higher flow
temperature than circuit 1. This means that underfloor
heating on circuit 1 cannot be combined with radiators
on another circuit. Room temperature reduction for
circuit 1 can affect other circuits in some cases.
8.2
6 720 614 366-24.1I
Fig. 3
Bracelet
Damage is usually undetected, and a circuit board can operate correctly
during commissioning but show signs of problems later. Charged
objects may only be problematic if they are in close proximity to the
electronics. Keep a distance of at least one metre from expanded
polystyrene, protective plastic and other packaging, synthetic material
(e.g. fleeces) and similar before starting work.
6 720 806 768 (2013/02)
CONTROL METHODS FOR HEATING
• Outdoor sensor; a sensor is fitted on the north facing outside wall of
the house. The sensor sends signals to the control unit in the heat
pump. Control with an outdoor sensor means that the heat pump
automatically regulates the heating in the house depending on the
outdoor temperature. The customer determines the temperature of
the heating system in relation to the outdoor temperature by setting
the current room temperature in the control unit.
• Outdoor sensor and room controllers (one room controller per
circuit is possible); Control with outdoor sensor supplemented with
room controller(s) means that one (or several) controllers are
mounted in a central location inside the house. They are connected to
7
ENERGY METERING
the heat pump and provide the control unit with information about the
current room temperature. The signal affects the flow temperature.
For example, it falls when the room controller indicates a higher
temperature than the one set. Room controllers are used when factors
other than the outdoor temperature influence the indoor temperature
of the house. For example, this can be when a stove or fan-assisted
radiator is used in the house, or if the house is sensitive to the wind or
exposed to direct sunlight.
It is only the room where the room controller is located
that can influence the temperature of the relevant
heating circuit.
8.3
TIME CONTROL FOR HEATING
• Program control; the control unit offers four fixed and two individual
programs for clock setting of day/time.
• Holiday; the control unit has a program for holiday mode, which
means that during the selected period the room temperature changes
to a lower or higher level. The program also allows switching off hot
water production.
• External control; the control unit can make settings for external
control, which means that the preselected function is performed
when the control unit senses an input signal.
8.4
OPERATING MODES
• With electrical additional heat; the additional electrical heater is
used to supplement both DHW and CH when required temperature is
not fulfilled.
• With mixed additional heat (option); the additional boiler option is
used to supplement both DHW and CH when required temperature is
not fulfilled.
The Multi module accessory is required for mixed
additional heat and hot water electric heater.
9
ENERGY METERING
Energy metering in the heat pump is an approximation based on the sum
of the nominal emitted output during the relevant metering period. The
calculation requires for example that the heat pump is correctly
installed, and that the flow and  temperatures on the hot and cold sides
are adjusted as recommended. The value should therefore be regarded
as an estimate of the actual emitted output. The margin of error in the
calculation is normally put at 5-10%.
In addition, the energy output is affected by the outdoor temperature,
the settings for the thermostat and room controls and heat pump usage.
Ventilation, indoor temperature and hot water demand can play a
decisive role.

6 720 806 768-01.1I
Filling of sand or stone free soil approximately 100 mm around
the collector hose
Collector PE80/PE100 ø40 mm
The task of the collector hose is to convey the heat transfer fluid through
the ground to gain a few degrees of heat. The hose is a thin-walled plastic
hose of type PE80/PE100 quality, diameter 40 mm.
INSTALLATION AND BACKFILLING AROUND THE COLLECTOR HOSE
Installation of the collector and backfilling the soil around the collector
hose should follow applicable material and working descriptions and
regulations. It is important that the filling material does not contain
stones or other sharp objects that can damage the collector hose. Use
hose pliers, not a saw, when cutting the collector hose. Deburr the end
of the pipe internally and externally. It is important that no dirt or debris
enters the system. Dirt and debris can cause a blockage in the heat
pump.
MINIMUM PERMITTED BENDING RADIUS
Minimum permitted bend radius is 1 metre. If sharper bends are
required an elbow connector must be used. If the collector hose is damaged by too sharp a bend, it can be repaired by using a straight coupling.
MAXIMUM LENGTH OF THE COLLECTOR HOSE
The maximum length of the collector hose is based on the heat transfer
fluid pressure drop. A heat transfer fluid consisting of propylene glycol
and water is recommended.
The maximum collector hose lengths for heat pump
models are provided in the table. In situations where the
length of the collector hose needs to exceed the
permitted value, you can connect the hoses parallel.

Insulation
INSULATION OF PIPEWORK
All collector pipework should be insulated a minimum of 2 metres from
the property. Pipework should also be insulated where the flow and
return are closer than 800 mm to each other. Use Class O insulation, 19
mm thick.
Non-combustable pipe material must be used when
routing the pipes indoors.
CONNECTING THE COLLECTOR HOSE TO THE HEAT PUMP
It is important that the collector hose has been leak tested before it is
connected to the heat pump. The hose should be tested to 3-4 bar for a
minimum of 1 hour to ensure there are no leaks. The leak test can be performed using an air compressor. The collector is usually pressurised during the laying process.
The collector hose can be connected to the heat pump with one or more
circuits. In a multi-circuit system, the collector pipes are connected in
parallel as illustrated below. The parallel pipes are connected to two
manifolds. Each coil must have a shut off valve and a flow control valve.
The flow control valve is adjusted so that the flow rate is the same in each
coil. The coils should have the same length. If the length of the coils are
different, the control valves should be adjested so that each coil gets the
same flow. When adjusting the control valves, use the same difference in
percentage as the difference in the length of the coils.
21
INSTALLATION
After the manifolds and the flow control valves, the coils are connected
to a collecting pipe. A filling link, filter and the plastic expansion vessel
supplied with the heat pump are connected to the collecting pipe. A
pressure relief valve is connected to the outgoing pipe.
One circuit at a time is filled with heat transfer fluid. Keep the valves
closed in the other loops during the process.
• at least one pipe size larger than the nominal outlet size of the safety
device (larger sizes may be required if the equivalent hydraulic
resistance exceeds that of a straight pipe 9m long - refer to BS6700)
• terminate in a safe place where there is no risk to persons in the
vicinity of the discharge, and position safely from electrical devices
• have a vertical section of pipe at least 300mm long below the tundish
before any elbows or bends in the pipework.

13.3 COLLECTOR SYSTEM
INSTALLATION AND FILLING
Installation and filling of the collector system should comply with
applicable laws and current regulations, the MCS MIS 3005 standard
should be referred to for guidance. Soil used for refilling around the
collector hose must not contain stones or other sharp objects. Pressure
test the collector system before refilling to ensure that the system is
watertight.
When cutting the collector, it is important that no dirt or gravel enters the
system. This can cause blockages in the heat pump and damage
components.

EXPANSION VESSEL
It is important when installing the expansion vessel to position it at the
highest point in the circuit, preferably above the heat pump. If there is a
low ceiling making it impossible to fit the tank above the pump, it can be
positioned as illustrated in the figure to the left. It is important to install
the tank so that any air disappears upwards. If the tank is installed
incorrectly, the air will continue on in the circuit (Figure 21).

Chapter 11.2.1.
WARNING:
▶ Never block the safety valve outlet.
13.5 SITING THE APPLIANCE
Noise transfer to adjacent areas must be taken into consideration when
choosing a position for the heat pump ( Chapter 11.3 for sound
levels).
13.6 PIPEWORK PREPARATIONS
▶ Connection pipes for the collector system, heating system and
possible hot water should be installed in the premises to the heat
pump location.
▶ An expansion vessel, a safety group and a pressure gauge should be
mounted in the heating circuit.
▶ Mount the filling unit in a suitable place in the collector circuit.
NOTICE: Artificially softened water must not be used to
fill the central heating system.
NOTICE: If required the fitting of a magnetic particle
system filter can be fitted to the heating return pipe
work.
FLUSHING THE SYSTEM
▶ Fill the system with cold water and check for leaks.
▶ Open all drain cocks and drain the system.
▶ Close drain cocks and add a suitable flushing agent compatible with
aluminium at the correct strength for the system conditions in
accordance with the manufacturer‘s instructions.
The pH value of the system water must be less than 8 or the
appliance guarantee will be invalidated.
▶ Circulate the flushing agent before the heat pump is connected.
▶ Run the system at normal operating temperature as directed by the
manufacturer of the flushing agent.
▶ Drain and thoroughly flush the system to remove the flushing agent
and debris.
▶ It may be necessary to use a power flushing machine to aid the
cleansing procedure in some circumstances.
▶ Close the drain cocks and refill with fresh water and a suitable
inhibitor.
▶ Vent any air from the boiler and system.
▶ Clean the particle filter.
INHIBITOR/ANTIFREEZE
Add a suitable inhibitor or combined inhibitor/anti-freeze, if the system
is exposed to freezing conditions, to the heating system in accordance
with BS7593 and manufacturer‘s guidelines. In special cases where
increased protection is required Gylcol can be added with a maximum
concentration of 15%, Heat Pump performance will decrease.
WARNING: Sealing agents
▶ Normally the addition of sealing agents to the system
water is not permitted as this can cause problems
with deposits left in the heat exchanger.
▶ In cases where all attempts to find a micro leak have
failed, Worcester, Bosch Group supports the use of
Fernox F4 leak sealer.

13.12 FILLING THE HEATING SYSTEM
First flush the heating system. If the water cylinder is connected to the
system, it must be filled with clean water. The heating system is then
filled.
WARNING: Damage to the hot water cylinder can be
caused if filling is performed in the wrong order.
▶ Fill and pressurise the water cylinder before filling the
heating system.
13.12.1 FILLING THE HEATING SYSTEM WITH CLEAN WATER
Worcester Bosch recommends the fitting of an inline system filter to help
ensure that the heating system can perform at its optimum level.
▶ Set the pre-pressure for the expansion vessel in the premises
according to the heating unit's static height.
▶ Open the heating system's valves.
▶ Top up the heating water in the system and fill system to appropriate
operating pressure.
▶ Vent the heating system by opening the shut off valve. This may have
to be repeated a couple of times and is very important to ensure the
correct operation of your heat pump.
▶ Also bleed via the heating system's other bleed valves (e.g. radiators).
25
INSTALLATION
▶ Refill to the correct pressure. Normal pressure is 1.0 – 2.5 bar, but
depends on the expansion vessel's pre-pressure and the height of the
building.
▶ Shut the heating water filling valve when the correct pressure is
reached.
▶ Check all connections for leaks.
▶ Turn the valves on the filling unit so that they are in filling position (
Figure 27).
13.13 FILLING THE COLLECTOR SYSTEM
The collector system is filled with collector circuit fluid which must
guarantee antifreeze protection until –15 °C. We recommend a mixture
of water and propylene glycol.
Only glycol is permitted.
6 720 641 570-06.1I

FUNCTION CHECK
17.1 REFRIGERANT CIRCUIT
The refrigerant circuit may only be worked upon by
qualified and registered refrigerant engineers.
DANGER: Risk of toxic fumes!
The refrigerant circuit contains substances which, when
released or exposed to open fire, can form toxic fumes.
The fumes block the airways even at low concentrations.
▶ If the refrigerant circuit is not air-tight, the room must
be vacated immediately and properly aired.
When the heat pump starts and there are quick changes in temperature,
bubbles may become visible in the sight glass  Figure 44.

Maximum system pressure at highest heating water
temperature:
must not be exceeded (safety valve opens).
Table 21
▶ When the gauge is below 0.5 bar (in cold installation): Fill water until
the gauge shows approx 1 bar again.
▶ If there is a pressure drop: check the expansion vessel and heating
system for leaks.
17.4 OPERATING TEMPERATURES
Check the temperatures in the heat carrier and collector circuit after 10
minutes of operation:
• Temperature difference between heating system flow and return
approx. 7 ... 10 K.
• Temperature difference between collector circuit in and out approx. 2
... 5 K, recommendation: 2 ... 3 K.
When the temperature difference is too small:
▶ Reduce the speed of the corresponding circulation pump (G2 or G3)
in order to obtain a lower flow.
When the temperature difference is too great:
▶ Increase the speed of the corresponding circulation pump (G2) in
order to obtain a greater flow.

The heat curve forms the basis for set point value
calculation of the flow temperature. Most other
temperatures for heating that are set refer to room
temperature. These values are transformed by the
control unit into flow temperature values.

▶ Select type of heating system, Radiator or Underfloor.
The factory settings for the Radiator have a curve value (flow
temperature) of 22 °C at 20 °C an outdoor temperature, 37.4 °C at –
2.5 °C and 60 °C at -35 °C at an outdoor temperature (the high point of
the curve).
The heat curve constitutes the basis for the control unit's control of the
temperature on the heating water to the circuit and indicates how high it
needs to be in relation to the outdoor temperature. The control unit
increases the temperature of the heating water when the outdoor
temperature drops. The temperature of the heating water out to the
circuit, i.e. the flow temperature is measured by sensor T1 for circuit 1
(full name E11.T1) and sensor T1 for circuit 2 (full name E12.T1).
Each circuit is controlled by its own heat curve. The installer sets the
type of heating for each circuit, that is Radiator or Underfloor. The heat
curve for Underfloor has lower values because the floors do not tolerate
such high temperatures.
T1(˚C)
The factory settings for the Underfloor have a curve value (flow
temperature) of 22 °C at 20 °C outdoor temperature, 27.2 °C at -2.5°C
and 35 °C at -35 °C outdoor temperature.

Setting of heat curve
If the heat curve has been set too high, the display will
show the message Too high heat curve setting.
▶ Change the heat curve setting.
A heat curve is set for each circuit. If the room temperature is perceived
to be too high or too low in the circuit, it is preferable to adjust the curve.
The curve can be changed in different ways. The slope of the curve can
be changed by offsetting the flow temperature upwards or downwards
on the left-hand side (the value at outdoor temperature 20 °C, factory
value 22.0 °C) as well as the right-hand side (the value at outdoor
temperature -35 °C, factory setting 60.0 °C). In addition, the curve can
be affected by every 5th outdoor temperature degree.
The value at 0 °C is displayed above the curve's left-hand point, factory
value 35.7 °C.

SETTINGS
20.1.1 SET POINT VALUE
The heating circuit's set point value is the temperature of the flow that
the heat pump attempts to maintain. Sometimes, the measured actual
value fluctuates a bit upward and downward depending on changes in
the outdoor temperature or a large hot water demand.
The set point value specified by the customer/installer is
most often the room temperature, which is recalculated
by the control unit into a corresponding flow
temperature set point value. Under normal conditions, 1
K ( °C) in room temperature corresponds to approx. 3 K
( °C) in flow temperature.
The set point value is normally based on:
• Current curve value (the flow temperature at the current outdoor
temperature according to the applicable heat curve).
• Current curve influence through:
– Room sensor (room controller)
– Holiday
– Active program
– External control
SET POINT VALUE CALCULATION
The set point value for the heating circuit is the current curve value
adjusted with active curve influence, if any such exists.
Priority order for curve influence is:
operation; only hot water is produced. Automatic signifies change-over
at the set outdoor temperature.

• External set point value. The set point value is determined according
to input signal 0-10V where 1V is 10 °C and 10V is 80 °C (0V triggers
an alarm).
SET POINT VALUE LIMITATION
The calculated set point value is always checked against the permitted
temperature limits.
The applicable set point value T1 for Circuit 1 and the measured actual
value for T1 are used to activate and deactivate the heat demand.

In the event of change over between winter and summer
operation and vice versa, there is a certain delay to
prevent constant starting and stopping of the
compressor when the outdoor temperature oscillates
around the temperature limit.
Below the direct start limit, the control unit changes over
to winter operation without delay.
>> Maximum operating time for heating at hot water demand
The menu is not displayed if Block heating during hot water demand is
set to Yes ( Chapter 20.2).
The following applies to Circuit 2, 3...: When the actual value for the
mixed circuit's T1 is low in relation to the set point value, more heating
water is pumped into the circuit so as to maintain the set point value.
Factory setting

Highest value
If the flow temperature has been below the set point value for a certain
period of time, there is a heat demand and the compressor produces
heat before the indoor temperature is reduced significantly. This
happens until the flow temperature is a couple of degrees higher than
the set point value. (Or because Maximum operating time for heating
at hot water demand has passed.)

Table 114 Anti-seizure start time
▶ Set date and time for anti-seizure operation.
Anti-seizure mode ensures that components do not become seized
during periods of inactivity.
Anti-seizure mode operates differently in summer and in winter. This
enables the duration of the anti-seizure operation to be reduced.
Furthermore, during anti-seizure operation the entire system does not
need to be switched off in winter.
Anti-seizure mode in summer mode
Anti-seizure mode starts only if there is no other type of
demand. When there is a demand, the anti-seizure
operation waits for up to one hour for the demand to be
satisfied. Otherwise, the anti-seizure operation has to
wait until the next period.
Heat pump 1 runs first followed by heat pump 2, etc. 3way valves and circulation pumps are run for 1 minute
and mixing valves for the respective mixing valve's run
time + 10s. A pause of 30s is made between
components.
During anti-seizure mode, certain parts of the heating
system become hot for a short period of time, which is
completely normal.
The anti-seizure mode is not cancelled if a hot water
demand arises during the anti-seizure operation. The hot
water temperature can thereby fall. A suitable time for
anti-seizure operation is when the hot water
consumption is low, e.g., at night.
Anti-seizure mode in winter mode
In winter mode, anti-seizure operation only operates on
valves, mixers and pumps that normally do not operate
in winter mode (refers to accessories such as pool and
solar). Anti-seizure mode can occur during operation.

> Screed drying
Screed drying requires the installation of underfloor
heating coils under the floor tiles. Consult with screed
manufactories for information on maximum
temperatures and time required.
The screed drying function is used to expel humidity from the floor tiles
in newly-built houses. The drying program has the highest priority, i.e.,
all other functions than security functions and additional heat only are
disabled. All circuits contribute to the drying.
Screed drying takes place in three phases:
• Heating phase
• Phase with maximum temperature
• Cooling phase
▶ Specify the temperature difference which the heat pump will aim to
achieve. This is done by regulating the pump speed.
Heating and cooling are performed stepwise; each step continues for at
least a day. The phase with maximum temperature is considered to be
one step. There are 9 steps with the factory values: Heating phase in 4
steps (25 °C, 30 °C, 35 °C, 40 °C), maximum temperature (45 °C for
four days), cooling phase in 4 steps (40 °C, 35 °C, 30 °C, 25 °C).
It is possible to cancel a running program. On completion of the program,
the heat pump returns to normal operation.

21.1 SOFT STARTER
The soft starter has four different alarm causes, see table below.
Type 2 alarms are due to large voltage variations in the electricity grid.
Type 3 alarms indicate the existence of a fault in the compressor.
Types 4 and 5 alarms are there to protect the soft starter.
1) Stand-by means that the heat pump is running but no heating or hot water
demand exists.
The room controller alarm display function is referred to as an alarm
lamp in this chapter.
The room controller alarm lamp can be blocked.
The soft starter has normally 1 minute restart delay. The
restart delay is 5 minutes at an alarm.

described in the respective alarm description.
In most cases, warnings do not have to be acknowledged. The alarm
window disappears by itself once the warning cause has disappeared. It
is, however, possible to acknowledge the warning.
21.7 ALARM TIMER, ALARM MODE
In the event of an alarm that stops the compressor the control unit starts
a timer at 1h. If the fault does not recur additional heat may start when
the timer has counted down.
