data sheet near to the units.
Identification of notes
1.2
This section provides an overview of all important
safety aspects for proper protection of people and
safe and fault-free operation.The instructions and
safety notes contained within this manual must be
observed in order to prevent accidents, personal
injury and material damage.
Notes attached directly to the units must be
observed in their entirety and be kept in a fully
legible condition.
Safety notes in this manual are indicated by symbols. Safety notes are introduced with signal words
which help to highlight the magnitude of the danger
in question.

vided for this purpose at the factory. The units
may only be secured or mounted on stable
structures, walls or floors.
n Mobile units must be set up securely on suit-
able surfaces and in an upright position. Stationary units must be permanently installed for
operation.
n The units and components should not be oper-
ated in areas where there is a heightened risk
of damage. Observe the minimum clearances.
Under no circumstances should the threshold
values specified in the technical data be exceeded.

Economical and environmentally-conscious
heating
The burning of fossil-based energy sources in
order to generate power creates severe consequences for the environment. A high percentage of
fossil fuels is also problematic due to the limited
resources of oil and gas and the price increases
resulting from this. For this reason, many people
today are thinking both economically and environmentally-consciously in terms of heating. The
application of heat pump technology enables both
of these concepts to be combined. It makes use of
the energy which is permanently available in the
air, water and soil and converts it into usable
heating energy by means of inputting electrical
energy. Yet in order to generate heat equivalent to
Heat source
There are essentially three heat sources that heat
pumps can derive energy from. air, soil and
groundwater. Air heat pumps have the advantage
that air as a source heat is available everywhere in
unlimited quantities that can be used free of
charge. A disadvantage is that the outside air is at
its coldest when the heat requirement is greatest.
Brine heat pumps extract energy from the soil. This
is undertaken in serpentine pipe networks which
are laid approx. 1m deep or placed by means of
drilling. The disadvantage is the large space
requirements for the serpentine pipe networks or
the high cost of drilling. A long-term cooling of
the soil is also a possibility.

Water heat pumps require two wells in order to
obtain heat from the groundwater, one supply well
and one dry well. The development of this source
is not possible everywhere, it is expensive and
requires planning permission.
Function of the heat pump
A heat pump is a device which makes use of a
working medium to absorb ambient heat under low
temperatures and transports this heat to a place
where it can be of use for heating purposes. Heat
pumps work according to the same principles as a
refrigerator. The difference is that heat, the byproduct of the refrigerator, is the goal of the heat
pump.
The main components of the cooling circuit consist
of an evaporator, a compressor, a condenser and
an expansion valve. In a finned evaporator,
the refrigerant evaporates both because of lower
pressure and because of lower heat-source temperatures through absorption of energy from the
environment. In the compressor, the refrigerant is
brought to a higher pressure and temperature by
the application of electrical energy. Next, the hot
refrigerant gas reaches the condenser, a plate
heat-exchanger. Here the hot gas condenses,
transferring heat to the heating system. The liquefied refrigerant then expands and cools in a flow
regulator, the expansion valve. Then the refrigerant flows into the evaporator once more and the
cycle is complete.
For control, a heat-pump manager is included
which ensures the independent operation of all
safety devices. The water-circulation system of the
Series CMF consists of a charging pump, plate
heat-exchangers, dirt traps, a manometer, fill- and
drain valves, an automatic air-bleeder and flow
monitor.
The CMT series has, in addition, a 3-way switching
valve and a buffer storage.
Wall- and floor consoles, condensate pans, condensate-pan heating, a 3-way switching valve, a
bypass valve and other sensors are available as
accessories.

Heat pump modes
Heat pumps can work in various operating modes.
Monovalent
The heat pump the only source of heat for a
building all year round. This mode is particularly
suitable for heating plants with low supply-water
temperatures and is primarily used in combination
with brine/water and water/water heat pumps.
Single energy source
The heat pump has an E-heater to handle peak
loads. The heat pump covers the majority of the
required heating power. Occasionally, when it is
extremely cold outside, an electrical boosterheating system switches on as required in order to
support the heat pump.
Bivalent parallel
The heat pump provides the entire heating energy
down to a predetermined outdoor temperature. If
the temperature drops below this value, a second
heat source switches on to support the heat pump.
There is a distinction to be made here between
alternative operation with oil- or gas heat and
regenerative operations with solar energy or
wood-fired heating. This mode is possible for all
heating systems.
Layout
A precise calculation of the building's heating load
according to EN 12831 is required for the design
and dimensioning of a heating system. However,
approximate requirements can be determined
based on the year of construction and the type of
building. The table shows the approximate specific
heating loads for a number of building types. The
required heating system output can be calculated
by multiplying the area to be heated with the given
values
For a precise calculation, various factors must be
considered. The transmission-heat requirement,
the infiltration heat-loss and an allowance for water
heating comprise the total heating output which the
heating system must provide.
The total area of the floor surfaces, exterior wall
windows, doors and roofing is required in order to
determine the transmission heat requirement. In
addition, information about the materials used in
the building is required, as these lead to extremely
varied thermal transmission coefficients (the so
called K value). Also required are the room temperature and the standard outdoor temperature,
that is, the lowest outdoor-temperature on average
that will occur during the year. The equation for
calculating the transmission-heat requirement is
Q=A x U x (tR-tA) and must be calculated sepa-
rately for all room-enclosure surfaces.
The infiltration heat requirement takes into consideration how often the heated room air is
exchanged for cold external air. The room volume
(V), the air exchange frequency (n) and the specific heat capacity (c) of the air is also required in
addition to the room temperature and average low
temperature. The equation is: Q=V x n x c (tR-tA).
An approximate allowance for heating water - per
person according to VDI 2067: 0.2 kW
Example
A residential home comprised of 115 m² livingspace and a heat requirement of 100 W/m² has
been selected for the example design. A total of
five persons live in the house. The heat load
amount to 11.5 kW. Adding a drinking water allowance of 0.2 kW results in a required heat capacity
of 12.5 kW. Depending on the power company, an
additional charge must then be made in order to
factor in the service time-out period. The rating and
determination of the heat pump's balance-point
temperature derives graphically from the heat
pump's temperature-specification heat-output diagram. (In the example, 35 °C for a floor heatingsystem). Next, the heat load for the standard outdoor temperature (the lowest temperature of the
year locally) and the heat threshold are marked on
the graph (Fig. 27). The outdoor-temperaturedependent heating requirement, simplified here as
a straight-line relationship between heat-load and
the start of the heating season, is recorded in the
graph of heat-load curves. The intersection of the
two straight lines with the rated heat-load curve is
plotted on the X axis, where the balance-point temperature is read. (in the example, ca.-3°C) The
least load of the 2nd heat source is the difference
between heat load and the heat pump's maximum
heat output on these days. (In the example, the
capacity necessary to cover peak loads is ca. 4
kW.)

Characteristics of REMKO inverter heat pumps
Outdoor air as a heat source
An air/water heat pump absorbs energy from the
outdoor air as its heat source and transmits this to
the heating system. They have the following
advantages over brine/water and water/water heat
pump systems:
n Can be used everywhere Air is available every-
where in unlimited quantities. For example, no
wells are required.
n No excavation required. No large areas are
required for soil collectors.
n Economical. Expensive drilling is not required.
n Excellent value for money and simple installa-
tion.
n Particularly suitable for low-energy houses with
low inlet temperatures.
n Ideal for bivalent operation, in order to save
energy.

Split AC unit
The Remko inverter heat pump is a so called split
AC unit. This means that it consists of an outdoor
unit and an indoor unit, both of which are connected via refrigerant-carrying copper pipes. Thus
there are no water-carrying pipes laid from the
indoors to outdoors which need to be made frost
proof. The outdoor unit contains only the condenser, the evaporator and the expansion valve.
This means that the outdoor unit is considerably
smaller. The indoor module contains the system's
condenser and the connections for the heating network.
REMKO inverter technology
The heat pump's condenser is equipped with a
requirement-dependent speed control system. The
power control on conventional heat pumps provides only two states, either ON (full output) or
OFF (no output). The heat pump turns on below a
specified temperature and turns off when this temperature is reached. This kind of heat regulation is
very inefficient. Heat regulation in the Remko
inverter heat pump is modulated to the actual
need. The electronics system has an integrated
frequency-converter which serves to modify the
condenser speed and the speed of the blower as
required. The condenser works at a higher speed
when under full load than under partial load. The
lower speeds ensure a longer operational lifetime
for the components, improved coefficient of performance and lower noise. Lower speeds also
result in lower energy consumption (electricity) and
longer service life. I.e.: inverter heat-pumps will run
practically throughout the heating season. In all,
the highest efficiency possible.

REMKO CMF/CMT
Thanks to innovative inverter technology, this
heat pump will almost always operate by
adapting its heating capacity to the actual
requirements of the heating season, and will in
fact turn itself off when heat is no longer
needed. The same applies in the opposite
direction with cooling.
Defrost by circulation reversal
At temperatures below about +5°C, humidity
freezes in the evaporator (outdoor module) and an
ice layer can form which reduces heat transfer
from the air to the refrigerant and to the air stream.
This layer of ice must be removed. A four-way
valve serves to reverse the refrigerant circuit, so
that the hot gas from the compressor flows through
the original evaporator and the ice that has formed
there can melt. The defrost process is not initiated
after a predetermined time; rather it is carried out
as required in order to save energy.
Cooling mode
Because of circuit reversal, cooling is also possible. In cooling mode, the components of the
refrigeration circuit are used to produce cold water
with which heat can be extracted from a building.
This can be accomplished with dynamic cooling or
passive cooling.
Under dynamic cooling the refrigerating capacity
is actively transferred to the indoor air. This is
undertaken by means of water-based REMKO fan
convectors. In doing so, it is desirable that the inlet
temperatures are under the dewpoint, in order to
transfer a higher refrigerating capacity and to
dehumidify the indoor air.
Passive cooling refers to the absorption of heat
via cooled floors, walls or ceiling surfaces. In doing
so, water-carrying pipes make the structural sections into thermically effective heat exchangers. In
order to achieve this, the refrigerant temperature
has to lie above the dew point, in order to avoid the
formation of condensation. Dewpoint monitoring is
required for this purpose.
We recommend dynamic cooling with fan convectors, in order to achieve increased thermal performance and in order to dehumidify the air on
muggy summer days. The advantage here is that
dewpoint monitoring is not required.
The comfort zone in the illustration below shows
which values for temperature and humidity are
considered comfortable for people. This range
should ideally be met when heating or air-conditioning buildings.

3.2 CMF series
We offer two different indoor-unit designs. The
wall-mounted CMF series is equipped with a circulation pump and a safety module on the water side.
Furthermore, an electrical booster heater can be
incorporated as an option. The CMF series was
constructed for the addition of several heat
sources (bivalent installations or systems with
solar-heating equipment). External buffer storage
is always required, its size depending on the type
and the power of the second heat source. On the
one hand, the buffer storage prevents short runtimes for the heat pump and on the other hand,
that sufficient defrosting energy is available.
3.3 CMT series
In addition, the indoor module of the CMT series is
fitted with a hot-water buffer storage. An electric
booster heater with a max. output of 9 kW is
standard. The hot-water buffer-storage has a
capacity of 160 litres and is integrated as a
hydraulic switch. As a result, the CMT series is the
ideal equipment when the heat pump is intended
as the sole heat source (single energy-source operation). A heating circuit pump must be mounted
on site.

9,52 mm) and 5/8" (= 15,88 mm). A two-wire control cable has to be laid between the two modules.
Both the indoor and outdoor modules require a
separate power supply.
WARNING!
All electric lines are in accordance VDE regulations to dimension and to lay.
4.2 General mountig instructions
DANGER!
The installation of refrigerant equipment may
be undertaken only by trained specialist personnel!
DANGER!
All electrical installation work must be done by
an electrician.
n These instructions are to be observed when
installing the entire system.
n The device should be delivered as near as
possible to the site of installation in its original
packaging in order to avoid transport damage.
n The device is to be checked for visible signs of
transport damage. Possible defects must be
reported immediately to contract partners and
the forwarding agent.
n Suitable sites for installation are to be selected
with regard to machinery noise and the set-up
process.
n The shut-off valves for the refrigerant lines may
only be opened immediately before commissioning of the system.
n The exterior components are pre-filled with
refrigerant up to a distance of 30 meters from
the interior component. If the basic length of
the refrigerant line exceeds 30 metres, add
refrigerant.
n Establish all electrical connections in accord-
ance with the relevant DIN and VDE standards.
n The electrical power cables must be fastened
to the electrical terminals in the proper manner.
Otherwise there is a risk of fire.
n See that neither refrigerant or pipes that carry
water pass through living- or sleeping areas.
Wall breakthroughs
n A wall opening of at least 70 mm diameter and
10 mm slope from the inside to the outside
must be created.
n To prevent damage, the interior of the wall
opening should be padded or, for example,
lined with PVC pipe (see figure).
n After installation has been completed, use a
suitable sealing compound to close off the wall
breakthrough under observation of fire protection regulations (responsibility of customer).
NOTICE!
Open refrigerant pipes must be protected
against the introduction of moisture by means
of suitable caps or adhesive strips Refrigerant
pipes may not be kinked or compressed.
Refrigerant pipes may only be cut to length
with a suitable pipe cutter (use no hacksaws or
the like).

4.4 Installation, mounting outdoor module
Outdoor module installation location
n The device may be attached only to a load-
bearing structure or wall. Ensure that the outdoor module is installed only vertically. The
installation site should be well ventilated.
n To minimise noise, install floor consoles with
vibration dampers and a considerable distance
from acoustically-reflective walls to minimise
noise.
n The minimum clearances specified on the next
page should be maintained when carrying out
the installation. These minimum distances
serve to ensure unrestricted air intake and
exhaust. Additionally, there must be adequate
space available for installation, maintenance
and repair.
n If the outdoor module is erected in an area of
strong winds, then the device must be protected against them (Fig. 37). The snow line is
to be observed during installation (
n The outdoor module must always be installed
on vibration dampers. Vibration dampers prevent the transmission of vibrations through the
floor or walls.
n A heated, condensate catch-pan ensures that
condensation from the pan can drain off.
Ensure that the condensate is prevented from
freezing so that it can drain off (gravel,
drainage). The Water Ecology Act is to be
observed.
n If there is insufficient space under the device
for the refrigerant lines, then the pre-cut
recesses can be removed from the lateral
enclosure-panel and the pipes guided through
these openings.
n During installation, add about 20 cm to the
expected snow depth to guarantee unimpeded
intake and exhaust of outdoor air year round
(Fig. 38).
n The installation site of the outdoor module
should be agreed together with the operator
primarily so that operating noise is minimised
and not in terms of “short routes”. Thanks to
the split-design technology there are a great
deal of different installation options with almost
identical efficiency available.

Condensate draining and ensured discharge
Condensate connection
If the temperature falls below the dew point, condensation will form on the finned condenser during
heating operation.
A condensate drip pan should be installed on the
underside of the unit to drain any condensate.
n The condensate drain pipe to be installed on-
site must be installed with a in cline of at least
2 % for good drainage. If necessary, fit vapour
density insulation.
n When operating the system at outdoor temper-
atures below 4 °C, care must be taken that the
condensate line is frost protected. The lower
part of the housing and condensate pan are to
be kept frost free in order to ensure permanent
drainage of the condensate. If necessary, fit
supplementary pipe heating.
n After completed installation, check that the
condensate drainage is unobstructed and
ensure that the line is leak tight.
40
Ensured discharge in the event of leakage
With the REMKO oil separator OA 2.2, the below
listed requirements of local regulations and laws
are met.
NOTICE!
Local regulations or environmental laws, for
example the German Water Resource Law
(WHG), can require suitable precautions to
protect against uncontrolled draining in case of
leakage to provide for safe disposal of
escaping refrigerator oil or hazardous media.

5 Hydraulic connection
A separate interpretation of nominal flow rate
must be made for every system (see technical
data).
n We recommend installing a buffer storage unit
as a hydraulic switch for hydraulically isolation
of the heating circuit.
n Make a pipe-network calculation before instal-
ling the heat pump. After installing the heat
pump, it is necessary to perform a hydraulic
balancing of the heating circuit.
n Protect floor heating systems against exces-
sively high inlet temperatures.
n Do not reduce pipe diameters for the supply
and return connections to the heat pump
before connecting a buffer storage-unit.
n Plan for air bleed valves and drain-off taps at
appropriate places.
n Flush the the system's entire pipe network
before connecting the heat pump.
n One or, where necessary, several expansion
tanks must be designed for the entire hydraulic
system.
n The system pressure of the entire pipe network
is to be matched to the hydraulic system and
must be checked when the heat pump is
turned off. Also update the static-pressure form
supplied with the heat pump.
n As delivered, the safety assembly consists of a
manometer, air bleeder and safety valve. It is
to be mounted to the pipe connection provided
on the indoor unit.

Turning the thermometer heads serves to close
or open the stop valves! The dial be brought
into the desired position.
n Install the dirt traps delivered with the unit out-
side the heat pump in the return line. Ensure
that the dirt trap remains accessible for inspection.
n Be sure to position one gate valve upstream
and another downstream of the dirt traps. This
ensures that the dirt traps can be checked at
any time without loosing water.
n The dirt traps must be checked during every
service of the system.
n Additionally, a hand-operated bleeder is
installed on the heat pump for additional
bleeding.
n All visible metallic surfaces must be addition-
ally insulated.
n Cooling mode via the heating circuit requires a
completely vapour diffusion tight insulation
along the entire length of the pipework.
n All outgoing heating circuits, including the con-
nections for water heating, are to be secured
against circulating water by means of check
valves.
n Before being placed in service, the system
must be thoroughly flushed. Conduct a seal
test and perform a thorough bleeding of both
the indoor unit and the entire system - repeatedly, if necessary.
Actual schemas for hydraulic integration can be
found on the internet at www.remko.de
n The heat pump requires a constant, minimum
standing-water volume of ca. 10 litres per kW
of heating output to guarantee power for
defrosting and to assure a minimum running
time. Buffer storage unit.

6 Corrosion protection
Oxygen always plays a role if metal materials in a heating system corrode. pH values and the salt content
also play a major role. The challenge: A licenced plumber who would like to be able to guarantee his customers a hot water heating system not at risk of corrosion from oxygen - without the use of chemicals - must
pay attention to the following:
n Correct system design by the heating contractor/planner and
n subject to the installed materials: filling the heating system with demineralised softwater or fully deionised
water, checking the pH value after 8 to 12 weeks.
See the following table for the requirements in accordance with VDI 2035 Part 1 with regard to total hardness.
Total hardness [°dH] subject to the specific system volume
Overall output in kW <20 l/kW ³20 l/kW and <50 l/kW ³50 l/kW
to 50 kW £16,8 °dH £11,2 °dH £0,11 °dH
The following table provides the allowed oxygen content in connection with the salt content.

Electrical conductivity
at 25°C
Oxygen content mg/l < 0,1 < 0,02
pH value at 25°C 8,2 - 10,0 *)
*) For aluminium and aluminium alloys the pH value range is limited: the pH value at 25°C is 8.2-8.5 (max.
9.0 for aluminium alloys)
In low-salt water and the correct pH for a short time even to oxygen concentrations up 0.5 mg / l are
tolerated.
Water treatment with chemicals
Adding chemicals to treat water should only be
done as an exception. VDI 2035 Part 2 requires
explicitly under Point 8.4.1 that all water treatment
be explained and documented in the system log
book. This has reasons:
μS/cm < 100 100-1500
n The improper use of chemicals often leads to
the failure of elastomer materials
n To blockages and deposits because of sludge
formation
n To defective floating seals in pumps
n To the formation of biofilm which can cause
microbial influenced corrosion or significantly
impair heat transfer.

erant lines
7.1 Connection of refrigerant lines
n The outdoor- and the indoor units are con-
nected with two copper pipes of refrigerator
quality having the dimensions 3/8" = 9,52 mm
and 5/8" = 15,88 mm (REMKO special accessory).
n Observe the permitted bending radius for the
refrigerant pipes during installation in order to
prevent kinks. Never bend a pipe twice in the
same place in order to prevent embrittlement
or crack formation.
n Assure suitable fastening and insulation when
laying the refrigerant pipes.
n The copper pipes are to be flared to make the
connections to the units. In doing so, check
that the flare has the correct shape and suitable union nuts. (Fig. 44
to Fig. 46).

n Remove the cover panel from the outdoor unit
if necessary. It may be necessary to remove
the pre-cut bushings.
n Take off the factory-fitted protective caps. You
can use the union nuts for additional mounting.
Make sure to slide the union nuts onto the pipe
before it is flared.
n Make connections to the device by hand ini-
tially, in order to ensure a good fit. Later,
tighten the joints with two open-end wrenches
Use one wrench to resist the rotation of the
other (Fig. 47).
NOTICE!
Use only tools which are approved for use in
an HVAC environment. (z. B.: bending pliers,
pipe/tubing cutters, de-burrers and flaring
tools). Do not cut refrigerant pipes with a saw.
NOTICE!
All work must be carried out in a way that prevents dirt, particles, water etc. from entering,
refrigerant lines!

Tightening torque
Outdoor units may be delivered with nuts suitable for joining flanges.
7.2 Commissioning the refrigeration system
Leak testing
Once all the connections have been made, the
pressure gauge station is attached to the Schrader
valve as follows (if fitted):
blue = large valve = suction pressure
Once the connection has been made successfully,
the leak test is carried out with dry nitrogen. The
leak test involves spraying a leak detection spray
onto the connections. If bubbles are visible, the
connections have not been made properly. In that
case, tighten the connection or, if necessary,
create a new flange.
Pumping down to vacuum
After completing a successful leak test, the excess
pressure in the refrigerant pipes is removed and a
vacuum pump with an absolute final partial pressure of min. 10 mbar is used to remove all of the
air and empty the pipes. Any moisture present in
the pipes will also be removed.
NOTICE!
A vacuum of at least 10 mbar must be produced!
45
REMKO CMF/CMT
The time required to generate the vacuum is
dependent on the final pressure pipe volume of the
indoor units and the length of the refrigerant pipes.
This always takes at least 60 minutes. Once any
foreign gases and humidity have been completely
extracted from the system, the valves on the pressure gauge station are closed and the valves on
the outdoor component are opened as described in
the "Commissioning" section.
Commissioning
NOTICE!
Commissioning should only be performed and
documented by specially trained personnel.
Observe the operating manual for the indoor
units and outdoor components when commissioning the entire system.
Once all components have been connected and
checked, the system can be commissioned. To
ensure the proper functioning of the units, a functional check must be performed prior to handover
to the operator in order to detect any operational
irregularities. This check is dependent on the
installed indoor units. The processes are specified
in the operating manual for the indoor units being
commissioned.
Functional checks and test run
Check the following points:
n Leak-tightness of the refrigerant pipes.
n Compressor and fan running smoothly.
n Function test of the indoor units and all pro-
gram sequences.
n Check of the surface temperature of the suc-
tion pipe and that the vaporiser is not overheating. To measure the temperature, hold the
thermometer to the suction pipe and subtract
the boiling point temperature reading on the
pressure gauge from the measured temperature.
n Record the measured temperatures in the
commissioning report.
Function test of heating operating mode
1. Remove the protective caps from the valves.
2. Start the commissioning procedure by briefly
opening the shut-off valves on the outdoor
component until the pressure gauge indicates a pressure of approx. 2 bar.
3. Check all connections for leaks with leak
detection spray and suitable leak detectors. If
no leaks are found, fully open the shut-off
valves by turning them anti-clockwise using a
spanner. If leaks are found, draw off the
refrigerant and rework the defective connection. It is imperative that the vacuum creation
and drying steps are repeated!
4. Activate the main circuit breaker or fuse (to
be provided by the customer).
5. Program the heat pump manager.
6. Switching on heating mode
Due to the switch on delay, the compressor will start up a few minutes later.
7. Check the correct function and settings of all
regulation, control and safety devices during
the test run.
8. Measure all cooling data and record the
measured values in the commissioning
report.
9. Remove the pressure gauge.
Final tasks
n Use the heat pump manager to set the target
temperature to the required value.
n Re-install all disassembled parts.
n Instruct the operator on how to use the units.
NOTICE!
Check that the shut-off valves and valve caps
are tight after carrying out any work on the
cooling cycle. Use appropriate sealant products as necessary.
46
Adding refrigerant
DANGER!
The connection of refrigerant pipes and the
handling of refrigerant may be only be carried
out by qualified personnel (competence category I).
DANGER!
Only refrigerant in a liquid state may be used to
fill the cooling cycle!
CAUTION!
Danger of injury from refrigerant!
Refrigerant degreases the skin on contact and
may cause cold burns.
Therefore:
- Wear chemical-resistant protective gloves
when undertaking any work involving refrigerants.
-Safety glasses must be worn to protect the
eyes.

NOTICE!
Check the overheating to determine the refrigerant fill quantity.
n The outdoor unit is pre-filled with refrigerant
sufficient for a length of ordinary pipe up to 30
metres.
n If the length of any of the pipelines exceeds 30
metres, then an additional filling of 600g for
each 10 metres of pipe length (basic length) is
required.

8.1 General notes
n It is necessary to lay a power-supply cable
both to the outdoor unit and, separately, to the
indoor unit.
n Power to the indoor unit may not be discon-
nected by the power company (Frost protection).
n All indoor- and outdoor modules series CMF/
CMT 120 require a single-phase power supply
at 230 V / 50 Hz.
The outdoor modules series CMF/CMT 160
require a three-phase power supply at 400 V /
50 Hz.
n The electrical connection between outdoor-
and indoor units is made using four-wire control cable.
n Where applicable, a separate power supply
shall be provided to the indoor unit for electric
booster heating.
n The heat pump manager needs to know
whether a power-company release- or offperiod is in effect. An electrically-isolated
switch must be installed for this purpose. (An
open switch signifies power available, an open
switch, off-time.)
n In the chapter "Connection diagram, terminal
configuration" in this manual can be found a
connection schematic along with corresponding circuit diagrams.
n Special rates for heat pumps may be offered
by the power company (PSC).
n Ask your local power company about the
details of any rates that might be available.
WARNING!
Always note the currently applicable VDE
guidelines and the notes in TAB 2007. The size
and type of the fuse are to be taken from the
technical data.
WARNING!
All cable sizes are to be selected according to
VDE 0100. Special attention should be given to
cable lengths, cable type and the kind of installation. The information in the connection diagram and in the system overview are to be
seen as an acceptable installation possibility
only in a standard case!
NOTICE!
Make sure to connect the outdoor unit neutral
connector properly, otherwise the varistors on
the line-filter circuit board will be destroyed.

Temperature sensors
n The number of sensors required can vary with
the type of system.
n In the indoor module (F11), the collector
sensor, the return sensor (F17) and the sensor
for the liquid line (TH2-Refrigeration circuit) are
already installed and connected.
n Observe the pertinent notes for the sensor
position found in the hydraulic schematic.
n The standard model includes an external
sensor (F9), a submersible sensor (intended
for use as a custom hot-water sensor - F6), as
well as a sensor for a. total supply (T-CollectorF8).
n When connecting solar panels, the PT-1000
sensor must be used to measuring the collector temperature! (F14) All other sensors
must be NTC-sensors with a reference resistance of 5 kilo Ohms by 25 °C.
n All sensors are to be connected to the indoor-
module switching-cabinet according to the terminal-assignment diagram.
If the sensor cables are too short, they can be
extended up to a maximum of 100m with wire
having a cross-section of 1.5 mm².
External sensor
The connection of an outdoor sensor is always
required for the heat pump manager.
n Mount the outdoor sensor pointing skyward, in
a north-easterly direction, about 2.5 metres
above the ground. It may not be subjected to
direct sunlight and is to be protected against
excessive wind. Installation above windows or
air ducts is to be avoided.
n In order to carry out the installation, remove the
cover and secure the sensor with the screws
provided.
n A cable with wire cross-sections of 0.5 mm² is
recommended for connecting the sensor.
Contact sensor
Contact sensors can be mounted on the pipes, to
measure the heating-circuit temperatures, for
example.
n The contact sensor is fastened to a pipe with
the trapezoidal brackets and retaining strap
provided.
n Clean the mounting point on the pipe. Subse-
quently a thermal compound (A) is applied and
the sensor is fixed in position.

NOTICE!
The commissioning and programming of the
heat-pump manager may be carried out only
by an installer authorized by REMKO.
Please review the heat-pump manager manual
for important details about successful commissioning.
During commissioning, only a typical heatmanager pre-set is made. Individual settings
must be optimized for construction materials
and the practices of various users. Especially
during the first heating period. A review of
energy consumption and efficiency of the heat
pump is recommended at regular intervals.

11 Care and maintenance
Regular care and maintenance serves to ensure
trouble-free operation and long service-life of the
heat pump system.
Care
n The indoor and outdoor units must be kept free
of soiling, vegetation and other deposits.
n The device is to be cleaned with a damp cloth.
In doing so, it is to be ensured that no caustic,
abrasive or solvent-based cleaning products
are used. Use of powerful water jets is to be
avoided.
n The fins on the outdoor unit are to be cleaned
at least once a year.
Maintenance
n To perform the possibly statutory seal test, it is
necessary to arrange an annual maintenance
contract with an appropriate specialist firm.
12 Temporary shut-down
The system may not be switched off at the mains
power supply even if the heating system is not
used for heating purposes over an extended period
(e.g. holidays)!
n The system is to be switched to "Stand-by"
mode during temporary shut-down periods.
n Heating phases can be programmed for the
duration of the period of absence.
n The previous operating mode has to be
switched back on when the shut-down phase
is over.
n Instructions for changing the mode appear in
the corresponding chapter of the heat-pump
manager's manual.
NOTICE!
In "Standby" , the heat pump is in standby
mode. Of the entire system, only the frost-protection function s activated.
NOTICE!
As the refrigerant capacity exceeds 3 kg, an
annual seal inspection must be made of the
refrigerant circuit by a firm specializing in this
field. A heating system should always be serviced annually. Therefore, we recommend
arranging for a service contract that includes
the seal inspection.

15 General terms
Annual power input factor
The annual power input factor indicates the power
input (e.g. electrical energy) required in order to
achieve a certain benefit (e.g. heating energy). The
annual power input factor includes the energy
required for auxiliary drives.
Bivalent mode
The heat pump provides the entire heating energy
down to a predetermined outdoor temperature
(e.g. -3°C). If the temperature drops below this
value, the heat pump switches off and the secondary heating appliance takes over the heating, e.g.
a heating boiler.
Coefficient of performance
The current ratio of thermal output produced by the
heat pump to the consumed electrical power is
referred to as the coefficient of performance, as
measured under standardised boundary conditions
according to EN 255 / EN 14511. A coefficient of
performance of 4 means that a usable thermal
output amounting to 4-times the electrical power
consumption is available.
Energy supply company switching
Certain energy supply companies offer special tariffs for the operation of heat pumps.
When switching off the power supply companies only on the barrier is in contact only
requirement of a heat source (heat pump) is
blocked. Be switched off at monoenergetic
operation, the power supply of the electric
heating element with.
Evaporator
Heat exchanger on a refrigerant plant which uses
the evaporation of a working medium in order to
extract heat from its environment at low temperatures (e.g. the outdoor air).
Expansion valve
Heat pump component for lowering the condensing
pressure on the vapour tension. In addition, the
expansion valve regulates the quantity of injected
refrigerant in relation to the evaporator load.
Compressor (condenser)
Unit designed for the mechanical conveyance and
compression of gasses. Compression serves to
significantly increase the pressure and temperature of the medium.
Condenser
Heat exchanger on a refrigerant plant which liquefies a working medium in order to transmit heat to
its environment (e.g. the heating system).
Defrost
At outdoor temperatures below 5°C it is possible
that ice may form on the evaporators of air/water
heat pumps. The removal of this ice is referred to
as defrosting and is undertaken by supplying heat,
either regularly or as requirements dictate. Air/
water heat pumps with circuit reversal are distinguished by their requirements-based, quick and
energy-efficient defrosting system.
Heat carrier
Liquid or gas medium (e.g. water, brine or air), in
which heat is transported.
Heat pump system
A heat pump system consists of a heat pump and
a heat source system. For brine and water/water
heat pumps, the heat source system must be
made available separately.
Heat source
Medium from which the heat pump derives heat, in
other words, soil, air and water.
Heating output
Flow of heat emitted from the liquefier to the environment. The heating output is the sum of the electrical power consumed by the condenser and the
heat flux obtained from the environment.
Inverter
Power regulator which serves to match the speed
of the compressor motor and the speed of the
evaporator fans to the heating requirement.
84
Limit temperature / bivalence point
Outdoor temperature where the secondary heating
appliance cuts in under bivalent operation.
Monovalent mode
In this mode, the heat pump is the sole heating
appliance in the building all year round. Monovalent mode is primarily used in combination with
brine/water and water/water heat pumps.
Noise
Noise is transmitted in media such as air or water.
Essentially there are two types of noise, airborne
sound and solid-borne sound. Airborne sound is
transmitted entirely via the air. Solid-borne sound
is transmitted in solid materials or liquids and is
only partially radiated as airborne sound. The
audible range of sound lies between 20 and
20,000 Hz.
Refrigerant
The working medium used in a refrigerant plant,
e.g. heat pump, is referred to as the refrigerant.
The refrigerant is a liquid which is used for thermal
transfer in a refrigeration plant and which is able to
absorb heat by changing its state at low temperatures and low pressures. A further change of state
at higher temperatures and higher pressure serves
to dissipate this heat.
Refrigerating capacity
Seasonal performance factor
The seasonal performance factor relates to the
ratio of heat content delivered by the heat pump
system to the supplied electrical energy in one
year. It may not be compared to the performance
number. The seasonal performance factor
expresses the reciprocal of the annual power input
factor.
Single energy-source mode
The heat pump covers a large proportion of the
required thermal output. On a few days per year an
electrical heating coil supplements the heat pump
under extremely low outdoor temperatures. Dimensioning of the heat pump for air/water heat pumps
is generally based on a limit temperature (also
known as balance point) of approx. -5 °C.
Sound pressure level
The sound pressure level is a comparable characteristic quantity for the radiated acoustic output of a
machine, for example, a heat pump. The noise
emission level at certain distances and acoustic
environments can be measured. The standard is
based on a sound pressure level given as a nominal noise level.
Split AC unit
Design where one part of the device is positioned
outdoors and the other inside the building. Both
units are connected to each other by a refrigerant
pipe.
Heat flux extracted from the environment by the
evaporator (air, water or soil).
Regulations and guidelines
The erection, installation and commissioning of
heat pumps has to be undertaken by qualified specialist engineers. In doing so, various standards
and directives are to be observed.
Seal inspection
System operators are obliged to ensure the prevention of refrigerant leakage in accordance with
the directive on substances that deplete the ozone
layer (EC 2037/2000) and the Regulation on Certain Fluorinated Greenhouse Gases (EC
842/2006). In addition, a minimum of one annual
service and inspection must be carried out, as well
as a sealing test for refrigerating plants with a
refrigerant filling weight over 3 kg.
Storage tank
The installation of a hot-water storage tank is generally recommended in order to extend the running
time of the heat pump under low heat requirements. A storage tank is required for air/water heat
pumps in order to bridge off-periods.
