takes heat from bedrock, ground or watercourses, and
delivers it to the house’s existing heating circuit.
The CTC EcoPart i600M has a built-in, energy-ecient (A
rated) circulation pump for connection to the ground/
bedrock circuit, i.e. the cold side. This can be connected to
either the left, right or back of the heat pump, whichever
suits you best.
The CTC EcoPart i600M has a control system that:
• monitors all heat pump functions.
• allows for individual settings.
• Displays desired values, such as temperatures,
operation times, energy consumption and fault
signals
• facilitates the setting of values and
troubleshooting in a simple and well-structured
way.
Easily accessible electrical components and cooling
modules, along with effective troubleshooting functions
in the control program, make the CTC EcoPart i600M easy
to service.
To make installation easier, especially when replacing an
existing heat pump, the product is equipped with a 3-way
valve and double primary ow pipes for heating and hot
water respectively.

3. Your home's heating installation
The House Heating Curve
The heating curve is the central part of the product’s
control system. It is the heating curve which determines
the compensated ow temperature requirements for your
property dependent upon the outdoor temperatures. It
is important that the heating curve is correctly adjusted,
so that you achieve the best operation and economy
possible.
One property requires a radiator temperature of 30 °C
when the outdoor temperature is 0 °C, whilst a different
property requires 40 °C. The difference between different
properties is determined by the radiator surface area, the
number of radiators and how well insulated the house is.
Part of the ”Installer/Settings/Heating Circuit/Heating Circuit 1” menu.
iFor more information on how to set the
heating curve, see section ”Heating curve”
in chapter ” Settings / Heating circuit”.
Menu: ”Installer / Settings / Heating Circuit / Heating Circuit 1/Heating
curve/Fine adjustment".
Menu: ”Installer / Settings / Heating Circuit / Heating Circuit 1/Heating
curve". Active curve: #1.
Adjusting the heating curve
In the ”Heating curve” menu under ”Settings/Heating
circuit”, you can ne adjust the values of the heating
curve for the primary ow temperature in relation to
the outdoor temperature in the graph, as well as set the
values for curve inclination and curve adjustment for the
heating circuit.
See section ”Heating curve” in chapter ”Settings/
Heating circuit” for detailed information.
Ask your installer to help you set these values.
It is extremely important to set the heating curve and, in
some cases, unfortunately, this process may take several
weeks. The best way of doing this, upon the initial start-
up, is to select operation without any room sensor. The
system then operates using the outdoor temperature
reading and the property’s heating curve only.
During the adjustment period it is important
that:
• the night reduction function is not selected.
• all thermostat valves on the radiators be fully
opened. (This is to nd the lowest curve for the
most economical use of the heat pump).
• the outdoor temperature is not higher than
+5 °C.
• the radiator system is operational and correctly
adjusted between different circuits.

8
Adjusting the heating curve
The method described below can be used to adjust the
heating curve correctly.
Adjustment if it is too cold indoors:
• If the outdoor temperature is lower than 0 degrees:
Increase the Inclination value by a couple of degrees.
Wait 24 hours to see if any further adjustment is
required.
• If the outdoor temperature is higher than 0 degrees:
Increase the Adjustment value by a couple of
degrees. Wait 24 hours to see if any further
adjustment is required.
Adjustment if it is too warm indoors:
• If the outdoor temperature is lower than 0 degrees:
Decrease the Inclination value by a couple of
degrees.
Wait 24 hours to see if any further adjustment is
required.
• If the outdoor temperature is higher than 0 degrees:
Decrease the Adjustment value by a couple of
degrees.
Wait 24 hours to see if any further adjustment is
required.
iThe set heating curve always takes priority. The room sensor can only increase or decrease the heat
beyond the set heating curve to a certain extent. Where operating without a room sensor, the selected
heating curve determines the ow temperature supplied to the radiators.
Appropriate Default Values
During installation you can seldom achieve a precise
setting for the heating curve instantly. In this case, the
values given below may provide a good starting point.
Radiators with small heat-emission surfaces require a
higher primary ow temperature. You can adjust the
gradient (heating curve gradient) for your heating system
under the "Installer / Settings / Radiator system" menu.
Recommended values are:
Floor heating only: Inclination 35
Low temperature system: Inclination 40
(well insulated houses)
Normal temperature system: Inclination 50
(factory setting)
High temperature system: Inclination 60
(older houses, small radiators, poorly insulated)

9
Examples of Heating Curves
You can see in the diagram below how the heating curve
changes with different Inclination settings. The gradient
of the curve shows the temperatures that the radiators
require at different outdoor temperatures.

Adjustment
The curve can be parallel displaced (adjusted) by the
desired number of degrees to adapt to different systems/
houses.
An example
Inclination 60 °C
Adjustment 0 °C
In this example, the maximum outgoing primary ow
temperature is set at 55 °C.
The minimum permitted primary ow temperature is
27 °C (e.g. summer-time basement heating or the oor
circuits in a bathroom).

iIf the values set are too low, this may mean that the desired room temperature is not being reached.
You then need to adjust the heating curve, as necessary, following the method shown above.

Curve Inclination
The inclination value which is set is the primary ow
temperature when the outside temperature is –15 °C.

ºC
ºC
Summer season
All properties have internal heat gains (lamps, oven,
body heat, etc.), which means that the heating can be
switched off when the outdoor temperature is lower than
the desired room temperature. The better insulated the
house is, the earlier the heating from the heat pump can
be switched off.
The example shows the product set at the default value of
18°C. This value, "Heating off, outside", can be changed
in the "Installer / Settings / Heat circuit" menu.
In systems with a radiator pump, the radiator pump
stops when the heat is switched off. The heating starts up
automatically when it is required again.
See chapter ”Settings/Heating circuit” for information on
setting the heating mode.

7. Pipe installation
The installation must be carried out in accordance with the applicable
standards. The product must be connected to an expansion vessel in
an open or closed system. Do not forget to ush the heating circuit
clean before connecting. Apply all the installation settings based on the
description in the section entitled "First start".
7.1 Detaching the front
In order to adjust the pressure in the expansion vessel and check the pipe
ttings before the rst start, the front needs to be dismantled.
1. Remove magnetic strip.
2. Loosen the two screws securing the front to the top cover.
3., 4. Fold out and lift off the front. Set it to one side.
NOTE! Bear in mind that the cable to the display on the front is sensitive
to damage.
7.2 Pipe connections, heating medium side
Route the pipes so that no other highest point is present where air can
collect and obstruct circulation. If this cannot be done, however, provide
this highest point with an automatic bleeder.
7.2.1 Filling valve, heating circuit
Fit a lling valve between the cold water connection and the heating
circuit’s return ow.
7.2.2 Non return valve
Fit the non-return valve to the incoming cold water connection.
7.2.3 Shut-o valves
It is important to t a shut-off valve to the primary ow.
7.2.4 Safety valve
The heat pump’s safety valve (2.5 bar) for the heating circuit must be tted
in accordance with applicable regulations. Connect the waste pipe to the
waste system directly to the oor drain or, if the distance is more than two
metres, to a funnel. The waste pipe must slope towards the waste system,
be installed frost-free and left open to the atmosphere/without pressure.
7.2.5 Manometer – system pressure
Fit a manometer to the expansion vessel or the heating circuit’s return
line.
1. Magnetic strip
2. Screws x 2
3. Fold out front
4. Lift front up
and out
!NB: The waste pipe must
be tted to the waste
system.
!NB: It is important to t
shut-o valves to both
the primary and return
ows.

7.2.6 Connection of expansion vessel (accessory)
The heat pump is designed to be tted to an 18 l closed expansion vessel.
Install the expansion vessel
1. Attach the supplied bracket to the rear panel on the inner stand. Push
the bracket down so that it attaches to the stand.
2. Insert the expansion vessel into the bracket so that the vessel’s
connection is free to connect to the expansion hose. To connect the
expansion hose to the product, the plug cone must be removed from
the T-connection on the return line.
3. Place the mounting pad between the expansion vessel and the
junction box.
If you are using an open system, the distance between the expansion vessel
and the highest placed radiator must not be below 2.5 m in order to avoid
introducing oxygen into the system.
If the heat pump is connected together with another heat source, e.g. an
existing boiler, the installations must have separate expansion vessels.
7.2.7 Expansion vessel pre-pressure
The pre-pressure in the expansion tank is calculated according to the
height (H) between the highest-positioned radiator and the expansion
tank. The pre-pressure must be checked/set before the system is lled
with water. The system pressure must be set 0.3 bar higher than the pre-
pressure in the expansion vessel. For example, a pre-pressure of 1.0 bar
(10 mvp) means a maximum permitted height difference of 10 m.
The table assumes the installation of the expansion vessel that is
included in the accessory kit for the heat pump.
