Congratulations on your new product
You have just purchased a CTCEcoHeat400, with
which we hope you will be very pleased. Read about
how you can take care of your heat pump on the
following pages. One chapter is written for the property
owner and one chapter for the installer.
Save this manual containing the installation and
maintenance instructions. If it is looked after
properly, you will be able to enjoy the use of your
CTCEcoHeat400 for many years. This manual will
provide all the information you will need.
The complete heat pump
CTC EcoHeat 400 is a complete heat pump which
meets your home’s heating and DHW requirements. It is
equipped with a motorised mixing valve which ensures
that correct and even temperatures are supplied to
your heating circuit. In addition, CTC EcoHeat 400 has
a built-in circulation pump for connection to ground/
bedrock coils, i.e the ‘cold side’. This can be connected
to either the left, right or back of the heat pump,
whichever suits you best.
CTC EcoHeat 400 has a control system
which:
• 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.
The built-in copper coil provides copious amounts
of DHW. CTC EcoHeat 400 also has a summertime
basement heating function and an underfloor heating
blocking function, which maximises the temperature
supplied to the floor circuits. Using the integrated
night reduction function, you can set and change the
temperature in the house during the day, from one day
to the next.
Easily accessible electrical components, along with
effective troubleshooting functions in the control
program, make the CTC EcoHeat 400 easy to service.
It comes with a room sensor as standard, which is
equipped with an LED that flashes in the event of a fault.
If you want to supplement your CTCEcoHeat400 with
other heating, you can do this easily thanks to two
unique connections. We have decided to call this option
Energyflex. With Energyflex you can, for example:
• Charge your heating circuit with solar energy.
• Allow a water-jacketed stove to contribute heat.
• Connect a pool heat exchanger to heat up a
swimming pool.

CTC EcoHeat 400
Your home's heating installation
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
flow temperature supplied to the radiators.
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 flow 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.
Adjustment of Default Values for the Heating Curve
You define the heating curve yourself for your property by setting two values in
the product control system. This is achieved by selecting the options Inclination or
Adjustment under the "Installer/Settings/Radiator system" menu. 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 find the
lowest curve for the most economical use of the heat pump).
• the outdoor temperature is not higher than +5°C. (If the outdoor temperature
is higher when the system is installed, use the factory set curve until the
outdoor temperature falls to a suitable level).
• the radiator system is operational and correctly adjusted between different
circuits.
1. Your home’s heating settings

10 CTC EcoHeat 400
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.
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.
When the basic values have been set more or less correctly, the curve can
be finely adjusted directly using the Room temp. shown on the home menu
screen.
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 flow 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 (well insulated houses) Inclination 40
Normal temperature system (factory setting) Inclination 50
High temperature system
(older houses, small radiators, poorly insulated) Inclination 60

11
CTC EcoHeat 400
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.
Curve Inclination
The inclination value which is set is the primary flow
temperature when the outside temperature is –15°C.
Primary Flow Temperature
Primary Flow Temperature
Primary Flow Temperature
Outside Temperature
Outside Temperature
Heating off, out
Outside Temperature
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 flow
temperature is set at 55°C.
The minimum permitted primary flow temperature is
27°C (e.g. summer-time basement heating or the floor
circuits in a bathroom).
Inclination 50°C
Adjustment +5°C
Inclination 50°C
Adjustment 0°C

ºC
ºC
Summer-time operation
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 "Advanced/Settings/Heat System"
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.
Automatic or remote-controlled summer period
The factory setting causes "summer" to commence
automatically at 18ºC, as "Heating mode" is set to
"Auto".
Heating,mode Auto (Auto/On/Off)
Auto means automatic.
On means that the heating is on. For systems with
a mixing valve and a radiator pump, the mixing valve
operates to the primary flow setpoint and the radiator
pump is on.
Off means that the heating is switched off. For systems
with a radiator pump, the radiator pump is switched off.
Heating, ext. mode - (- /Auto/On/Off)
Facility for remote control of whether the heating is to be
on or off.
Auto means automatic.
On means that the heating is on. For systems with
a mixing valve and a radiator pump, the mixing valve
operates to the primary flow setpoint and the radiator
pump is on.
Off means that the heating is switched off. For systems
with a radiator pump, the radiator pump is switched off.
- No selection means no function when activated.
