General Information
You have just bought a CTC EcoLogic, which we hope
you will be very pleased with. The following pages
provide information on how to operate your CTC
EcoLogic. One part contains general information for
the property owner etc. and one part has been written
for the installer. Keep this handbook containing the
installation and maintenance instructions. You will be
able to enjoy the benefits of your CTC EcoLogic for
many years, and this manual provides all the information
you will need.
The CTC EcoLogic is available in two different models:
the EcoLogic PRO and the EcoLogic Family. The
EcoLogic PRO has more functions than the EcoLogic
Family. These are marked * in the manual. The EcoLogic
Family can easily be upgraded to the EcoLogic PRO by
installing an expansion card.
The Complete System
CTC EcoHeat 300 is a complete heat pump which
meets your home’s heating and hot water requirements.
It is equipped with a unique control system that
monitors and controls your entire heating system
regardless of how you choose to tailor it.
Congratulations on buying your new product
The CTC EcoLogic’s control system :
• monitors all hot water and heating system
functions;
• monitors and controls your heat pump, solar
panels
* , additional heat, buffer tank, pool *, etc.;
• allows for individual settings;
• indicates desired values, for instance,
temperatures and energy consumption;
• facilitates settings in a simple and structured
manner.
Service-friendly, second to none
Easily accessible electrical components, along with
effective troubleshooting functions in the control
program, make the CTC EcoLogic easy to service.
It is supplied with a room sensor as standard, which
is equipped with LED lights that flash in the event of
a fault. The CTC EcoLogic is fully designed to work
with the CTC EcoAir outdoor air heat pump, the
CTCEcoPart bedrock/ground source heat pump, solar
panels and an additional boiler where present. The
CTCEcoLogic can control a number of combinations
and provide you with an extremely flexible, eco-friendly
and energy-saving heating system.

General Information
Important to remember!
Check the following points in particular at the time of delivery and installation:
• Remove the packaging and check that the product (electrical
connection box and display) has not been damaged in transit. Report
any transport damage directly to the carrier.
• Check for missing parts.
• The product must not be installed where the ambient temperature is
higher than 60°C.
Safety Instructions
The following safety instructions must be observed when handling, installing
and using the heat pump:
• Do not soak the product with water or any other liquid.
• All installation must be carried out by a qualified person in accordance
with applicable regulations.
• Make sure that the electrical connection box is not left with the cover
open after the installation – bear in mind the risk of electrical hazards to
your safety and the safety of those around you.

General Information
1.2 Heating System
The CTC EcoLogic can control up to four heating systems* using room sensors
– for example, two radiator circuits and two floor heating circuits.
The required curve inclination and adjustment is set when operating outdoor
sensors only. This value is different from home to home and should be adjusted
to suit your needs.

Heating system 1
Heating system 2
Heating system 3
A room sensor that is correctly positioned provides more comfort and
more heating system savings. The room sensor picks up the current indoor
temperature and adjusts the heat, for example when it is windy outside and
the house is losing heat, which the outdoor sensor is unable to register. During
solar insolation, or other instances when heat builds inside the house, the room
sensor can also reduce the heat supplied, thus saving energy. Another way to
save energy is to use the night reduction function, which reduces the indoor
house temperature at certain times or periods, for example during the night or
when you are away on holiday.
Degree minutes, EcoLogic systems 1 to 3
EcoLogic systems 1, 2 and 3 (see the schematic diagrams for EcoLogic
systems 1 to 6 in the “Pipe installation” chapter) measure the control system
temperature in the heating system each minute. Once a certain cumulative heat
loss (measured in degree minutes) is measured, the heat pump is started up to
compensate for the loss.
“Degree minutes” refers to the product of the cumulative heat loss in degrees
(°C) and the time measured for this in minutes. For example, 60 degree minutes
may arise if a total of one degree of heat loss accumulates for one hour, or three
degrees of cumulative heat loss is measured after 20 minutes.
The first heat pump starts when heat loss reaches 60 degree minutes (factory
setting) and stops when the system has recovered the loss (at 0 degree
minutes). If several heat pumps are connected at the same time as the heat loss
increases, the A2 heat pump starts when there is a loss of 90 degree minutes
(the factory-set difference between the heat pumps is 30 degree minutes). If
additional heat is needed, this is added when there is a heat loss of 500 degree
minutes and stops at 400 degree minutes (both values are factory set).
*Applies to the CTC EcoLogic PRO
only. The CTC EcoLogic Family
controls up to two heating systems.

General Information
Buffer tank
HP A1
1.2.1 Heat pump
The CTC EcoLogic can control up to ten heat pumps*, two of which can be
connected via diverting valves to deliver heat to either the heating system or
the hot water system.
The heat pump works in different ways depending on whether it is the hot
water or heating system that is being charged.
Heat pump operation is a so-called floating condensation, where the
heat pump heats to the temperature required by the heating system. This
temperature varies depending on the outdoor temperature and which set
inclination and adjustment of the heat curve has been chosen. Installed room
sensors affect the temperature required in the heating system.
Savings from a heat pump are directly linked to the COP value. COP means
the output in proportion to the supplied power. Thus, COP = 3 means that
for 1 kW of supplied power from the compressor, 3kW of heat output is
produced.
The lower the temperature the heat pump needs to produce, the higher the
COP value obtained from the heat pump, as this is a more advantageous
operation for the compressor. The heat pump therefore only heats to the
temperature required by the heating system. This is economical both in
terms of the service life of the compressor and in maximising operating
economy.
Buffer tank, EcoLogic systems 4 to 6
If a buffer tank is connected (see the schematic diagrams for EcoLogic
systems 4 to 6 in the “Pipe installation” chapter), the heating system can be
kept at a constant temperature.
The heat pump is controlled based on the temperature in the buffer tank.
The compressor starts at a certain predefined time after the sensor in the
tank measures a temperature that is lower than the setpoint for the tank and
stops when the tank measures a temperature difference that is set higher
than the setpoint for the tank. The indoor temperature in conjunction with the
outdoor temperature and chosen heat curve determine at which temperature
the primary flow temperature will be aimed.
*Applies to the CTC EcoLogic PRO
only. The CTC EcoLogic Family can
control up to two heat pumps.
