2. EcoLogicS areas of use
2.1 Heating systems with/without 3-way valve
System description
Thanks to the settings options in EcoLogicS, operation of the heat pump can be adapted to
the existing boiler’s conditions and settings.
The control of the existing heating system manages the distribution of heat and hot water in the
same way as before.
Conditions
The installation must be adapted on a case-by-case basis depending on the conditions of the
existing heating system. It is important that installation is carried out in full accordance with the
respective product’s installation instructions. Refer to the relevant heat pump manual for details
about electrical installation, flow requirements, volume requirements, temperature requirements
and more. In some cases, the existing boiler’s settings may need to be adapted to enable heat
pump installation.
The heat pump’s operating parameters must be adjusted in relation to the existing heating
system setting. The main principle is that EcoLogic S should be the primary heat producer and
receive the start signal before the boiler.
The settings must be adjusted to minimise the need for additional energy. This is done by
setting the heat pump’s heat curve a few degrees higher than the existing boiler’s heat curve.
To optimise the heating circuit, these settings should be subsequently fine-tuned for optimal
functionality under different operating conditions.
Note that EcoLogicS and the heat pump should be considered supplementary to the existing
heating system in terms of safety functions such as additional heat and backup heating
thermostat. These functions will be retained in the existing heating system.
2.1.1 Heat pump for existing heating system (without 3-way
valve)
System description
This type of connection allows a ground source or air/water heat pump to be added to the
existing heating system consisting of, for example, heat pump (exhaust air, ground source),
electric boiler, wood boiler, oil boiler or pellet boiler.
Conditions
The heat pump must be installed, in terms of flow, before the existing heating system.
Preferably by interrupting the return flow from the heating circuit.
Figure: Example of system solution with
heating system without 3-way valve

11CTC EcoLogic S
2.1.2 Heat pump for existing heating system (with 3-way valve
solution)
System description
This type of connection allows a ground source or air/water heat pump to be added to the existing heating
system consisting of, for example, heat pump (exhaust air, ground source), electric boiler, wood boiler, oil
boiler or pellet boiler, with 3-way valve control for DHW production.
Conditions
The heat pump must be installed, in terms of flow, before the existing heating system. Preferably by
interrupting the return flow from the heating circuit. In cases where the 3-way valve is located outside the
heating system, the heat pump must be installed before the 3-way valve.
When the 3-way valve switches to DHW, EcoLogic is signalled to activate a fixed setpoint so that the heat
pump can also be used for hot water production.
2.1.3 Replacing a heat pump connected to CTC EcoEl
System description
For installations where the existing heat pump is connected to the CTC EcoEl V1/V2/V3 electric boiler and
the heat pump needs to be replaced.
Conditions
The existing heat pump will be replaced by the new heat pump. The electric boiler power output is limited
in order to minimise the need for additional energy. To optimise the heating circuit, the heat pump settings
should be subsequently fine-tuned for optimal functionality under different operating conditions.
To disconnect the existing heat pump and convert the electric boiler in order to limit the power output,
refer to Appendix "Types of Operation with CTC EcoEl V2".

2.2 Heat pump for Property Control (BMS)
EcoLogic SCTC Heat Pump
System description
For installations where the heat pump must interact with a property control.
Conditions
EcoLogic S is connected to a local network and control signals to the heat pump are sent
via the BMS interface from the existing property control.
Refer to the "Detailed Menu Descriptions" chapter for information on how to define the
Modbus TCP protocol and the digital BMS input, as well as apply settings for heating and
DHW systems.

3.3 Settings
3.3.1 Settings Heating Circuit
Menu: "Installer / Settings / Heating Circuit" when controlling
outdoor sensor.
Example
Inclination 50 means that the temperature to the
external heating tank will be 50°C when the outdoor
temperature is -15°C if Adjustment is set to 0. If
Adjustment is set to +5°C, the temperature will
be 55°C instead. For all outdoor temperatures the
inclination is increased by 5°C, i.e. inclination is parallel
displaced by 5°C.
Menu: "Installer / Settings /".
3.3.1.1 Control on outdoor sensor/
inclination
EcoLogic S controls the charging of the external heating
tank based on the set heat curve. The inclination of
the heat curve indicates the temperature to which the
external heating tank must charge at different outdoor
temperatures.
The outdoor sensor used depends on the type of heat
pump connected to the system:
• Liquid/water heat pump (CTC EcoPart): -
packaged outdoor sensor must be installed
(refer to the "Electrical installation/Connecting the
control card EcoAir/EcoPart" chapter)
• Air/water heat pump (CTC EcoAir): -the existing
outdoor sensor of the heat pump is used.
Max primary flow °C 55 (30...80)
Maximum temperature (sensor HPout) permitted out to
the external heating tank.
Min primary flow °C 14 (14...65)
Minimum temperature (sensor HPout) permitted out to
the external heating tank.
Start/stop diff °C 5 (1...30)
This menu is used to set the negative hysteresis before
the heat pump starts charging the external heating
tank after the stop temperature (sensor HPout) has been
reached.
Example: If the stop temperature is 55°C and hysteresis
is set to 5°C in this menu, it means the heat pump will
start charging again when the temperature has dropped
to 50°C.
Inclination °C 50 (25...85)
Inclination indicates the temperature the external heating
tank needs at different outdoor temperatures. More
information about this can be found in the "Your home’s
heating settings" chapter.
The value set in this menu is the outgoing flow
temperature to radiators when the outdoor temperature
is -15°C.

3.3.1.2 Remote control
For external control, the Normally Open (NO) or Normally
Closed (NC) mode is determined first for the external
control signal. This is setting is applied in the "Installer /
Define / Remote Control" menu.
Refer to the "Installer / Define / Remote Control" chapter
for more information on how the remote control function
works.
Ext. control temp °C 30 (30...60)
Select the temperature for the external heating tank for
remote control.
This menu bar is displayed if external control is active
(has been defined).
Ext. control temp DHW °C 30 (30...60)
Select the temperature for the external DHW tank for
remote control.
This menu bar is displayed if external control is active
(has been defined).
Other settings in the menu apply when external control
is not active.
Menu: "Installer / Settings / Heating Circuit" for remote control
of external heating or DHW tank.
Menu: "Installer / Settings / Heating Circuit" for remote control
of external DHW tank.
Adjustment °C 0 (-20...20)
Adjustment means that the temperature level can be
raised or lowered at a specific outdoor temperature.
HP max DHW No (No/Yes)
Specify whether the charging temperature should be
raised to 60°C every fourth time the compressor starts.
HP max DHW can only be selected when external
control is not active.
