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, fl ow 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 fi ne-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 fl ow, before the existing heating system.
Preferably by interrupting the return fl ow from the heating circuit.
