The largest financial savings will be achieved if the
power generated by the fuel cell is consumed on site
alongside the heating energy. To do this, switch on the
energy manager.
The energy manager optimises the start points for the
fuel cell subject to the power consumption and runtime
of the fuel cell. The runtime depends on the heat
demand within the building.
Operating Vitovalor with the energy manager
You can choose between 2 control strategies:
"Ecological":
The optimum start point for the fuel cell module is
calculated using specific emission factors to achieve
the lowest possible CO2 emissions.
"Economical":
The optimal start point for the fuel cell module is
determined by the power supply price, feed-in remu-
neration and gas price.
Your contractor set this price when commissioning
the system. Your contractor can adjust these prices if
required.
Operating Vitovalor without the energy manager
"Energy manager OFF":
If you switch off the energy manager, the fuel cell start
times depend exclusively on the heat demand of the
system.
Information on operation with a power storage sys-
tem:
If the building mains has been disconnected from the
public grid (e.g. power cut), we recommend switching
off the energy manager.
If you want to switch off power generation, select
"Power generation OFF". See chapter "Switching
OFF the system".
Detailed information on the energy manager can be
found in chapter "Terminology" in the Appendix.
