field supplied domestic hot water pump
(On/OFF type). Depending on the
installation and configuration on the user
interface, we distinguish its functionality.

INFORMATION
The tank can be heated via the gas boiler or heat pump.
NOTICE
If a domestic hot water pump for instant hot water is
present in the system ([D‑02]=1), scaling of the boiler heat
exchanger can occur faster due to more frequent domestic
hot water operation.

Savings mode
The user can choose whether switching between operation modes is
either economically or ecologically optimised. Set to Economical,
the system will in all operating conditions select the energy source
(gas or electricity) based on energy prices, resulting in a
minimisation of energy costs. Set to Ecological, the heat source
will be selected based on ecological parameters, resulting in a
minimisation of primary energy consumption.

Primary energy factor
The primary energy factor indicates how many units of primary
energy (natural gas, crude oil, or other fossil fuels, prior to
undergoing any human-made conversions or transformations) are
needed to obtain 1 unit of a certain (secondary) energy source, such
as electricity. The primary energy factor for natural gas is 1.
