Glossary of used terms and conceptions
In case of unfamiliar terms in the document you can find the explanation here.
- ALTERNATIVE SOURCE: The heat source is used for systems with solar collectors, masonry
heaters and wood stoves when we either do not have a heat source on hand at any moment or an
automatic switch through the signal from the controller of the device (i.e. in a wood stove) is not
possible.
- AUXILIARY EXTERNAL SOURCE: The heat source found alongside the device (i.e. oil/gas/pellet/
external heater furnace) and can be used either alongside the device alternatively (the either-or sys-
tem) - automatic switch through the signal from the controller of the device. In case of a device mal-
function (in the so-called anti-freeze programme) the alternative source can take over the task of
heating for a short time.
- SPARE SORCE or Backup source: The flow heater which is installed in the device and turns on in
the case of device malfunction (in the so-called antifreeze programme). This ensures temporary
operation for bridging the time until an authorized person from the service company arrives and cor-
rects the error. The spare or additional source can be used as “assistance” to the device under the
so-called bivalent point when the capacity of the device does not cover the losses of the building.
- HEATING WATER: The liquid which flows inside the heating system (pipelines, floor, wall and radia-
tor heating).
- DHW: The water intended for sanitary use (cleaning, showering, washing ...).
- HEAT PUMP (HP): The device which takes energy from the environment and supplied mechanical
work and adds warmth to heating and DHW. In the text below the term ‘device’ will be used for the
heat pump.
- HW: The device takes heat from the earth.
- AW: The device takes heat from the air.
- WW: The device takes heat from groundwater.
- Parameter NORMAL: The desired temperature of heating in the Normal mode of operation.
- Parameter ECO: Lowering the desired temperature in the Eco mode of operation.
- Parameter COMFORT: Raising the desired temperature in the Comfort mode of operation.
