Efficient temperature setting: less energy, more comfort
Adjusting the heat curve
The two parameters T-slope and T-adjustment are used to
adjust the heat curve:
T-slope:
This parameter is used to change the slope of the graph in a
supply temperature-outdoor temperature diagram. The curves
in the diagram all pass through the point where outdoor and
supply temperatures are both 20°C.
T-adjustment:
The T-adjustment parameter is used to move the curves
vertically (parallel). If the house is not warm enough at
moderate outdoor temperatures, then it is recommended to
increase the T-adjustment setting. A supply information menu
gives useful feedback when adjusting the heat curve.
Economy and comfort modes
The economy mode (ECO) is used to save energy. In heating
mode, the economy mode reduces room temperatures with a
given setback temperature. In cooling mode, the temperature
is increased. Different economy profiles may be applied for the
days of the week. The default setting in the Climate Controller
C-46 is comfort mode (COMF).
Comfort mode
In comfort mode the system keeps a constant temperature in
the room at the setpoint temperature. If an indoor thermostat
is connected to the C-46, the indoor setpoint temperature is
used. In all other cases the supply setpoint temperature is used.
Economy mode
In economy mode the temperature setpoint is automatically
set back for periods of the day when the comfort temperature
is not needed, for example during the night or when no one is
present in the house.

Special knowledge
Heating and cooling mode with season shut-offs
The shut-off functions are there to save electrical energy of the pump. During the P1 periods the pump runs continuously.
In P2 periods it is switched off under certain conditions. Logically this has to be different for heating / cooling through the seasons of the year.
