Insulation factor
Depending on the selected factor, the outdoor temperature has an influence on the VL temperature calculation after the set delay.
0= Off, 1= 15 minutes, 2= 60 minutes, 3= 120 minutes, 4= 300 minutes
Better insulated buildings can increase comfort and save energy by increasing the building factor.
Overload protection
If the function is set to "On", it does not matter which state the heating circuit has. If the temperature at the buffer sensor is above Max.
buffer, the heating circuit pump switches on and the setpoint flow rate is fixed to See " Max. Flow " on page 34 -2°C or the adjusted set
point. If the set Max. If the temperature of the buffer falls below 5 Kelvin, the heating circuit switches back to the previous mode.
Min. Flow cooling
Only appears when the operating mode of the heating circuit is set to heating and cooling or cooling.
This value is the upper limit of the reference flow temperature of the cooling.
Max. flow cooling
Only appears when the operating mode of the heating circuit is set to heating and cooling or cooling.
This value is the upper limit of the reference flow temperature of the cooling.
Dew Point protection
Only appears, if the operating mode of the heating circuit is set to heating and cooling or cooling.
Is only active, if humidity is measured (e.g. via a °CALEON Clima room controller). It is calculated from which room temperature there
is unwanted condensation (precipitation) for the currently measured humidity. Dew point monitoring automatically shifts the target sup-
ply temperature in cooling mode to prevent mould formation.
Dew point correction
Only appears, if the operating mode of the heating circuit is set to heating and cooling or cooling. This value moves the internal dew
point characteristic by up to 10 °C in parallel.
Example 1: You determine that there is condensation with the default value, so you increase this correction value.
Example 2: Condensation/precipitation can be ignored, but stronger cooling is required instead. You therefore decrease this cor-
rection value.
In case of reduction of the calculated temperature with the help of dew point correction condensation / perspiration / pre-
cipitation can occur, which, among other things, may cause the formation of mold.
Room Controller Heating Circuit (X)
Here, the settings are made for an optional room controller. The following variants can be used with different functions:
°CALEON Room Controller:
Influence of the room temperature, the room reference temperature as well as of room-specific time programs on the reference flow.
Operating modes of the °CALEON and significance for the HCC:
Off = Heating Circuit Off,
Eco = Reference - Night reduction,
Normal = Reference + daily correction,
Comfort = Reference + daily correction + comfort increase
The selection of an operating mode (Normal, Comfort, Eco or Off) is only valid until a change to another mode is effected
in the time program of the °CALEON.
Example: The operating mode “Off” is activated on the °CALEON. The next change in the time program ends the manually
set operating mode and activates the mode set according to the time program. If a longer shutdown of the heating circuit is
desired, for example, the holiday mode can be used in the °CALEON.
If several °CALEONs are set as room controllers, the operating mode of the HCC is determined by the room with the
greatest energy demand.
