Heat request is started when the flow temperature is continuously below reference temperature for 1 minute.
Reference/
This value determines the acceptable underflow of the heating circuit temperature beyond the calculated reference flow tem-
perature at the buffer sensor or flow sensor. If the temperature at the buffer sensor exceeds the reference flow temperature by the
value set here, the heating request is deactivated.
The setting value reference/ appears only in the menu if a sensor has been set under buffer sensor.
Heat request is started when the flow temperature is continuously below reference temperature for 1 minute.
Turn off HC
Summer:
HC turns off when the summer/winter changeover (outside temperature) is exceeded.
Room:
HC is turned off when the summer/winter changeover (outside temperature) or the room setpoint temperatures
are exceeded.
Buffer sensor
Input of heating circuit buffer sensor
In this menu, the sensor is set, which is used as a reference sensor for the heating circuit request.
The request only works if an energy source (burner, compressor, solid chamber) is activated as an additional function
and if this source is set for the heating circuit request
(see also burner: see " Heating Circuit request " on page 18
Room Controller
This value is used to appoint the amount of influence the room temperature has on the reference flow temperature, as a per-
centage. For each degree deviation between room temperature and set point temperature, the percentage set here is added
from the calculated set flow temperature to the set flow temperature or subtracted from it until the min. or max flow values.
Example: Reference room temp.: e.g. 25 °C; room temp.: e.g. 20 °C ±5 °C. Calculated reference temp.: e.g. 40 °C: room con-
troller: 10 %= 4 °C 5 X 4 °C= 20 °C. Accordingly, 20 °C are added to the reference flow temperature, giving 60 °C. If the value is
higher than the one set in max. flow temp, the resulting temperature is the one set in max. flow temp.
Room Reference (Day)
The desired room temperature for day mode. As long as this temperature is not reached, the reference flow temperature is
raised and/or lowered according to the percent setting in ‚room controller‘. If ‚room controller‘ is set to 0 %, this function is deac-
tivated.
Room Reference (Night)
The desired room temperature for night mode. As long as this temperature is not reached, the reference flow temperature is
raised and/or lowered according to the percent setting in ‚room controller‘. If ‚room controller‘ is set to 0 %, this function is deac-
tivated.
In the modes ‚Set point‘ and ‚Set point program, the room controller has no influence.
Thermostat (X)
The room controller is selected here. If no room controller is connected and a room controller is connected via the CAN Bus,
another room controller can be selected here.
The CAN bus ID of controller is shown in Menu 'Special Functions' under 'Network'. In °CALEON see the CAN Bus ID in the
expert menu under Network. Choose the Room Controller with the CAN Bus ID of the corresponding controller.
Sensor Typ
If a sensor input is connected to a room controller, it must be set here whether it is a room temperature sensor (RC20) or a switch-
ing contact.
Mixer
This menu contains all settings relating to the mixer of the heating circuit.
Direction
Direction of the mixing valve can be set here.
Mixer turn time
The mixer is switched on i.e. is opening or closing for the time span set here, then the temperature is measured to control the flow
temperature
