Cooling circuit control
Standard diagram
Function description
Mixer control for a cooling circuit based on specified set temperatures and limit temperatures. The
time condition status can be used to define the permitted cooling times. Shutdown of the cooling
circuit pump is defined by means of parameter settings.
Input variables
Enable
General enabling of the function (digital value ON/OFF)
Enable pump
Enabling of the cooling circuit pump (digital value ON/OFF)
Enable mixer
Enabling the mixer (digital value ON/OFF)
Room temperature
Analogue input signal for the room temperature T.room
Flow temperature
Analogue input signal for the flow temperature T.flow
Outside temperature
Analogue input signal for the outside temperature T.outside
Time condition status
Digital input signal, ON/OFF (e.g. from the Time switch function)
Set room temperature
Analogue value specifying the required set room temperature
Set flow temperature
Analogue value specifying the required set flow temperature
Dew point / flow min.
Analogue value for the dew point temperature
Calendar op. mode
Input signal from the Calendar function for operating mode changeover
(see sub-chapter and Calendar function)
Calendar set room t
Set room temperature when Calendar function is active (see sub-chapter
and Calendar function)
Window contact
Digital input signal, ON/OFF
Offset set room temp
Analogue offset value for the set room temperature
Offset set flow temp.
Analogue offset value which is added to the set flow temperature.
➢ Enable cooling circuit = OFF: The entire cooling circuit is deactivated. The set flow
temperature is set to 200 °C, the effective set room temperature to 50 °C, all the digital
output variables are set to OFF, so the mixer remains unchanged as well.
