Individual room control
Function description
This function is specially designed for the control of zone valves for heating and/or cooling of
individual rooms. Room temperature thresholds or the operating mode switch on the room sensor
can be utilised to switch between heating and cooling. Shutdown conditions prevent heating or
cooling beyond outside temperature thresholds.
Input variables
Enable
General enabling of the function (digital value ON/OFF)
Enable heating
This enable can be used to block heating mode (digital value,
ON/OFF).
Enable cooling
This enable can be used to block cooling mode (digital value,
ON/OFF).
Room temperature
Analogue input signal for the room temperature
Outside temperature
Optional: Analogue input signal for the outside temperature
Floor temperature
Optional: Analogue input signal for the floor temperature
Time condition status
Digital input signal, ON/OFF (e.g. from the Time switch function)
Set room temperature
Analogue value specifying the set room temperature
Set floor temperature
Analogue value specifying the set floor temperature (only if a floor
temperature sensor is defined)
Offset set room temp
Optional: Analogue value specifying an offset for the set room
temperature
Window contact
Digital input signal, ON/OFF
➢ If the outside temperature sensor is also linked to this function, the heating and/or cooling
mode can be blocked by means of shutdown conditions.
➢ The Time condition status will switch off both heating mode and cooling mode outside
the time window. Therefore if time conditions are not required, the Time condition status
must be changed to User and set to ON.
➢ The frost protection function remains active when Time condition status is OFF.
➢ An OFF signal at the Window contact input variable will switch off heating mode and
cooling mode, or will switch the system to frost protection mode. The system will switch to
frost protection mode if the room temperature is below the T.room frost parameter value.
➢ If a RASPT, RAS-PLUS or RAS-F room sensor is used, the operating mode for the function
can be set using the operating mode switch:
AUTO: The system switches automatically between heating and cooling according to
the settings.
STANDARD: Only heating mode is allowed.
SETBACK: Only cooling mode is allowed (frost protection remains active).
