12.1.62 RTC — Setpoint error
Name
Object function
Data type
RTC: Setpoint error
Output
1.001 Switching
The RTC sends value 1 via the communication object when a setpoint telegram has been
received, the value of which is invalid. If a telegram with a valid value is received, it takes on
value 0. The telegram is sent when its value changes.
Invalid temperature values are those that require a higher energy level than comfort mode or in
validate the temperature range for heating and cooling. Example: For a temperature value of
21°C for heating comfort, values for heating standby higher than 21°C are not permitted. Or. For
a temperature value of 21°C for heating comfort, values for cooling comfort smaller than 22°C
(21°C + 1 K safety distance between heating and cooling) are not permitted.
12.1.63 RTC: Limit temperature basic heating stage
Name
Object function
Data type
RTC: Limit temperature basic heating stage
Input
9.001 Temperature value
The communication object receives the measured temperature value for the limit temperature of
the basic heating stage. If, for example, the basic heating stage controls the floor heating, then
the floor temperature is received via this communication object. If the temperature received
exceeds the limit value, the control value is set on zero.
12.1.64 RTC - Limit temperature additional heating stage
Name
Object function
Data type
RTC: Limit temperature additional heating
stage
Input
9.001 Temperature value
The communication object receives the measured temperature value for the limit temperature of
the additional heating stage. If, for example, the basic heating stage controls the floor heating,
then the floor temperature is received via this communication object. If the temperature received
exceeds the limit value, the control value is set on zero.
12.1.65 RTC - Limit temperature basic cooling stage
Name
Object function
Data type
RTC: Limit temperature basic cooling stage
Input
9.001 Temperature value
The communication object receives the measured temperature value for the limit temperature of
the basic cooling stage. The function is analogue to the heating limit temperature.
