4.5.4 Boiler - Service
System menu Boiler
Variable mode activated
▪ NO: The boiler temperature is regulated to the boiler
temperature setpoint that is set. When used in
conjunction with a storage tank, this parameter should
be set to “NO”.
▪ YES: The boiler temperature is regulated according to
the calculated flow value for the heating circuit/DHW
tank.
Mixer runtime
Prerequisite: Return temperature control with mixing
valve
Setting the runtime of the mixer used for the return
temperature control.
Recommendation: To reduce vibration of the mixer, do
not set value to less than 150s!
Function of boiler pump collective fault signal
Defines whether and how the input of the boiler pump’s
collective fault message is to be interpreted.
Input for boiler pump collective fault signal
Preferred digital module address of boiler pump collective
fault input
Boiler pump collective fault signal
Current input signal.
Individual evaluation of safety loop available
The safety loop (STB, STB2, water shortage, water
pressure) can be directed to individual inputs, so that
individual fault messages can be output.
4.5.5 Boiler - General settings
System menu Boiler
Modem installed
▪ NO: The boiler does not have a modem for data
transfer installed.
▪ YES: The boiler has a modem for data transfer
installed.
Memory cycle of data logger
If the boiler is equipped with a data logger the most
important boiler data is stored on a SD card. This
parameter specifies at what intervals the recording should
be started.
Output warnings through fault message relays
▪ NO: When there is an “error” or “alarm” the common
fault relay closes.
▪ YES: In addition to an “error” or “alarm”, the common
fault relay closes when a “warning” is present on the
boiler.
Which temperature scale should be used
▪ Celsius (°C): Displayed temperature values and
settings are shown in °C.
▪ Fahrenheit (°F): Displayed temperature values and
settings are shown in °F.
Always log data in °C
▪ YES: In conjunction with a data logger, all temperature
values are saved in °C.
▪ NO: In conjunction with a data logger, all temperature
values are saved in °F.
Send a line break when ASCII data output on
COM2
▪ NO: When a new data set is issued it will be added to
the previous one.
▪ YES: A line break for better visualisation is sent
between the individual data sets.
