Display of store temperatures
TSTB, etc.
Store temperatures
Display range: -40 … +260 °C
Displays the current store temperature.
• TSTB : Store temperature base
• TSTT : Store temperature top
in 2-store systems (only if available):
• TST2T : Temperature store 2 top
• TST2B : Temperature store 2 base
• TSTTS : Temperature heat exchange source
• TST2S : Temperature heat exchange sink
• TSTSF : Temperature store - solid fuel boiler
Display of temperatures at S3 and S4
S3, S4
Temperature sensors
Display range: -40 … +260 °C
Indicates the current temperature at the corresponding additional sensor
(without control function).
• S3 : Temperature sensor 3
• S4 : Temperature sensor 4
Note
In systems with return preheating, S3 is used as the heat source sen-
sor TSTR.
Display of further temperatures
TSFB, etc.
Further measured temperatures
Indication range: -40 … +260 °C
Indicates the current temperature at the corresponding sensor. The display of
these temperatures depends on the system selected.
• TSFB : Temperature solid fuel boiler
• TRET : Temperature heating return
• TSTR : Temperature store return preheating
• TFHQM : Temperature ow (HQM)
• TRHQM : Temperature return (HQM)
• TAH : Temperature afterheating
Display of ow rate
L/
Flow rate
Indication range: 0 … 9999 l/h
Indicates the currently measured ow rate. This value is used for calculating
the heat quantity supplied (V40).
