Note
The values and adjustment channels shown
depend on the selected system, the func-
tions and options and will only be displayed
in the expert level.
Display of collector temperatures
TCOL(1, 2)
Collector temperature
Display range: -40.0 ... +260.0 °C [-40.0 ... 500.0 °F]
Displays the current collector temperature.
• TCOL : Collector temperature (1-collector
system)
• TCOL1 : Collector temperature 1 (2-collector
system)
• TCOL2 : Collector temperature 2 (2-collector
system)
Display of tank temperatures
TST1 (2, 3)B, TST1 (2)T
Tank temperatures
Display range: -40.0 ... +260.0 °C [-40.0 ... 500.0 °F]
Displays the current tank temperature.
• TST1T : Temperature tank 1 top
• TST1B : Temperature tank 1 bottom
• TST2T : Temperature tank 2 top
• TST2B : Temperature tank 2 bottom
in 3-tank systems only:
• TST3B : Temperature tank 3 bottom
Display of temperatures at S3, S4 and S5
S3, S4, S5
Sensor temperatures
Display range: -40.0 ... +260.0 °C [-40.0 ... 500.0 °F]
Indicates the current temperature at the correspond-
ing additional sensor (without control function).
• S3 : Temperature sensor 3
• S4 : Temperature sensor 4
• S5 : Temperature sensor 5
Display of further temperatures
Note
Only if temperature sensors are connected,
will S3, S4 and S5 be displayed.
Note
For heat exchange etc., S3/S5 are used as
heat source / heat sink sensor respectively.
DTS1, DTS2, SENTH,
TFHQM, TRHQM
Further measured temperatures
Display range: -40.0 ... +260.0 °C [-40.0 ... 500.0 °F]
Indicates the current temperature at the correspond-
ing sensor. The display of these temperatures depends
on the system selected.
: Temperature heat source ∆T function
• DTS1
: Temperature heat sink ∆T function
• DTS2
• SENTH : Temperature thermostat function
• TFHQM : Temperature fl ow (HQM)
• TRHQM :Temperature return (HQM)
Display of fl ow rate
L/h
Flow rate
Display range: 0 ... 9999 l/h
Indicates the fl ow rate in the solar system during en-
ergy metering.
During heat quantity balancing, the fi xed fl ow rate
value adjusted is indicated.
