Display of collector temperatures
COL
Collector temperature
Display range: -40 … + 260 °C [-40 … + 500 °F]
Indicates the collector temperature.
Display of store temperatures
TST
Store temperature
Display range: -40 … + 260 °C [-40 … + 500 °F]
Indicates the store temperature.
Indication of sensors 3 and 4
S3, S4
Sensor temperatures
Display range: -40 … + 260 °C [-40 … + 500 °F]
Indicates the current temperature at the corresponding additional sensor (without
control function).
• S3: Temperature at sensor 3
• S4: Temperature at sensor 4
Note:
S3 and S4 will only be indicated if the temperature sensors are connected
to the corresponding terminals.
Indication of return temperature
TR
Return temperature
Display range: -40 … + 260 °C [-40 … + 500 °F]
If the heat quantity measurement is activated, the temperature at sensor S4 will be
indicated as TR.
Indication of current pump speed
n %
Current pump speed
Display range: 30 … 100 %
Indicates the current pump speed.
Display of heat quantity
kWh / MWh
Heat quantity in kWh / MWh
Display channel
Indicates the heat quantity produced in the system. For this purpose, the heat quan-
tity measurement option has to be enabled. The flow rate as well as the values of
the reference sensors flow and return are used for calculating the heat quantity
supplied. It is shown in kWh in the kWh channel and in MWh in the MWh channel.
The overall heat quantity results from the sum of both values.
