Operation and function
Display of collector temperatures
COL, COL1, COL2
Collector temperature
Display range: -40 … +260 °C [-40 … +500 °F]
Indicates the collector temperatures.
• COL : Collector temperature (1-collector system)
• COL1 : Collector temperature 1
• COL2 : Collector temperature 2
Display of store temperatures
TST, TSTB, TSTT, TST1, TST2, TDIS
Store temperatures
Display range: -40 … +260 °C [-40 … +500 °F]
Indicates the store temperatures.
• TST : Store temperature (1-store system)
• TSTB : Store temperature base
• TSTT : Store temperature top
• TST1 : Store temperature 1 (2-store system)
• TST2 : Store temperature 2 (2-store system)
• TDIS : Thermal disinfection temperature
(Arr = 3 only; replaces TSTT if, during thermal disinfection, the heating period DDIS
is active)
Display 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.
Display of further temperatures
TFSB, TRET, TFL, TR
Further measured temperatures
Display range: -40 … +260 °C [-40 … +500 °F]
Indicates the current temperature at the corresponding sensor. The display of these
temperatures depends on the system selected.
• TFSB : Temperature solid fuel boiler
• TRET : Temperature heating circuit return preheating
• TFL : Temperature flow
• TR : Temperature return
Note
TFL / TR will be indicated only if the heat quantity measurement option
(OHQM) has been activated.
