Information level
TRH
backup heater return-line temperature
Sensor input S9 (fixed) is assigned
via parameter
STX (STX set at level
E3 - 1 / 10).
TR
return-line temperature for heat gain
calculation Use parameter
STR t o as-
sign a sensor input. (Level E3 – 4 / 1)
TX
comparison value for heater return-line
temperature when backup heater func-
tion enabled
(e.g., in conjunction with
VISTRON V750LC). Use parameter
STX to assign a sensor input
(parameter 10, E3 – 1 / 10).
TW
heat exchanger or bypass temperature:
A sensor input is automatically assi-
gned when the relevant schematic is
selected (KON, level E 3 -1 / 1).
