Window function

Option 1 (factory setting):
Set the foot-operated switch function to FS ON.
Limiting the adjustment range to ± 1-99 °C (±1-180 °F) based on a temperature locked using the
„LOCK" function.
The locked temperature therefore represents the middle of the adjustable temperature window.
Option 2:
Set the foot-operated switch function to FS OFF.
Starting from a set, locked temperature, it is possible to set a temperature window of ± 1-99 °C (±1-
180 °F) using the WINDOW function. If the actual temperature is within this window, the potential-free
contact (optocoupler output) becomes conductive.
