THERMOSTAT FUNCTIONS

Timer thermostat
Temperature comparator
Temperature thermostat “Window”
The window function is similar to a thermostat function, but with an additional threshold to start and
stop the output. The “window” is defined by two temperature values (lower and upper limits), each
within a defined range. A fixed hysteresis of ±1K for start and stop is added onto the defined limits.
Only a free (unused) output can be used for the window function.
The relay can also be driven inverted.
Combination of timer and thermostat.
Once at least one of these criteria is met, the
output is activated.
Any temperature difference to a reference sen-
sor will trigger a control signal:
The output is activated once ›dT ON‹ is
reached, and deactivated once ›dT OFF‹ is
reached.
The output is activated, if the temperature is
between upper and lower limits (± hysteresis).
• The output is switched ON when the lower
limit + hysteresis
or
the upper limit - hysteresis
is reached.
• The output is switched OFF when the upper
limit - hysteresis
or
the lower limit + hysteresis
is reached.
