”Temp Deviation” is the value defining the allowed tolerance from the set point. “Temp Time” is the
time for which the temperature may remain outside the allowed tolerance before the controller triggers in

Figure 38. In this example the following settings are displayed (valid only after the system has reached its
stationary state): if Temperature Deviation from set point is 1°C or greater (i.e. if set point temperature is 37°C
and the temperature reaches a value equal or less than 36.0°C or equal or more than 38.0°C) for a period of time
equal or longer than 15 minutes (“Temp time“ set in this example) then the system triggers
