Generating the Set Value

One bit switches between the setpoints. In addition to the actual setpoint, there is also a standby setpoint. The standby setpoint can be used to reduce the temperature during operating pauses to a lower value in order to save power. If necessary the steps in the setpoint can be ramped. The parameter set for the setpoints includes a rate of rise and a rate of fall.

The setpoints are restricted to their limits.

In order to permit "heater baking", a soft start can be parameterized. In this case, the temperature is first ramped up from ambient to a low setpoint (fWStartUp). This temperature is then maintained for a period of time (tStartUp), and only after that has elapsed does the ramp up to the actual setpoint begin.
