The controller can be configured for various types of controllers in the factory. Depending on the
type of controller, the outputs may have different functions. The following types of controller are
available from the factory:
• 2-position controller (conventional or PID) with hysteresis (normal case)
• PID-controller with PWM (= Pulse-Width-Modulation) output (quasi-continuous)
• PID-continuous controller
Where there are differences in the outputs, you will find the abbreviations ‘2-position’, ‘PID-PWM’
and ‘PID-cont.’ in Table 1.
