Default setting
Fixed-setpoint controller and Controller 1 are set up.
In order to function properly, the controller requires an actual value, a setpoint value, and an
output that influences the actual value (for example, a heat source via a relay as a two-state
controller). Autotuning can only detect new parameters with a closed control loop.
