FUNCTIONAL DESCRIPTION
If the actual value (P01) falls below the setpoint (P10 minus hysteresis P11), relay K1 switches the heating on. The integrated
alarm relay enables error messages via a changeover contact in case of over / under temperature, sensor interruption or sensor
short circuit. In the event of sensor errors, relay K1 switches the heating line off or on, depending on the configuration of the
controller.
