* If the Controller is equipped with HB/HS alarm detection, the default setting for the Auxiliary Output 1
Assignment is for heater alarms. Therefore, the alarm 1 function is disabled and the Alarm 1 Type is not
displayed. To enable alarm 1, set an output assignment to alarm 1. For details, refer to 4-6-3 Assigned
Output Functions (Assigning Control Outputs Is Not Supported for Position-proportional Models.).
