4.3.13 Remote Setpoint Fail, rEm.F

If the remote setpoint is enabled (address 276, section 8.7) then the Remote Setpoint parameter ALtSP (address 26, section 8.7) is used as a setpoint provided that a value has been reached within a window of about 5 seconds. If no value is received then the controller falls back to the currently selected setpoint (SP1 or SP2) and an alarm is generated. The alarm consists of the mnemonic rEm.F which is flashed in sequence with other active alarms in the second line of the display. The ALM beacon blinks at the same time.

 

The message disappears when remote setpoint values are sent within the time period.
