SECOND SETPOINT (SP2)

The second setpoint SP2 can be used to trigger an alarm or as a proportional control output.

TO CONFIGURE SP2 AS AN ALARM

Enter program mode.

dV.hi sets off alarm signal when temperature rises above a pre-set temperature above the setpoint.

dV.Lo sets off alarm signal when temperature falls below a pre-set temperature below the setpoint.
