Unable to change the setpoint on CAL Controller
If you cannot change the temperature setpoint on a CAL 3200, 3300, 9300, 9400 or 9500, check that you do not have the setpoint lock parameter set to ON.
The setpoint lock parameter (SP.LK) is in level 1.
When this parameter is set to OFF (unlocked), you can change the setpoint from the normal operator mode by holding down the STAR (*) key and using the UP or DOWN key to change its value
