can I change the max temperature control from 175F to 300F?

Asked by: D2018
Thank you for your inquiry. This controller has a pre-programmed maximum setpoint limiter. This can be raised as high as 999°.

How can this be changed to Celsius? All the specifications are given on F and C, so I expected to be able to display C

Asked by: don7893
Hi Don7893, Thank you for the inquiry. Unfortunately this model does not provide for F/C selection in set up parameters. F/C selection is determined by the model# at purchase. Best regards OMEGA

How do you change the setpoint limiter? The little manual says that "Set Point (SP) is the only parameter the user can access without code protection" but I can't find any information on changing the set point limiter. Thanks
