frigorex coca cola chiller

[hts]

I am new to the forum so not sure whether this is in the correct place. We have just purchased a frigorex drinks chiller second hand so unfortunately don't have any instructions. It has an electronic temperature gauge with set, function and up and down buttons. The temperature is too high and I am unable to set it to cooler temp any help would be gratefully appreciated.

is the controller an Eliwell? possibly ID 970 or 971?

Push set, should show set point. Push up or down to desired temp then push set again. That's assuming controller settings not locked.
