Need operating instructions for Honeywell Model HZ-365C ceramic h

I have a "Sureset" ceramic heater with adjustable thermostat and two heat settings but have misplaced the programming instructions.

I want the heater to come on in my wine cellar if the temperature dips to 55F and shut off once it heats up to 56F. This is how I maintained a constant temperature last winter and it worked well but I can't recall how I programmed it last year.

Thank you
