I would not call the instruction manual an instruction manual. The words may be in English but it’s not a language I’ve ever heard before.
First thing I thought I’d try to do is change the display to Fahrenheit. The intrusions only say that you set the value as F. It has zero information on HOW to do that. Nothing on which of the 3 buttons you might push to achieve that. Nothing appears to correlate with CF. Whatever CF means.
Instructions for setting the temperature?
When the temperature is set to the desired temperature it will turn on at that temperature.
Ok but HOW?
Again, which buttons do you push and maybe an example would help. Not sure who wrote the ‘instructions’. But some actual instructions would be helpful. Wow
ACF Greenhouses: Your instructions should be the same as the
SureStat DT10 Thermostat Instruction Manual we list on this page. Page 6 has a pretty detailed description of how to change all settings on the control along with a flow chart to show what each setting does.
1. Hold the SET button until the display flashes.
2. Press UP or DOWN to change setting.
3. Press SET to move to the next setting.
