How to set the target temperature?

The aimed temperature range was defined between the “ON TEMP.” and the “OFF TEMP.”

But the F14 determines the working mode, as a refrigeration controller or a heating controller, and the aimed temperature range will be rewritten to default value once you change F14; Therefore It would be best if you confirm the F14 firstly before configuring other parameters.

How to set the temperature for load starts/stops?

  • [On Temp] Key: touch this to check/edit the existing [Temperature value to Turn-on the Load], the character “On Temp” lighting;
  • [Off Temp] Key: touch this to check/edit the existing [Temperature value to Turn-off the Load], the character “Off Temp” lighting.
