Re: Best temprature control method for walk in freezer? Thermostat or Pressure switch
I am sure the perfect system control has not been developed yet, despite all the producers claims. There are demand defrost system controllers incorporated with regular cycles . But I still like to have a LP controller/switch to protect the compressor from flood back if some idiot leaves the freezer door open and coil frosts up, which will ignore the stat demand to run, plus have a liquid sv that cycles with compressor.
I am old alright.
