DEFROST TIME CLOCK ☃️ have you worked with these, analog or digital? Image below for the Paragon 8145 Defrost Time Clock ⏰ very popular in my field experience in old industrial/commercial refrigeration systems. This is an “analog”/solid state timer used in old/more traditional systems, which do not have a full digital interface. A Defrost Time Clock (like this, within a digital control system) can be used to trigger an electric or refrigerant defrost for evaporator coils which require it. Learning wiring of a solid state control can greatly improve your understanding of a digital operation. Lots of wiring diagrams for Paragon 8145 available via google. One of the more common time clocks 🕰️ 🔥
