Pre the or key to cycle through the HC-CP-LA-PU-CA parameters. To enter a code, pre the S key, pre the or key to change the desired value and pre SET to save and exit. . Control temperature setting: Short pre S key (not more than 2 seconds) to display the factory default control temperature. Pre or key to change the value well to save automatically. (Pre and hold the or key for 2 seconds to quickly adjust the value.) Heating control: When the temperature control method (code HC) is set to H, for example, the set control temperature value is 28 C, and the temperature difference is 2 C. When the ambient temperature value the set temperature value (28 C), the relay opens and closes the output load; when the ambient temperature value the set temperature value (28 C) - the return temperature (2 C) and the "delay" is set After the start time, the relay pulls up to start the output load; (if the delay function is not needed, the delay start (code PU) can be set to 0). Cooling mode: When the temperature control method (code HC) is set to C, for example, the set control temperature value is 28 C, and the temperature difference is 2 C. When the ambient temperature value set temperature value (28 C), the relay opens and closes the output load; when the ambient temperature value set temperature value (28 C) + hysteresis temperature (2 C) and the "delay start" is set After the time, the relay is sucked and the output load is started: (It is recommended that the delay start time is the default time to protect the compreor. If no delay is required, the code (PU) is set to 0) Menu Code Table: Product schematic Product size chart Package includes: 1 x Temperature controller 1 x Temperature sensor 1 x Instruction manual
