HVAC motor control local display and adjustment methods and apparatus for same

A visual local controller for heating, ventilating, air-conditioning, and refrigeration systems comprising:

• a power connection;
• a signal output connected to a controlled heating, ventilating, air-conditioning, and refrigeration device for providing an output signal to the controlled heating, ventilating, air-conditioning, and refrigeration device;
• a display unit to display a display value;
• an input to receive an input signal from the controlled heating, ventilating, air-conditioning, and refrigeration device;
• a run output to turn on the controlled heating, ventilating, air-conditioning, and refrigeration device;
• a signal return path;
• a profile input for receiving a digital adjustment profile, wherein the digital adjustment profile comprises a plurality of values for use in adjusting the output signal for the controlled heating, ventilating, air-conditioning, and refrigeration device;
• the digital adjustment profile comprises:
• a minimum display value of the display of the visual local controller;
• a maximum display value of the display of the visual local controller;
• a minimum output value of the visual local controller;
• and
• a maximum output value of the visual local controller;
• a non-volatile memory for storing the digital adjustment profile;
• a microcontroller connected to the non-volatile memory;
• a manually operated adjust for adjusting the output signal;
• wherein the microcontroller obtains from the digital adjustment profile stored in the non-volatile memory the minimum output value of the visual local controller and the maximum output value of the visual local controller;
• wherein the microcontroller obtains a current output from the manually operated adjust that corresponds to the manually operated adjust;
• wherein the microcontroller obtains from the digital adjustment profile stored in the non-volatile memory the minimum display value of the visual local controller and the maximum display value of the visual local controller;
• wherein the microcontroller uses the minimum output value of the visual local controller, the maximum output value of the visual local controller, and the current output to determine the output signal to supply to the controlled heating, ventilating, air-conditioning, and refrigeration device;
• and
• wherein the microcontroller uses the digital adjustment profile to determine the display value displayed on the display unit between the minimum display value of the visual local controller and the maximum display value of the visual local controller.
