1. An automation control unit for heating, ventilating, air-conditioning, and refrigeration systems comprising:
a power connection;
an input to receive an input signal from a controlled heating, ventilating, air-conditioning, and refrigeration device;
a display unit;
a profile input for receiving a digital adjustment profile, wherein the digital adjustment profile comprises a plurality of values, and wherein one of the plurality of values of the digital adjustment profile comprises a value indicative of a number of startup cycles of the controlled heating, ventilating, air-conditioning, and refrigeration device;
a non-volatile memory for storing the digital adjustment profile;
a microcontroller connected to the non-volatile memory, wherein the microcontroller uses the digital adjustment profile and the input signal to determine an analog output signal, and wherein the microcontroller monitors the availability of an automation signal from a building automation system and the number of startup cycles of the controlled heating, ventilating, air-conditioning, and refrigeration device;
a manually operated adjust for adjusting the analog output signal during a manual mode for the automation control unit;
a first signal output for providing the analog output signal to the controlled heating, ventilating, air-conditioning, and refrigeration device;
a second analog output for providing the analog output signal to the building automation system; and
wherein the automation control unit is configured to automatically switch from the manual mode for the automation control unit to an automation mode for the automation control unit when the automation signal is available from the building automation system and the number of startup cycles of the controlled heating, ventilating, air-conditioning, and refrigeration device is exceeded.
