Automatically switching a controller between snap operation and throttle operation

An apparatus comprising:

• a vessel, a controller coupled to the vessel, and an equipment fluidly coupled to the vessel and electronically coupled to the controller;
• wherein the controller includes a sensor connected to the vessel and a control unit having an electronic circuit board coupled to the sensor, wherein the electronic circuit board is electrically connected to the equipment,
• wherein the electronic circuit board has a processor and memory with instructions stored thereon which cause the processor to control the equipment based on an electrical signal received from the sensor, wherein the instructions further causes the processor of the electronic circuit board of the control unit to:
• operate in a snap operation or a throttle operation for control of the equipment;
• and
• one or both of:
• switch from the snap operation to the throttle operation upon determining a setpoint number of consecutive snap cycles for the equipment each have an actual snap cycle time that is less than a threshold snap cycle time, and
• switch from the throttle operation to the snap operation upon determining an actual controller output signal to the equipment is less than a threshold controller output signal value for a period of time that is equal to or greater than a threshold throttle time.
