Changes made for Pathfinder 5226 controllers.

The HPU system that is put on our retrofitted double folders has a temperature feedback sensor to be able to keep track of the temperature and try to keep it at a certain range to keep the oil in a happy place. We already had maximum temperature logic used in junction with the air cooler, but no minimum temperature logic. To take care of this 3 new parameters were added to look at the temperature when it approaches low levels.

Minimum Oil Temperature: Will not let you start the pump if lower than this value. Will Halt and throw error if somehow drops below this value in run.

Minimum Operating Temperature: Will try to turn on a heater if it exists if trying to turn pump on. Will Halt and throw error if it drops below while running.

Minimum Temp to Run Air Cooler: If the air cooler is on it will be turned off under this temperature.
