The following actions occur in response to Outdoor Temperature changes (in the winter months).
1.	When the outdoor temperature falls below a preset value, which is slightly above freezing:
1.		A. The Overhead doors close automatically (as determined by a Temperature Controller which is interfaced to the PLC). B. The furnace is enabled, to warm the building (as determined by the Temperature Controller which is interfaced to the PLC. Else it is disabled, to save energy). C. De-icer solution is dispense on exterior portion of the Conveyor Rail (as determined by the Temperature Controller which is interfaced to the PLC). D. The Seeper Water is automatically turned on, for the coin operated Power-Washer (as determined by its own dedicated Temperature Controller, in the utility room). E. The large (200,000 BTU) Water Heater is enabled, for all water used in the tunnel (as determined by its own dedicated Temperature Controller, in the utility room).
2	When the outdoor temperature rises above a preset value, which is slightly above freezing:
2		A. The Overhead doors open automatically and stay open (as determined by the Temperature Controller which is interfaced to the PLC). B. The furnace is disabled until the outdoor temperature falls below that point where the Overhead Doors are made to close (as in 1-A above). C. The conveyor rail De-icer system is disabled (as determined by the Temperature Controller which is interfaced to the PLC). D. The Seeper Water is automatically turned off, for the coin operated Power-Washer (as determined by its own dedicated Temperature Controller, in the utility room). E. The large (200,000 BTU) Water Heater is disabled, to save energy (as determined by its own dedicated Temperature Controller, in the utility room).
