This is a picture (example) of Signature’s control panel integrating a “touchscreen” operator interface that interconnects with the furnace’s programmable logic controller. A flat panel color operator interface terminal (touchscreen) provides graphic displays to indicate status of all furnace parameters and alarm conditions.  The panel also provides programming access to all ramp/soak profiles and diagnostic capability to alert the operator to any condition that prevents normal furnace operation.  The interface panel (touchscreen) on the left permits the operator to control all aspects of furnace operation.
