  3. Primary Controllers – Americas History Positive • Low-cost • Low-end controller solution • Easy servicing • Long life expectancy RC195 • Negative • No sensor calibration • Requires compressor • No LCD display, stick on setpoint scales • Proportional Control only, no P+I control • Control loop tuning difficult prepared by David H. Jefferson

  4. Primary Controllers – Americas History Positive • Two sensor inputs for setpoint reset • Electronic, not mechanical and requires no maintenance • LCD display • Plug-in terminals RWC Controller • Negative • Heating output is Reverse Acting, cannot change control action. • Temperature controller only. prepared by David H.
