1 s Siemens Building Technologies HVAC ProductsField Devices prepared by David H. Jefferson HVAC Products PRIMARY CONTROLLERS AMERICAS REGION

2 s Siemens Building Technologies HVAC ProductsField Devices prepared by David H. Jefferson Primary Controllers Evolution Electronic Time Line RC195 Pneumatic Pneumatic RWC electronic RWD electronic

3 s Siemens Building Technologies HVAC ProductsField Devices prepared by David H. Jefferson Positive Low-cost Low-end controller solution Easy servicing Long life expectancy Primary Controllers – Americas History 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

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