The Honeywell RP920A1033 proportional, high capacity, single or dual input pneumatic controller is used in conjunction with remote sensors to provide proportional (P) or proportional plus integral (P+I) control of temperature, humidity, pressure, or dewpoint for heating and air conditioning systems. Replacement devices are available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell controllers.
Features
The RP920A1033's proportional plus integral control option minimizes offset. Miniature diaphragm technology provides high degree of accuracy and reliability. Direct Acting models can be converted to Reverse Acting (RA) function in field. Includes field-adjustable compensation start point, local or remote setpoint field option, integral action cut-off providing trouble-free automatic startup, optional transparent cover providing protection while allowing easy reading of settings and gages and corrosion resistant construction.
