CAUTION
Equipment Damage Hazard.
Not recommended for averaging sensor lines.
For averaging sensor lines use the RP922A
Pneumatic Potentiometer.
Because input signal air flows from higher to lower, do
not use the RP973A on bleed-type thermostat lines. To
average bleed-type devices, use an isolating (repeating)
circuit. See Fig. 6. Refer to Fig. 7 for a typical application.
