KMC Controls RCC-1001 Reversing Relay the sensor should be openThe KMC Controls RCC 1001 Reversing Relay is an essential proportional device for pneumatic control systems, engineered to invert signal outputs from a controlling device. This specific pneumatic reversing relay is factory calibrated to a 9 PSI crossover point, effectively decreasing branch line pressure as input pressure increases. Designed for field proven reliability in HVAC applications, the RCC 1001 includes bias adjustment capabilities, allowing
