Siemens Building Technology 243-0018 Signal Selector This design requires a technician

This design requires a technician to physically inspect the burner compartment and reset the small button on the back of the part

A faulty switch typically causes the furnace to short cycle

ensuring the system operates within precise setpoint tolerances

as it provides a higher dielectric strength against voltage spikes

though a clean sensor should ideally produce 2

Siemens Building Technology 243-0018 Signal Selector This design requires a technicianThe Siemens Building Technology 243 0018 Signal Selector is a high performance, dual input pneumatic logic device designed to compare two proportional air signals and transmit the higher value to downstream controllers or final control elements. As the direct replacement for RCC 1108, this highest pressure signal selector is essential for optimizing pneumatic control systems that require precise demand based logic, such as multi zone cooling
