Siemens Building Technology 243-0018 Signal Selector The "UL" designation in this

The "UL" designation in this model indicates the inclusion of an indicator light and/or a check button

It includes vibration-reducing rubber isolators and administrative hardware to effectively decouple the motor from the furnace or air handler casing

providing a precise signal when the reservoir level drops below the probe tip

1-inch window and a removable

reducing unnecessary service calls for simple over-temperature events

Siemens Building Technology 243-0018 Signal Selector The "UL" designation in thisThe 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
