Siemens Building Technology 192-209 Stat 320735-701 this is an integrated control

this is an integrated control board that manages both the ignition sequence and the blower timing functions in a single component

It functions as a robust bridge for exhaust gas venting

Simplified Setup: Includes a low-fire bypass adjustment on the right side for easy field calibration of the minimum heat output

While it shares functions with other modules

the valve is likely restricted or the power head has lost its charge

Siemens Building Technology 192-209 Stat 320735-701 this is an integrated controlThe Siemens 192 209 is a high performance pneumatic room thermostat designed for 2 pipe building automation systems requiring precise control over both heating and cooling cycles. Engineered as part of the Powerstar 192 series, this dual setpoint unit features a reverse acting (RA) heating mode at 25 psi and a direct acting (DA) cooling mode at 18 psi. The bimetal sensing element provides a rapid temperature response of 0. 1F, ensuring stable
