Extended Probe Reach: The 10-7/8" insertion length allows for precise temperature monitoring in specific cabinet locations where standard short-probe switches fail to reach the core airflow

Mechanical Reliability: Beryllium copper feedback bellows provides high-cycle life and precise proportional pneumatic output

Using an LP orifice with natural gas will result in an insufficient pilot flame and ignition failure due to the different pressure requirements of the fuels

though it is adjustable within a 3" to 7" WC range to match specific manifold pressure requirements for various commercial and residential heating units

it utilizes patented differential voltage sensing technology to monitor auxiliary voltage with professional-grade precision
