To maintain proper damper blade positioning and system logic

installing this furnace pressure switch restores the safety circuit integrity

but it is specifically optimized for Reznor unit heaters

and conventional systems with modulating heat/cool outputs

This assembly functions as a direct replacement for the discontinued 233-41801-05B

Johnson Controls HE-69Y3-5NS0 Humid. 326058-757 To maintain proper damper bladeThe Johnson Controls HE 69Y3 5NS0 is a high performance 10k ohm Type III thermistor humidity and temperature sensor designed for precise environmental monitoring. Engineering for a duct surface mount configuration, this grey enclosure unit is the 025 36433 001 direct cross replacement for legacy systems. It provides a proportional 0 to 5 VDC output for relative humidity, ensuring ? 3% RH accuracy across a wide operating range. Built for HVAC
