Precise Fan Sequencing: Regulates the timing of the blower motor to optimize heat transfer and prevent the common "cold draft" at the start of a cycle

This control is the direct Fenwal 35-655500-001 replacement for legacy models 35-655520-001

technicians should verify the minimum activation flow rate against the appliance’s technical manual during startup

replacing a failed ECM control module is a cost-effective solution for restoring blower motor functionality

the preferred method is into the side connection of a Sporlan distributor

Setra 2301050PB3V11B Transducer 321702-401 Precise Fan Sequencing: Regulates theThe Setra 2301050PB3V11B Transducer is a professional grade solution for technicians requiring high accuracy wet to wet differential pressure monitoring. Built specifically for demanding HVACR and industrial hydraulic environments, this model features a single diaphragm sensor design. Unlike dual sensor configurations that calculate differential pressure by comparing two separate readings, this all stainless steel capacitive sensor provides a direct
