The Wayne 100697-001 Aquastat is a mission-critical immersion-type controller engineered for precise temperature regulation in hydronic boiler systems and storage tanks

and cleanroom pressurization where maintaining a precise pressure boundary is a non-negotiable requirement for contractors

This package includes a precision-machined valve stem

Constructed from a durable aluminum and steel composite

Most failures occur due to a downstream short in the 24V circuit

Laars Heating Systems R0360900 Flame Sensor 319847-401 The Wayne 100697-001 Aquastat isThe Laars Heating Systems R0360900 Flame Sensor is a high precision OEM replacement part engineered for specific gas fired hydronic boilers and water heaters. Designed for direct spark ignition systems, this flame ionization sensor monitors combustion stability by detecting the presence of a pilot or main burner flame. This crucial component ensures the ignition module receives a consistent micro amp signal (typically ranging from 5 to 30 micro amps),
