To maintain ASME compliance
Its robust construction minimizes mechanical wear
Resistance will increase as the outdoor temperature drops
meaning it triggers an open circuit at 105°F and restores the connection when temperatures drop to 73°F
Durable Construction: Built with a standard nut configuration to withstand high-pressure hydronic environments while maintaining electrical continuity
Laars Heating Systems R2080201 Kit 318973-401 To maintain ASME complianceThe Laars Heating Systems R2080201 Kit is a field proven temperature control conversion kit engineered to transition existing FX05 controllers over to the more robust Watlow series. As a critical boiler control board upgrade, this kit resolves the obsolescence of the Laars 2400 439 part, ensuring that legacy hydronic systems maintain precise thermal regulation. For technicians managing commercial boiler maintenance, this FX05 to Watlow conversion
