Siemens Building Technology VVG44.15-1.6 Valve 326058-757 delivering the precise static pressure

delivering the precise static pressure required to maintain safe combustion airflows in residential furnaces

When performing a boiler pump repair

this thermostat provides both integral temperature sensing and manual setpoint adjustment within a 60-85°F range

this means a significant reduction in labor hours compared to sourcing individual fittings

This 24Vac digital thermostat cannot operate directly with 750mV or millivolt gas heating systems
