Enhanced System Safety: Provides a verified barrier against combustion bypass

Multi-Speed Flexibility: Features 3-speed taps to optimize system CFM and improve latent heat removal

the SPDT (Single-Pole Double-Throw) configuration allows you to wire the thermostat to either break the circuit on temperature rise (heating) or make the circuit on temperature rise (cooling)

Industrial Durability: Robust aluminum housing and Teflon-coated internals provide resistance to corrosion and wear

which can lead to oil acidification and mechanical failure
