Reznor 210761 Oil Temperature Control 170F/15'Diff

The Reznor 210761 Oil Temperature Control used as a specialized thermal monitoring switch designed to regulate fuel heating cycles within oil-fired HVAC systems. This mechanical thermostat is calibrated to a fixed 170F setpoint, operating on standard circuitry to ensure the burner assembly receives fuel at the precise viscosity required for efficient combustion. It is installed within the preheater manifold, this control prevents the ignition process from engaging until the oil reaches its optimal operating temperature. By maintaining this thermal threshold, the component acts as a vital safety and performance gatekeeper, for protecting the heat exchanger from soot buildup.
