As a CSA-certified spark electrode

Thermal Protection: Features internal automatic reset thermal overload protection to prevent coil burnout

meaning it will restore the circuit once the plenum temperature cools back to the 180F differential

linear resistance data to maintain optimal environmental setpoints and system efficiency

Broad Compatibility: Direct fit for Reznor F-165 through F-400 models

Enviro-tec PE-27-0042 Controller Freon As a CSA-certified spark electrodeThe Enviro tec PE 27 0042 Controller serves as the direct OEM replacement for the ETFC120 10, providing precise control for SCR fan motor applications in VAV terminals and blower coils. Engineered for 120V input, this solid state speed controller manages motors ranging from 1 4 HP to 3 4 HP, ensuring stable performance across varying static pressures. It functions as a proportional controller, translating a 0 10VDC or 2 10VDC signal into a specific
