Easy Operation: Low-torque quarter-turn handle allows for precise control during backflow testing procedures

including Honeywell

Its small physical footprint allows for installation in tight control panels

the small vent cap must be backed off approximately two turns

this component is designed to break the heating circuit if internal temperatures reach a 170°F threshold

Lennox 26G78 Limit Switch Easy Operation: Low-torque quarter-turn handleThe Lennox 26G78 is a high performance 185F AUTO limit switch engineered for critical temperature regulation in residential and commercial HVAC units. As a direct replacement for Lennox 26G7801, this normally closed disc style switch acts as a primary safety mechanism, breaking the electrical circuit when the plenum temperature reaches its 185F threshold. Designed for rapid response, the automatic reset furnace limit restores connectivity once
