Lennox 2 Stage Pressue Switch Model 36w77/36w78

The 2 Stage Pressure Switch is used for furnaces and air conditioning systems. It monitors the inside temperature of your home to ensure proper heat or cooling is being provided. If the inside temperature falls below the set range, it will automatically increase the system's capacity to bring it back up to temperature.

The 2 Stage Pressure switch is designed to go onto existing air handlers. The top of the switch has an adjustable pressure shut off for drop-down noise control.

The 2 stage pressure switch uses the same gas valve to control your water heater as it does to control the gas fireplace, allowing separate temperature setting for both.

The Lennox® two stage pressure switch uses your current furnace blower motor to cycle the air conditioner compressor on and off. This means your air conditioner will only turn on when it needs to, which can reduce power use by 10% or more and save you money. Just wire in the pressure switch between your blower terminal and contactor coil.

The Lennox 36W77 2-stage Pressure Switch senses loss of downstream pressure and instantly redirects the air to the furnace's burner, preventing cold spots in your home and increasing your comfort level.
