Trane SWT2978 Dual Pressure Switch Dual Pressure Switch

Dual Pressure Switch

It is one of many components that work together to provide increased efficiency and better control over your heating and cooling system, as well as its overall performance

The temperature on both sides of the pressure switch are adjustable

This allows installation in different type and size of buildings

And when it comes to heating and cooling, we trust Trane

This product replaced the SWT2977, which is no longer available

The switch also monitors the pressure in both stages for efficient operation

The Trane SWT2978 Dual Pressure Switch can be used on Trane air handlers that are applicable for use with whisper quiet technology

Heating and cooling is the foundation of our business

The Trane Dual Pressure Switch is designed to protect the compressor and evaporator coils from overcooling

The dual pressure switch provides a switch to operate two separate cooling/heating/ventilating/exhaust systems

One dual-pressure switch per system is required

If the head pressure reaches the same level as that of line pressure (indicating that demand has increased), Compressor B will be shut off and Compressor A will return to operation

Used in conjunction with an outdoor temperature sensor, the dual pressure switch works to match indoor and outdoor air temperatures by initiating a second compressor start

The Pressure Switch controls the operation of your unit

The Trane dual pressure switch is a device that controls the blower motor in a forced air heating and cooling system to activate or deactivate the blower motor

This is a replacement part for the Trane SWT2978 Dual Stage Heat Pump systems

The unit's high/low differential is adjustable between 0-30 PSI, allowing for precise control of operation within your specific system

It’s a powerful, efficient way to help you control energy costs by enabling you to operate your system based on outdoor conditions

The SWT2978 Dual Pressure Switch from Trane is engineered for reliability, performance and value

A dual pressure switch is a switch designed to control two separate functions

Designed to operate when the inlet pressure of the system drops below a set point, the switch is also equipped with an adjustable differential that controls when the fan or blower motor will cut on and off

If the temperature at the suction line drops below a certain point, this switch will turn off the air handler blower and stop cooling

It works by monitoring changes in temperature in both the cool and heat stages for optimum performance

Plus, its sealed plastic casing protects the switch from damage caused by humidity and moisture – which means that it can last longer and deliver more dependable performance over time

The Dual Pressure Switch is an exception to the current Air Conditioner, Heat Pump and Central Furnace wiring diagrams

The Trane® dual pressure switch is a two-stage cooling/heating switch that runs both stages of your air conditioner or heat pump at different times

The Trane SWT2978 Dual Pressure Switch is a part of the Trane brand of home comfort systems

If your system's blower motor is not working, then this may be the part you need

When compressor B is running, if outdoor temperatures rise above the set point of temperature C, the head pressure will begin to increase at a rate of approximately 1 inch (25 mm) per hour
